• Method for imaging a HDD? [closed]

  - by Sonny Ordell

  Possible Duplicate: Imaging new hard drive in Windows 7 laptop? I have to image my 320gb Laptop HDD before I send it in for repairs. The HDD is likely going to get replaced, and I would ideally like to be able to restore everything as I have it now without having to reinstall my OSes, programs and place all my files back again. I can make space on an external HDD I have, so am just looking for how I should go about this. Should I just use dd with a linux rescue cd? Or is there perhaps a more suitable program with its own rescue disk?

• Is there a way to determine the original size or file count of a 7-zip archive?

  - by Zac B

  I know that when I compress an archive with the 7za utility, it gives me stats like the number of files processed and the amount of bytes processed (the original size of the data). Is it possible, using the commandline (on linux) or some programming language, to determine: the original size of an archive, before it was compressed? the number of files/directories contained within an archive? The answer might be "no, just decompress the whole archive and do counting/sizing then", but it would be useful to know if there was a faster/less space-greedy way.

• Data drive disappearing.

  - by Mike Keller

  We have a Windows 2003 R2 server with SP 2 here that randomly loses a partition. There are two partitions the C: and the D: (the one that disappears). When I go into Disk Management the space shows available on the drive but that it isn't formated. There are two drives that are set up in a RAID 1 array. There isn't anything sticking out in the event log as to something triggering this problem and thank god we do daily backups of the data, but it gets kind of annoying to have to go back in there and reformat the partition and restore the data. Any places I can poke around to find the cause of this or even better solutions to the problem would be appreciated.

• What is better to have more LUNs or more Storages

  - by skomak

  Hi, what is better to have - more LUNs or more Storages. Actually i have 1 storage ESXi per 1 LUN so there are about 15 LUNs and 15 storages. Now there is a kind of problem because the LUNs have different space allocated so if i remove 2 LUNs f.e. 1 2 3 4 [x] 6 [x] 8 9 (like that) i can't make 1 LUN from 5 and 7 pieces of free diskspace on IBM storage array. It's a first argument to not have a lot of LUNs. If i had to make only a few LUNs (about 3) and inside some Storage from ESXi would it be a better idea? For example for expanding storage capacity? i look for good solutions. Thanks in advance.

• Good 1U Rack Firewall

  - by AX1

  Hello, I'm trying to find a good 1U rack firewall at a reasonable price. Most pricing is completely out of space (thousands of dollars? Why?). I don't want to list all features I need/want (there are too many variations but I don't care about most of them) - I'm just looking for something simple and not overly expensive. I've looked at the WatchGuard XTM 505 which is more reasonably priced -- are there any other firewalls in that range or even less expensive that are good for a small company?

• windows server backup 2008 R2 - what is generating all the change data?

  - by bobjandal

  We have a small relatively idle windows server 2008 R2 installation that does basic filesharing and exchange for about 10 not very active users. When running a windows server backup, the incremental data daily is about 20GB. This is not coming from users shared files, nor from changes in their mailbox sizes. The total size of the installation is 249GB, which is mostly old files. Where is all this data coming from, and how can I reduce it ? Using online backup of the vhd file from the backup is taking a while because of this daily change. Is there some way I can at least see what files are changing and contributing to this data ? Options I can think of but am not sure about: 1) pagefile churning - altho the backup does not include the pagefile, perhaps the changed blocks left behind are included ? 2) logs or something ? but the installation size stays the same every day 3) should I zero free space using sdelete before backing up perhaps ?

• Why does a Windows 7 installation grow so seriously and how to shring it?

  - by Ivan

  I store all my data and the most of applications (those legally available in "portable" versions) on drive D: and only use drive C: for the Windows system and some heavily integrated applications like MS Office, Visual Studio, Adobe Reader, Flash Player etc. When I was using Windows XP, 50 GiB drive C: was more than enough. Now, as I've mitigated to Windows 7, it hardly is. Yesterday as I've checked, 7 GiBs were free on drive C:. Then I've installed fresh Windows updates (which were just some tens of MiBs to download) and checked again: now there are only 2 GiBs free. Where have 5 GiBs gone? PS: Don't be surprised my system installation takes actually that much: I've got Visual Studio and SQL Server with complete offline documentation library, but that doesn't explain where does free space disappear on simple Windows updates. PPS: I use an augmented CCleaner version to clean my PC every day, so there are for sure no temporary internet files of recycle bin trash files taking the place.

