  • Drobo FS vs Lime Technology unRAID vs FreeNAS

    - by elluca
    I already decided to by a drobo fs until I just found these two tests: http://www.digitalversus.com/data-robotics-drobo-fs-p889_9543_487.html http://www.digitalversus.com/lime-technology-unraid-p889_8992_473.html The two cons agains drobo for me: loudness price What disadvantages has the unraid stuff against the drobo fs? Has it also got that ease of use like swapping drives on the go, simply extend capacity by plugging in new drives, notify me of drive errors, disk failure protection, dynamic space of "partitions", better/worse effective capacity, etc. Which is more secure? Am I able to simply replace a bad drive with a new one on unraid? What happens if my pc fails? Lets say the cpu overheats. Since I have a complete pc which is going to be replaced, I only have to pay the software to use unraid. I am going to use my nas for: music library (how well does it integrate with iTunes? ) picture library movie library development (i need to be able to be to use time machine) I am going to use this nas with a MacBook pro. My current disks: 2x 500Gb 1x 1.5Tb 1x 2Tb On a drobo fs I would have 2.26 Tb of space. What would it be on unraid? Is FreeNAS also an alternative?

  • Security and data backup for Ubuntu usb installation

    - by AMS949
    Due to encryption on my corporate laptop I opted to install Ubuntu 9.10 on a flash drive and just use it as my hard drive. I tried the vmware but it crashed my xp a couple of times. Now I have a couple of concerns since I am totally new to Ubuntu and Linux. First, would it be possible for me to transfer my installation to a new usb drive? I now have a 4gb and it may get filled up soon, I don't seem to be able to see my actual files when I browse the usb drive. I also tried copying all files from this usb to another and boot from it but that failed. Second, whenever the system boots up I am never prompted for a password, it is always the username ubuntu. Which I guess means if I lose my usb drive my data is open wide. Is there a way to secure it or to use users and groups as on a regular hard drive installation? As a background, I created this by going into a working Ubuntu installation, System - Administration - USB Starter Disk Creator (was that the right way to start with?) Thanks!

  • online backup plan for a home office with servers

    - by TiernanO
    So, i am in the process of tweaking my spending and i need to change my backup plan... I am currently using a mix of JungleDisk and ZManda ZCB to backup files on my MacBook Pro, Main Windows Server Wrokstation, a dedicated Windows Server in a datacenter, and various other machines and file sources. The problem is the cost: this month, it has cost me about $90 to backup a little over 500Gb... This amount of data will increese over time too, since i am backing up Photos (24Mb RAW images + 4-8MB JPEGs), Videos (various cameras shooting 720p and 1080p), Music, Movies, TV shows and Apps from iTunes (though with iTunes cloud, this might not need to be backed up again) and source code... I have looked at the likes of Mozy, CrashPlan+ and Pro, Backblaze and Carbonite, but each have their problems: Mozy seems overly expenvice per gig at 50C Crashplan wont sell to me since i am outside the US (they hide it on their site... hidden in the FAQ section!) Backblaze dont support Windows Server Carbonite business pricing is $600 up front for 500Gb of storage... Fro $229, they will not backup Windows Servers. So, other than those, Jungle Disk (at 15c per Gig) or ZManda (also at 15c per Gig) what other options are there? what are other people using?

  • OS X Keeps prompting me for SSH private key passphrase (OS X 10.6.8)

