• How to configure Time Machine to also backup an connected external hard drive?

  - by Another Registered User

  I've inserted a sweet SSD into my MacBook Pro, but it had limited space. So I had to export 60 GB of Data to an external hard drive. But now, when I run TimeMachine to backup my stuff, of course it only backups what's on the system disk. Is there a way how to also backup the connected external hard drive together with TimeMachine? Maybe there's a trick to get this work, with a fake folder that's actually the mounted drive? What could I do?

• Dual boot windows 8 pro and windows 7 on XPS 8500 Special additon

  - by Jesse

  I am trying to install a dual boot with windows 7 premium and windows 8 Pro on an XPS 8500 special edition. I created a new primary partition on my C: drive, inserted the windows 8 install disk, and rebooted my computer from DVD. I select custom install and the dialog box saying where do you want to install windows at? pops up but none of my drives are listed. Please help me determine what is going on? I don't understand why none of my drives are showing up on this menu. Not even the original drive. When I go to load driver and click on the partition I created it tells me "No signed device drivers were found. Make sure the installation media contains the correct drivers, and then click OK."

• Finding throuput of CPU and Hardrive on Solaris

  - by Jim

  How do I find the throughput of a CPU and the hard disk on an OpenSolaris machine? Using mpstat or iostat? I'm having a hard time identifying the throughput if it is given at all in the commands output. For example, in mpstat there is very little explanation as to what the columns mean. I've been using the syscl column divided by time interval to find the throughput but to be honest I have no idea what a system call truly is. I'm trying to to analyze a hardrive and CPU while writing a file to the hardisk and when at rest.

• Deleting a partition on dual boot

  - by blade4

  I have split my C:\ physical disk into 3 seperate partitions: C, H, and K. C has my original OS and is the active partition, H has another OS (dual boot), and K has song files. I want to keep the other OS (Windows Server) and when I am in this OS, I can't delete C ("Windows cannot format this partition"). What is the best way for me to get rid of C, keep all the songs intact, and the Server OS partition, so I replace C with another OS, and then get rid of the original Windows Server OS (So revert the dual boot to a single boot).

• Macrium Reflect Server v5 for Server Cloning?

  - by Stephane

  I'm starting to have clients with basic windows server setups. They have data backups, but no real strategy for system backups. I've been looking at cloning software which with linux or images seems easy enough (aside from DC complications, and other things I'm going to ignore until I learn more). What do people do when you have a non-disk hardware failure? I"ve been looking at server migration backup solutions and this one seems to be the cheapest. Anyone tried this? What more do I need to do to safeguard server setups? The hardware on these systems is a little out of date with Server 2003 setup at both businesses. Thanks!

• kvm process has too large a memory footprint on host

  - by gucki

  I'm using latest ubuntu quantal and start a kvm guest which should have 2048 MB of memory. Now after a few hours I can see that the kvm process of this guest is around 2700 MB, so 700 MB more than the guest should be able to consume.

• How do I install yum on Redhat Enterprise 4?

  - by Bob Cross

  For historical reasons, one of the machines that I manage has a Redhat Enterprise 4 boot disk (among others). Every now and then, we have to boot into RHEL4 to bring up some of the legacy software that we support and connect to. Since it's a fringe system, the Redhat support has long since lapsed and I can't convince myself that it would be worth paying just to get RPMs that I can go and get for myself. That said, the default RHEL tools are heavily biased against letting you do exactly that. I would like to install yum and use that as my package discovery and installation. So, is there an installation guide to integrating yum with an older RHEL 4 system?

• Partition falsly recognized as RAW

  - by Paul Hiemstra

  On my 2 TB data disk I have two primary partitions, one of 1.6 TB for data storage in Linux (ext3) and one of 300 GB for some additional data storage for Windows. I run a dual-boot Windows 7/Ubuntu 12.04 install. The issue I have that if I start my computer into Windows 7, bot the partitions on my 2TB data drive are not recognized. In stead, Windows 7 sees one 1TB partition with type RAW. However, if I reboot to Linux, and then back to Windows 7, the partitions are correctly recognized. The following two screenshots illustrate my situation. Before I reboot to linux: and after the reboot: I have two questions: What could cause this behavior? How can I solve this issue.