• graph performance monitor windows and linux

  - by Patrik

  We are using Munin to get graphs of our servers. (such as CPU load, I/O, available disk space, etc. ) Munin gives us last 24h, last 7 days, last month and last year. The good thing with Munin is that it supports all kinds of clients, such as Windows, Linux and switches because it can monitor over SNMP. However, we have a problem with the Munin client for Windows. Since we upgraded to Windows Server 2008 R2 it won't show graphs for some performance counters. What options are there out there? Both free and commercial.

• Vertical alignment problem in textbox in Microsoft Word 2007

  - by Surjya Narayana Padhi

  I pardon as its not a programming question at all. But if anybody can answer this it will be usefull for me. In MS word 2007 I drew a textbox and entered some text. Then I right clicked on textbox and went to format shape Then went to TextBox tab and reduced the top internal margin to 0.1 cm. But still it seems there is too much space at the top inside the textbox. I am not able to position the text exactly at the vertical middle of textbox. If I choose the auto-rezide option in format Shape, the textBox size is increases automatically but the text remains exactly at vertical and horizontal middle of textbox. but anyhow I need the textbox to be small. This is very minor but annoying problem. Can anybody help?

• Strip X Window System from OpenRD (Fedora core 8)

  - by disown

  I just got myself an OpenRD Client embedded box with an old Fedora 8 on it. Runs like a charm, only problem is that the default install has X on it, which I would like to remove in order to free up some space. I found a similar post here on the same topic, but yum groupremove doesn't work in my case, yum grouplist returns nothing, so I presume that no groups are defined. I don't know if this is because fedora 8 didn't have any groups, or because the OpenRD build is special in some way. In any case, I would like some tips on which package(s) to remove in order to remove an as big chunk of X as possible. Thanks in advance.

• Increasing a Linux partition once VM size increased in vSphere?

  - by dannymcc

  I have a Ubuntu 12.04 VM running on VMWares ESXi 5.1. The server (VM) itself has run out of space, the results of df -h are as follows: Filesystem Size Used Avail Use% Mounted on /dev/sda1 19G 17G 1.2G 94% / udev 490M 4.0K 490M 1% /dev tmpfs 200M 232K 199M 1% /run none 5.0M 0 5.0M 0% /run/lock none 498M 0 498M 0% /run/shm The original VM HDD size was just under 19GB which is I have now increased to 100GB within the vCenter GUI: Is there a simple way of doing this? The VM doesn't seem to acknowledge the increase at all.

• How can I check whether a volume is mounted where it is supposed to be using Python?

  - by Ben Hymers

  I've got a backup script written in Python which creates the destination directory before copying the source directory to it. I've configured it to use /external-backup as the destination, which is where I mount an external hard drive. I just ran the script without the hard drive being turned on (or being mounted) and found that it was working as normal, albeit making a backup on the internal hard drive, which has nowhere near enough space to back itself up. My question is: how can I check whether the volume is mounted in the right place before writing to it? If I can detect that /external-backup isn't mounted, I can prevent writing to it. The bonus question is why was this allowed, when the OS knows that directory is supposed to live on another device, and what would happen to the data (on the internal hard drive) should I later mount that device (the external hard drive)? Clearly there can't be two copies on different devices at the same path! Thanks in advance!

• How to partition hard drive that has no os installed?

  - by Sarang Patil

  I have 500 GB hard drive. The laptop came with windows 7 pre installed in it. Now as I am installing Windows 8, I have deleted the C drive. So I have 460 GB free unused space where I can install Windows 8. But the Windows 8 installer does not give me any option to partition the 460 GB. The only option available are "Refresh" and "Load driver" or just selecting the 460 GB HDD and installing Windows 8 in it. So how can I partition this 460 GB before I install Windows 8 in it? Edit: Can you suggest me some tools that partition the hard drive and RUN independently (as I do not have any OS installed) from a USB ?

• Trigger ZFS dedup one-off scan/rededup

  - by Jake Wharton

  I have a ZFS filesystems which has been running for some time and I recently had the opportunity to upgrade it (finally!) to the latest ZSF version. Our data doesn't scream dedup but I firmly believe based on small tests that we could gain anywhere from 5-10% of our space back for free by utilizing it. I have enabled dedup on the filesystem and new files are slowly being dedupified but the majority (95%+) of our data already exists on the filesystem. Short of moving the data off-pool and then recopying it back, is there any way to trigger a dedup scan of existing data? It doesn't have to be asynchronous or live. (And FYI there isn't enough room on the pool to copy the entire filesystem to another and then just switch the mounts.)