    - by Danny Englander
    I have a private key to ssh into my server and the connection works. In my hosts file I have: Host myhost HostName xxx.xxx.xxx.xx GlobalKnownHostsFile ~/.ssh/known_hosts port 22 User myuser IdentityFile ~/.ssh/mykey_dsa IdentitiesOnly yes .. and then I type ssh myhost Every time I connect, I get the Mac OS X keychain prompt and I tell OS X to remember the passphrase but then when I disconnect from ssh and re-connect, I am prompted to add the passphrase to the keychain again. This is only a recent problem so I suspect and issue with Keychain? To be clear, I can 're-add' to keychain every time and connect but this defats the purpose. The permissions on my dsa key are set at 600 or -rw-------@ I tried repairing disk permissions but that did no good. My Google-foo is also failing me, nothing of use came up. So I am not sure if this an OS X / keychain issue or an SSH issue. update: When I try ssh -vvv myhost, I think it reveals the issue: debug1: Trying private key: /Users/danny/.ssh/mykey_dsa debug1: PEM_read_PrivateKey failed debug1: read PEM private key done: type <unknown> debug3: Not a RSA1 key file /Users/danny/.ssh/mykey_dsa. debug1: read PEM private key done: type DSA Identity added: /Users/danny/.ssh/mykey_dsa (/Users/danny/.ssh/mykey_dsa) debug1: read PEM private key done: type DSA debug3: sign_and_send_pubkey debug2: we sent a publickey packet, wait for reply debug1: Authentication succeeded (publickey). ... and after that I get connected. I think this crux of the matter is: PEM_read_PrivateKey failed

  • Accidentally mounted a ReiserFS drive as MBR on my windows box - how do I recover?

    - by Ryan
    I had a WD Netcenter with a 160GB drive that kept dropping off the network. I opened up the enclosure and removed the hard drive, connected to a Windows box without knowing the drive used ReiserFS.... When mounting on the Windows box, I chose "MBR" as filesystem. 70GB of data corrupted: 90% of data is word documents, excel spreadsheets, and jpg's - all mission critical. Attempted recovery on Linux box (ubuntu) using TestDisk: I could see the container, but couldn't get anything out – according to TestDisk this was because I chose "none" as filesystem. Attempted recovery using Nucleus Kernel Recovery for windows: 98% of what was recovered is incomplete and/or unusable. I need to know if a way exists to recover or rebuild original ReiserFS MBR, or what tools/techniques might give me the best results in recovering the data. Found a Windows version of TestDisk and I ran it yesterday - here are the results: TestDisk 6.14-WIP, Data Recovery Utility, May 2012 Christophe GRENIER <[email protected]> http://www.cgsecurity.org Disk /dev/sda - 160 GB / 149 GiB - CHS 19457 255 63 The harddisk (160 GB / 149 GiB) seems too small!

  • Dell PowerEdge 1600SC Server won't boot from Fedora 12 DVD because of CD only drive.

    - by studiohack23
    Dell PowerEdge 1600SC Server won't boot from Fedora 12 DVD in the drive because it only supports CDs as I found out after the fact. I'm a complete novice @ servers, so if you need more detail, let me know, and I'll try to provide it. This server is around 4-6 years old. it has "PXE" boot, not sure what that means? This particular server has 3 RAID hard drives. As far as I know, they have all been wiped. I looked up the service tag on Dell, and it has: Compact Disk Drive, 650M, I Internal, Half Height, 48X, BlackHitachi LG Data Storage as its CD drive. Thus, the CD drive does not support DVDs, so installation will have to be via a live CD. However, I'm trying to put Amahi Home Server (http://www.amahi.org/), and Live CD/USB stick installs are not recommended unless one is an expert Linux user. any suggestions as to how to get around this? PROBLEM SOLVED! THANKS for all the help!

  • Flushing iptables broke my pipe, how can I save my instance?