• Windows 7 pagefile size with large RAM and SSD

  - by Avi

  I've just upgraded my Windows 7 machine from 12GB to 24GB - both for running more VMs and for future proofing. My C driver is an SSD with 129GB formatted size. I was surprised to find out that the SSD only has 68GB free (most of my files are on D: to G:). Researching I found 24GB of my precious C: SSD are taken for virtual memory. So - do I need such large amounts of virtual memory when I have 24GB or RAM? I bought this size of memory so I"d not have to go to disk...

• Can I redeploy Citrix Xencenter Images in Amazon EC2?

  - by Mike Pinch

  Okay - I'm running Citrix Xencenter in my datacenter. My understanding is that Amazon EC2 is a very customized flavor of Xencenter. Based on that, I would like to know whether there is a method to utilize the .VHD disk images generated by Citrix Xencenter in the Amazon EC2 cloud. I realize that I can install tools into the OS and make my own images but that is not what I'm looking for. I'd like the efficiency of taking the images and redeploying them, or at least converting then redeploying. I basically would like to have all my backups running in the cloud, so that is my motivation.

• How to automate slipstream?

  - by Gregory MOUSSAT

  Since years I use slipstreamed Windows installations. This works very well, but preparing them is tedious : 1 - install a Windows with the last slipstreamed version we have (automated install) 2 - check Windowsupdate to see what's new, and take note 3 - download each new update available 4 - go to step 2 until no new update is available 5 - slipstream them into the last version we have (I already automated this step) I'd like a way to automate parts or all of this. Maybe a program able to know which updates are installed (already saw one, I don't remember which, and I know PowerShell can do this)... and able to download them ? Or to get them from local disk ? So the steps become : 1 - install a Windows with the last slipstreamed version we have (automated install) 2 - use Windowsupdate until no new update is available (any way to automate ?) 3 - use the magic program 4 - slipstream

• Can I move my Picasa data from one machine to another?

  - by Stuart Hemming

  I have lots of photos stored on an external hard disk. I have Picasa installed on my Windows 7 laptop and have spent a lot of time cataloging the collection, put names to faces and the like. I now have a new machine and I want all the hard work I did on my laptop to be available when I plug my external HD in to the new machine. Is there a magic spell I need to cast to make this happen? Or is all the data I need stored with the photos?

• Late Model 2011 Macbook Pro with SSD appears to be off somehow

  - by chris

  Ok, I just got a SSD for my Macbook Pro Late-2011. The specs from what I read are that the laptop is capable of 6gbps, so I got myself a OZC Agility 240gb 6gbps SSD. Decided to join the club and speed test it with Blackmagic Disk Speed Test.. and the results are equivilent to that of a 3gbps setup. So.. I am wondering overall is there a configuration setting somewhere I can tweak? The original HD was a 500gb HDD the spinning kind. So I'm figuring maybe thats why there may be a setting somewhere hidden I dunno about that I can tweak, just wanna see if anyone else knows if this is the case. edit should also mention did a fresh factory install, nothing carried over from original hd

• if a usb pen drive has 64349 cylinders, is it damaged?

  - by Andrew S

  I have a 4Gb USB pen drive that I'm trying to format with FAT32. When I run fdisk, it gives me this message: The number of cylinders for this disk is set to 64349. There is nothing wrong with that, but this is larger than 1024, and could in certain setups cause problems with: 1) software that runs at boot time (e.g., old versions of LILO) 2) booting and partitioning software from other OSs (e.g., DOS FDISK, OS/2 FDISK) I've tried deleting the partition table, creating new partitions, etc, but they never work. Sometimes I can write to the drive the first time I use it after formatting it, but then it becomes read-only in both Windows and Linux. I've tried this on multiple computers. Am I doing something wrong, or is the drive reporting an incorrect number of cylinders? Is the drive itself likely to be corrupted, and is there anyway to fix this under Windows Vista or Linux? Thanks