    - by Niels
    I was setting up my iptables when I performed a iptables -F and my ssh pipe broke. This is the last output of my session: root@alfapaints:~# iptables -L Chain INPUT (policy DROP) target prot opt source destination ACCEPT all -- anywhere anywhere ACCEPT tcp -- anywhere anywhere state NEW,ESTABLISHED tcp dpt:2222 ACCEPT tcp -- li465-68.members.linode.com anywhere state NEW,ESTABLISHED tcp dpt:nrpe ACCEPT tcp -- anywhere anywhere tcp dpt:9200 state NEW,ESTABLISHED ACCEPT tcp -- anywhere anywhere tcp dpt:http state NEW,ESTABLISHED ACCEPT udp -- anywhere anywhere udp spt:domain Chain FORWARD (policy DROP) target prot opt source destination Chain OUTPUT (policy DROP) target prot opt source destination ACCEPT all -- anywhere anywhere ACCEPT tcp -- anywhere anywhere state ESTABLISHED tcp spt:2222 ACCEPT tcp -- anywhere anywhere state ESTABLISHED tcp spt:nrpe ACCEPT tcp -- anywhere anywhere tcp spt:9200 state ESTABLISHED ACCEPT tcp -- anywhere anywhere tcp spt:http state ESTABLISHED ACCEPT udp -- anywhere anywhere udp dpt:domain root@alfapaints:~# iptables -F Write failed: Broken pipe I tested my connection just before and I was able to connect with ssh. Now I did a nmap scan and not a single port is open anymore. I know my VPS is running on VMWare ESXi, could a reboot help? Or if not could I attach and mount the disk to another vm to save the data? Does anybody have some advise? And maybe an explanation what happend or what could have cause my pipe to break? ps: I didn't save my rules on the config directories of iptables. But used a file I stored in ~/rules.config to apply my rules like this: iptables-restore < rules.config So probably a reboot would help? Thanks a lot in advance.

  • Windows XP consuming drive letters

    - by billdehaan
    This one's a bit of a stumper. I'm running XP SP3, current with all fixes, etc. My problem is that I can assign a drive letter to a container file (explained below), it works just fine. But once I close the container, the drive letter is no longer available until the next boot. I've got some confidential data that I've placed in a container volume. I've used TrueCrypt (www.truecrypt.com) and FreeOTFE (www.freeotfe.org), with both installed and portable versions for both, with the same result. I open the container file, assign it to a drive letter (say R:), and run some portable apps that are within the volume. When I'm done, I close the container, and the drive letter is released. Fine so far. However, when I attempt to re-open it, the previous drive letter (in this case R:) is no longer available. It's not mapped to anything, it's just unavailable. Even attempting something like "subst R: C:\" returns "Invalid Parameter - R:". I can use the S: drive, no problem, but the next day I have to use T:, then U:, etc. Eventually, I have to reboot to reclaim all of of the drive letters. Unfortunately, everything I've read about drive letters relates to USB assignments, which doesn't apply here. I've tried the "show hidden" command (set devmgr_show_nonpresent_devices=1) with no success. And the Disk Management tool doesn't apply either, since it's not a physical drive. Does anyone know where Windows keeps the list of drive letters? And is there anything short of a reboot that can be used to reset it?

  • SQL Server 2005 SP3 on Windows 7 - No Management Studio

    - by Mike Thomas
    I've been trying for a day and a half now to get SQL Server 2005, DEV edition, to work on Windows 7, 64 bit prof. I install from the disk, then run SP 3. I get a failure on the Client Components section of the Installation Progress along with this vague message - Product : Client Components Product Version (Previous): 1399 Product Version (Final) : Status : Failure Log File : C:\Program Files\Microsoft SQL Server\90\Setup Bootstrap\LOG\Hotfix\SQLTools9_Hotfix_KB955706_sqlrun_tools.msp.log Error Number : 1712 Error Description : MSP Error: 1712 One or more of the files required to restore your computer to its previous state could not be found. Restoration will not be possible. I've uninstalled all Visual Studio and tried to make this as clean as possible, and have read a lot of the blog posts, but am really at my wits end about this. I am not a DBA, but I use SQL Server all the time when coding and testing apps. Does anyone have any ideas as to where I can get this sorted out? I've been ati this for a long time and have never encountered an installation as bad as this one. Thanks Mike Thomas

  • Why can't I see installed AIR applications in /Applications on Mac OS Lion?

    - by Damir Zekic
    Yesterday I did a clean install of Mac OS Lion, and installed bunch of apps, including HipChat Desktop Application (an Adobe AIR app). I used it for some time and eventually closed it. Today I wanted to start it again, but couldn't find it in Launchpad. I looked in /Applications folder, but I couldn't find it there either (I still don't have ~/Applications). I went back to HipChat website (from where I installed) and a Flash plugin allowed me to run the app immediately. It shows up in my Dock and if I "keep it" there, I can launch it again (it still doesn't appear in my /Applications dir). However, it asks me for confirmation about launching an app that has been downloaded from the Internet (every time I start it, it's annoying). I also see the app in Adobe AIR uninstaller. I then went to my old Snow Leopard installation and found HipChat in my /Applications folder there. Copied it to the Lion disk and it works. Now I have two HipChat entries in Adobe AIR uninstaller. I guess I solved the issue at hand, but I still don't understand where the original app is located and how I can access it and move it to Applications. I couldn't find it anywhere with both Finder search nor find command in terminal (I used $find / -name "HipChat*" -print). So, how does Adobe AIR store the installed applications (on OSX Lion) and is there any way to get them to show up in Launchpad?

  • On Windows and Windows 7's Task Manager, why Memory is 1118MB Available but only 62MB Free? [closed]

    - by Jian Lin
    Possible Duplicate: Windows 7 memory usage What are the "Cached", "Available", and "Free" memory in the following picture (From Windows 7's Task Manager). If it is 1118MB Available, then why isn't it Free (to use)? As I understand it, if a bowl of noodle is available, that doesn't mean it is free... it may still cost $7. But what about in the Task Manager, when it is Available, it is also not Free? Does it cost $2 per MB? What about the "Cached"... What exactly is the Cached Memory? We may put some hard disk data in RAM and so we cache the data in RAM, for faster access (that's the operating system's job). So the Total Physical RAM is 6GB, what is the 1106 Cached? Cached in where? Caching physical RAM in ... some where? It is also strange that the Cached value is sometimes higher and sometimes lower than the Available value. Can somebody who is knowledgeable about this shred some light on these meanings?

  • Move an existing RAID 5 array from Ubuntu to Gentoo

    - by Cocoabean
    I have a 64-bit Ubuntu machine with a 4-disk RAID 5 using software raid (md). I've been able to boot an Ubuntu LiveCD and recognize the array with a simple mdadm -A /dev/md0. It was easy to mount after that and nothing had to rebuild. I'm installing Gentoo on this box now (multi-boot, non-RAID root partition) and I have md auto-detect turned on in the kernel. When I boot Gentoo I get: "invalid superblock magic on sdd" for each of the drives in the array. I boot back to Ubuntu and they mount no problem. I tried copying the mdadm.conf that works in Ubuntu to Gentoo, and then ran mdadm -A /dev/md0 but it reports that there is no array named md0. I don't want to lose data (obviously) and I don't want to have to let the RAID rebuild every time I switch between OSes. Any help is appreciated. Both are using mdadm 3.1.4 Both are running 64-bit kernels. mdadm -D /dev/md0 from Ubuntu yields: http://pastebin.com/5gj2QNkV UPDATE: After rebooting I noticed that it still complains about invalid blocks, but cat /proc/mdstat shows an inactive /dev/md127 with the same disks as my raid. I want to mount it but I don't want to get stuck waiting for a rebuild or destroying it inadvertently. mdadm -D /dev/md127 Here is pastebin of mdadm -D /dev/md127 on gentoo: http://pastebin.com/gDCWn0Rn UPDATE II: dmesg output about 'invalid raid superblocks' http://paste.ubuntu.com/885471/ fdisk -l from Ubuntu, /dev/md0 does not have any partitions but I do have it mounted and accessible: http://paste.ubuntu.com/885475/