• FreeBSD 9 (amd64) reboot/shutdown process is very slow

  - by nbari

  I have a Dell Poweredge 2900 III with FreeBSD 9 (amd64), the server uses mfi wich handles a raid10, I had to reboot the server, but notice that either when rebooting or shutting down the server, something is going wrong, besides taking to much time to reboot/shutdown, after rebooting I notice that that some ldap instances within some jails could'nt start and this was because the database was corrupted. This make me think that probably something was wrong with the disks or mfi card, but checking the disk array / logs everything seems to be working fine. My set up is something like this: Host server has the minimum base of FreeBSD 9 amd64, within I create some jails, the ones contain services like mysql, email, and some others ldap. With FreeBSD 7 and 8 I didn't notice this behavior but with FreeBSD 9 something is not working well. I did a clean installation of FreeBSD 9 and root filesystem is using ZFS. Attached is an image hoping some one can give me a hint of what to check or any kind of advice. reboot capture screen image

• Computer hanged in the middle of bios flashing process

  - by Stalker

  I have a laptop: Toshiba Satellite c660-17j, today I decided to update BIOS. I've downloaded bios updater from manufacturer's web site, and in the middle of flashing process computer hanged. I was waiting more than 30 minutes, but nothing was changed on the screen, i've tryed to PRESS MORE BUTTONS, but there were no reactions, so i've turned it off by removing battery (all other methods failed, even pressing power button for ~10 secs). After that computer can't start. I understand, that there's MESS in BIOS chip, and it's possible to re-flash it with hardware programmer, but I don't have it. I remember, that on some PCs (even on my eeepc) there was possibility to re-flash bios by inserting usb flash-disk (with .dat file on it, which contained BIOS), and power on PC, while holding some keys combination, then PC was switching to BIOS programming mode and re-flashed BIOS, after that it was possible to boot up normaly. Is there a way to recover computer without hardware programming BIOS chip? p.s. sorry for my english.

• ASP Fails with 500 Error

  - by VinceM

  We have a server setup as an IIS box and have some static pages with a few asp pages that handle the form submissions. The asp is really vbscript that sends a CDO message. When moving these pages to the new server the form will not submit, it gives a 500 error and the following shows in Event Viewer: Error: The Template Persistent Cache initialization failed for Application Pool 'DefaultAppPool' because of the following error: Could not create a Disk Cache Sub-directory for the Application Pool. The data may have additional error codes.. I can't seem to find any info on this anywhere... I was thinking it may have something to do with the fact that we created this server from an image of another server. Thanks for your help in advance... Vince

• Ubuntu not showing hard drive

  - by ojek

  I have a laptop which had a broken installation of Windows 7 installed on it. I created a Ubuntu live USB and tried installing Ubuntu over that Windows 7. After a few minutes, I got an error message, so I needed to restart the computer. Now the laptop says that there is no bootable device - reasonable message given that there was an error during Linux installation. However: BIOS can see my hard drive, When I start Ubuntu in live mode, and try either sudo fdisk -l or gparted, it doesn't show any hard disk drives. I am 90% sure that the hard drive is broken, but it is weird that BIOS can see it, and Ubuntu doesn't. How can I be 100% sure about that hard drive? Is there any additional way of detecting my hard drive from Ubuntu?

• Linux mdadm software RAID 6 - does it support bit corruption recovery?

  - by user101203

  Wikipedia says "RAID 2 is the only standard RAID level, other than some implementations of RAID 6, which can automatically recover accurate data from single-bit corruption in data." Does anyone know if the RAID 6 mdadm implementation in Linux is one such implementation that can automatically detect and recover from single-bit data corruption. This pertains to CentOS / Red Hat 6 if those are different from other versions. I tried searching online but didn't have much luck. With SATA error rates being 1 in 1E14 bits, and a 2TB SATA disk containing 1.6E13 bits, this is especially relevant to preventing data corruption. Thanks!

• xl create doesn't bring up console

  - by ineff

  I've tryed to run VM in Xen 4.2 using xl command (for what I get this should be standard toolstack, while xm is deprecated). In this case I've the following configuration file kernel = '/media/home_separata/domU_kernel/boot/vmlinuz-linux' ramdisk = '/media/home_separata/domU_kernel/boot/initramfs-linux.img' name = "domU_Arch_linux" memory = "512" root = '/dev/xvda1 ro' disk = ['file:/media/home_separata/domU_kernel/arch_linux_kernel.img,xvda1,w'] vif = ['mac=aa:::10:11:f1,ip=192.168.0.2,bridge=xenbr0'] when I try to start the virtual machine with xl create it seems it works (it also bring up the vif interfaces) but if I try to connect via xl console it gives an error: xenconsole: Could not read tty from store: No such file or directory the fun fact is that the I've the problem inverse using xend/xm (in that case xend doesn't bring up vif interfaces but activate console). Does anyone have any suggestion?

• Web & SQL Hosting 32 vs. 16 GB of ram

  - by TravisK

  I'm in the market for a new dedicated host for my website. My question is I can pay more to upgrade to 32GB of RAM, but it seems overkill for my website right now, in fact, 16GB seems a little overkill. However, I run a lot of pretty intense full text searches for my site. I'm wondering if SQL Server would benefit, or could it be configured to use the 32 GB of RAM if I purchase the additional to help speed things up? I am assuming that most of my latency is caused by disk I/O and that for the extra money spent on RAM, I might not see any improvement in overall speed?

• Best usb storage for my router, Asus RT-AC66U?

  - by Jason94

  I have the ASUS RT-AC66U and I want to add a USB storage to it. It has 2x USB, and Im already using one for my printer. So the last one I want to use to attach a USB storage, and I've read some reviews stating the throughput of the USB could be up to 18 mb/s. So in regard of USB storage, should I care about hard disk cache? Simple powered-over-usb seems to have 8 mb cache, other (externally powered) has 16 for instance.

• How to choose my own filename format for subscribed podcast files?

  - by user14068

  I subscribe to several podcasts where the filenames of the downloaded mp3 files have no particular pattern to them. When I copy the directory of accumulated mp3 files into my mp3 player, the files play in alphabetical order. What I really want is to play the files chronologically by release date. I currently use iTunes on Windows XP to download the files. What I do now is manually rename the files, adding the date in YYYYMMDD format to the start of each filename so that an alphabetical listing of files will correspond to their chronological order when I listen to them later in PocketTunes on my Palm Centro. Is there some way to get the release date into the filename automatically? If so, I could automate or possibly skip the file renaming step. I would switch from iTunes to something else if that would solve my problem. The file creation time on my local disk isn't a reliable indicator because sometimes I download a few days worth of content at one time, and the files don't necessarily get downloaded in chronological order.

• Why does my drive show as 180GB used, but copies only 40GB?

  - by Manuel

  My computer crashed, so I removed the drive (with Windows XP Professional 32-Bit) and put this drive in another computer running Windows 7 64-bit. Booting with Win7, when going to My Computer it is showing the XP drive as more than 180GB used. So as a quick backup, I'm trying to copy all the disk's content to a folder, but when I start copying, it's showing only 40 GB as the total size of the files to copy. I enabled showing system and hidden files in View options. What could be the problem?

• Mounting share over VPN

  - by user1337

  I have a CentOS 5 web server which currently mounts a NFS export on my Mac OS X 10.7 laptop. It works great, except over VPN I can't get it to mount at all. I tried SMBUp but haven't been able to get it working even locally. It doesn't look like there's an easy way to install netatalk for CentOS 5. Even still, I'm not sure if that's the best way to do it. I tried using a GUI SSH client that can "mount a FTP disk" and it would work, except the files require root access and there's no external root access and the client can't elevate permissions. The basic thing I need to do is have the server be able to read the files off of my laptop, connected via VPN. The files are frequently updated (every 5-20 seconds) so I don't want to manually do that via SSH. Which protocol can work with both platforms and easily handle the latency introduced by VPN (and potentially mobile broadband)? Thanks