  • Physical-to-virtual for personal use

    - by Journeyman Geek
    One of my current projects involves reducing the number of old computers lying around. So far, the office systems have been downsized from 5 to 2. One system which had no data on it was dumped entirely, while three other identical boxes were consolidated into to one (I swap hard drives as needed and they just work(tm)). I want to make further cuts. The physical systems in question all run windows xp sp3, and were old Pentium 4s with 256 MB of RAM. Currently, I have got a VirtualBox running on another system. My intention is to migrate all services to that. We can assume that disk space and RAM on the host is not an issue. I'd rather not go with a client-server physical-to-virtual (P2V) method like what VirtualBox uses now. I have a few specific concerns as well - specifically whether I'd need to reactivate or sysprep for dissimilar hardware first. An offline tool for imaging (Windows or Linux) would not be an issue since the drives could be mounted onto another system I have anyway or I could use a LiveCD. What would be my options for P2V conversion, and what would I need to keep in mind when doing this?

  • Windows 7 Loading Very Slow

    - by Adnan
    Hi guys, I've had a problem that only started to occur yesterday. When I boot into Windows 7 and log on to my user account, the computer gets very laggy and slow for at least 5 minutes. Icons take ages to load, and everything is rendered unclickable. This happens for about five minutes after which everything goes back to normal. I tried restarting a few times to see if this is a recurring problem, and it is. I ran a full system scan with Microsoft Security Essentials and found nothing wrong, and I also defragmented the disk to increase performance. However, the problem still exists. Edit: For the past day, I've been trying to install Ubuntu on the same laptop. When installing it on a partition didn't work, I decided to use Wubi. Could this somehow be the problem? Also, my hard drive gets hot a lot, so could the heat be affecting the hard drive and maybe making it defective? Any help on this issue would be greatly, greatly appreciated.

  • Seeking web-based FTP client for very large file upload

    - by Paul M. Nguyen
    I have looked around for these for some time... the limits imposed by the web server and/or the dynamic programming environment (e.g. PHP) are far too restrictive for the application I'm working on. We need to be able to move large graphics and video files to and from clients (ranging from tens of MB to a few GB in a single file). Plain FTP with a proper desktop client will do the trick, and we're hosting this in Amazon EC2 with EBS. User management will be done from the office via webmin. Users are chroot-jailed into their home dir by proftpd. net2ftp will work for many clients, but we often need to move single files that approach 1GB or exceed 2-3GB which is way out of the range of any http-based uploader. So we turn to Java or Flash - can they do it? From within the web browser establish an FTP connection and grab a huge file? There are licensed applets and such out there, but none seem convincing. Again, I'm looking for some code that can speak FTP and read (& write?) the local disk, that is delivered in a web browser, and can move single files of 2GB+. The reason for having a web-based interface to FTP is to skip the software installation step for our clients. I will consider proper desktop client software as long as it's "portable" and at least Win+Mac and can be easily configured by lay-man users in a hurry.

  • Windows 7 boot failure after update

    - by Jake
    Installed some windows 7 updates today, mostly just optional fixes and it installed an update to my IntelliType or IntelliPoint drivers (Keyboard & Mouse). It asked to reboot, computer gets to the windows load screen and redirects to the repair utility. Repair utility failed, it said if I recently installed a device, unplug it and try to restart. So I unplugged my keyboard and mouse, restarted. Nothing. I noticed that all the errors seemed to be Windows 7 thinking the installation was on another one of my slave drives. For example, my windows installation is on C:, but I have other drives, like G:, X:, etc... So it said "Critical Boot File G:\Windows\system32\drivers\amdxata.sys is corrupt, but why not C:\ ? So I unplugged ALL other hard drives, it still tried loading X:, even though the only one plugged in was C: I have the windows disk, but that didn't seem to help. I was thinking I need to fix my boot.ini or something simple like that was corrupt, the hard drives seem fine. I'm screwed, it's finals week.

  • W2K INACCESSIBLE_BOOT_DEVICE, with System Commander

    - by Gary Kephart
    I have a system that was originally had Win NT. I added System Commander (SC7) and then added W2K. The relevant partitions are: 0 - Primary - MultiFAT (Has Win NT, mapped to C:) 1 - Extended - with many logical partitions: 1.1 NTFS which has W2K and is mapped to D: 1.2 other logical partitions which are irrelevant to this D: was getting full. It needed room for virus definitions and Windows upgrades. In the past, I had simple used SC7 to resize D: without problems. So I did it again this time. However, upon finishing, I got the message "Unable to create partition". It also marked the partition as unformatted. I checked that the files on the disk were still there using SC7's Partition Explorer, and they were there. I continued and the system managed to boot up fine anyways. Then I rebooted the system again. This time, I got a message saying "INACCESSIBLE_BOOT_DEVICE". I went back in to SC7 and to Partition Commander, and it was still saying that the partition was unformatted but the Partition Explorer still showed the files on the system. I finally decided to resize the partition again, figuring that this would force a rewrite of the partition information. That seemed to work, until I had to reboot again. Now I can't see the files using Partition Explorer, and the Resize button is now disabled. What now?

  • I need an admin toolset for Windows 2003 and 2008

    - by eugeneK
    i know this is way too general question but anyway. I need few tools, will write down my tasks as sysadmin and if you have any to automate my job i would be glad to hear. I don't mind paying for software needed unless it is way too expensive. First of i backup all files on server at local/office storage. I 7zip all SQL backup files and then move them over network to centralized location and then FTP them from office PC which has no FTP server installed and cannot have one. Backups happen at 4AM at the morning thus i need to set time for compressing and afterward FTPing. Then i FTP all IIS web application as differentiation backup, same goes for VOD movies. Second tool i need is system monitor which will monitor all servers from themselves and from external location for CPU/Memory/Hard disk and other basic failures. This tool should able to execute Website address with parameters which will send me an email with all report on failure. Third tool i need is a way to get all Event Logs from 10 Windows based servers without accessing each any of them manually. If you know any solution, thanks in advance.

  • How long will a USB key with an OS installed on it last?

    - by Xananax
    I've heard numerous times that installing an OS on a USB key is a bad thing to do, as USBs typically have a certain number of writes before dying, and installing an OS on it will wear it out (unless it's used sporadically for rescue purposes). Nonetheless, I am very tempted to install some flavour of Linux (Ubuntu or Arch, I haven't decided yet) on a small, transportable, USB Key. My problem is, although you read a lot that it's "bad", you are never told how bad. How long would it last (provided, say, a pc that is 24/7 on)? A month? A year? Five years? Is there recipes to make it last longer? Is there any reason beside weariness that should prevent me from attempting this? I mean, if it can be calculated, then I could theoretically shield myself by doing regular backups on another key when the deadline gets close (for example). Notes I am not talking of using a USB as a live CD, but actually installing the OS on it.) When I say "USB Key", I refer to the little USBs with a flash memory, not an external USB hard drive. For the curious, my reason is that I work in a lot of different places, on different PCs, and I have a very customized session, with my own WM, my own key bindings, my own scripts, , a selection of plugins for firefox and chrome, etc, and currently I am synchronizing all this through a mix of dropbox, git, and transporting files on USBs, and and it's becoming a chore. It would be much simpler for me to just plug the USB and mount the hard disk of the PC I am using and use it's processing power without actually needing to install any OS on it.

  • Backup hardware and strategy on distributed Windows Server 2008 network

    - by CesarGon
    This question is a follow up to this. We have a Windows Server 2008 R2 domain over a network that spans two different buildings, linked by a 100-Mbps point-to-point line. Over 60 users work in the organisation. We are planning to use DFS folders and DFS replication for file serving across the organisation. The estimated data volume is over 2 TB, and will grow at approximately 20% annually. The idea is to set up a DFS file server in each building and use DFS so that all the contents stay replicated over the 100-Mbps link. We are now considering backup hardware and strategies. We are Dell customers and, after browsing the online Dell catalogue, I can see a number of backup hardware options. My main doubts are the following: Would you go for a tape library, disk backup, or are there other options worth considering? Would you perform batch backups (i.e. nightly) or would you use continuous backup (i.e. while users are working)? Would you use a dedicated backup server to which the tape library (or any other backup device) is attached, or is there any other alternative way of doing things? My experience with backup hardware and overall setup is limited, so I appreciate any good piece of advice that you may have. Thanks.

  • What does a status of "Backup" mean for Windows 7 local user profiles?

    - by Howiecamp
    Summary: Upon logging on to Windows 7 RTM I get a message that my profile can't be loaded and a temporary user profile is created. I logged off and back on as Administrator. The user profiles dialog shows my user profile with a Type of "Local" and a Status of "Backup" rather than "Local" which it should be. How can I change this to make my user profile accessible? The long story: My PC has a single hard drive partitioned into a C: and a D:. I'd moved my user profile directory (c:\Users) to d:\Users, removed c:\Users and then used mklink.exe to create a directory symbolic link c:\Users -- d:\Users. Worked like a charm since I did it. Today, I make a System Restore Point for drives C: and D:. Next, I dismounted D: and used the Disk Management tool to remove the "D:" drive letter from the D volume. (My plan was to reboot and then redirect the symbolic link.) Upon reboot, I got the user profile error described above. Finally, I restored the System Restore Points that I'd created for both drives and then rebooted again. Same issue.

  • Password Cracking Windows Accounts

    - by Kevin
    At work we have laptops with encrypted harddrives. Most developers here (on occasion I have been guilty of it too) leave their laptops in hibernate mode when they take them home at night. Obviously, Windows (i.e. there is a program running in the background which does it for windows) must have a method to unencrypt the data on the drive, or it wouldn't be able to access it. That being said, I always thought that leaving a windows machine on in hibernate mode in a non-secure place (not at work on a lock) is a security threat, because someone could take the machine, leave it running, hack the windows accounts and use it to encrypt the data and steal the information. When I got to thinking about how I would go about breaking into the windows system without restarting it, I couldn't figure out if it was possible. I know it is possible to write a program to crack windows passwords once you have access to the appropriate file(s). But is it possible to execute a program from a locked Windows system that would do this? I don't know of a way to do it, but I am not a Windows expert. If so, is there a way to prevent it? I don't want to expose security vulnerabilities about how to do it, so I would ask that someone wouldn't post the necessary steps in details, but if someone could say something like "Yes, it's possible the USB drive allows arbitrary execution," that would be great! EDIT: The idea being with the encryption is that you can't reboot the system, because once you do, the disk encryption on the system requires a login before being able to start windows. With the machine being in hibernate, the system owner has already bypassed the encryption for the attacker, leaving windows as the only line of defense to protect the data.

  • Running a VM off a USB 2.0 Flash Drive - Mac/Parallels/XP

    - by geerlingguy
    I use a MacBook Air as my primary machine, and the 128GB SSD means space is precious. To save about 10 GB, I've been running Parallels with a Windows XP VM off an external USB hard drive, which performs as well in everyday use as running the VM off the internal SSD. So, I bought a tiny 32GB USB 2.0 flash drive, plugged it into the MacBook Air, formatted it first as ExFAT (which was slow), then as Mac OS Extended (Journaled) (which was also slow), and copied over my VM file, and ran Parallels off it. My full experience is documented here: http://www.midwesternmac.com/blogs/jeff-geerling/running-windows-xp-vm Straight file copies are really fast — 30 MB/sec read (solid the whole time), and 10-11 MB/sec write (solid the whole time). But I noticed that once XP started running, the disk access rates were in the low KB ranges. Are USB flash drives really that poor at random access, or could I possibly be missing something (the format of the flash drive, etc.?)? Of note, I've tried the following, to no great effect: Formatting the drive as either ExFAT or Mac OS Extended (Journaled) Unplugging all other USB devices and turning off Bluetooth (which runs on the right-side-port USB bus). Plugging in the flash drive either direct in the right side port, or the left side port, or into a USB 2.0 hub