• Running Mathimatica-5 remotely

  - by oxinabox.ucc.asn.au

  Ok, I have Mathmatica 5 - a powerful CAS. I have a cheap netbook, wich not olny is too slow to run mathmatica on, I doubt it has the harddrive space. I do however have remote access to a number of very powerful computers, (most of wich run variose linuxes, but one of which is windows server 2008) Mostly over SSH but other protocols can be arraged for some, i'm sure. (I might even be able to remote desktop the windows server 2008) So I'ld like to install Mathmatica onto one of these machine and then run it remotely. Either from the command line via putty or via some other method. I glanced through the mathmatical documentaion and read soemthing about using some MathLink program, wich linkes the front end istalled on my computer to a remote kernal. Anyone have any expirience with this? I'm not sure if this belongs here or in SuperUser.

• How to allow an internal server accept remote connections not through RD Gateway

  - by Matt Ahrens

  So, I help administrate a collection of servers running various windows server environments. We have a RD Gateway server, properly configured, to gatekeep for us. It does not have the other servers listed in it's server farm category, though. I just added a refurbished server for a non-profit development environment that is sharing the rack space and port. I would like this server to be accessible via remote connection, but not require RD gateway certification (I cannot add the users for this development server to our gateway since they do not work for the organization hosting the rack.) Is there any way for me to add this dev. server as an exception to which servers should require RD Gateway clearance, or otherwise let users bypass RD gateway credentials for this one machine? Thanks, and let me know if I am misinformed on how RD gateway works or anything. I am still learning.

• Outlook 2010: Cached Exchange Mode, File Storage and Security

  - by dangowans

  I'm in an environment where profile space is a premium, and most users have "frozen" machines, meaning that on restart, the C: drive is returned to its original state. Cached Exchange Mode sounds interesting to me, but I'm wondering if we can take advantage of it without causing other issues. Where in the file system does the cached data get stored? Is it in the profile? A temp folder? Is the cached file secured in some way to keep others from seeing it?

• Looking for a sketch program with an infinite canvas

  - by Nils Riedemann

  Hi there, I'm not quite sure if such questions are allowed on SU. I was just wondering whether there is a sketch program like Adobe Ideas for iPad that has an infinite canvas but for OSX. It need not be feature rich and all that. Very simple, just for sketching out some stuff without thinking about the space. I was thinking about some vector tool where I could infinitely zoom in and draw. I'm sure you get the idea of what I am looking for. Any hints? OS is OS X.

• Can't run Ubuntu from disc

  - by alex

  When I place the boot CD in my CD drive and boot from it, I get the Ubuntu menu. I have these options Try Ubuntu without any change to your computer Install Ubuntu Check disc for defects Test memory Boot from first hard disk I can use the cursor keys to select them, and I can push F1 for help etc. However, I can not select an option. I've highlighted the first and tried enter, space bar etc. I do have a KVM, so I plugged in a 2nd USB keyboard and tried it but no go either. I can push escape and then got to the prompt. Am I doing something wrong?

• Disabling the command enter shortcut on Mac Entourage.

  - by Bruce

  It seems like disabling a shortcut should not be such a big deal, but I cannot seem to be able to do it for any shortcuts and specifically not for the combination that I keep hitting by mistake, every single day. The smaller space bar makes it very easy to hit the command key by mistake, and the return is a commonly used key when typing. I keep sending important e-mails before I am done typing, or worse, before I am done editing. I do not necessarily want to disable all the shortcuts, but that one for sure. The choices for changing anything in Entourage seem very limited. [Entourage for Mac 2008. Version 12.2.8. (101117) ESD] It is easy enough just to hit "send." This short cut causes a lot more trouble than it saves. Help.

• GRUB Error after Deleting Linux Partition

  - by Nironan12

  I was dual-booting with Windows 7 and Windows Vista each taking up half of my hard drive. In Windows 7 I used Easeus Partition Manager to shrink my Windows 7 volume 8GB. On the unallocated space, I installed Linux Mint 8 RC1. After a little bit of playing around with it, I booted in Windows 7, used EPM again and deleted the 8GB Linux partition. I then extended Windows 7 on the 8GB. After restarting my computer, all I get is a black screen and this: GRUB loading. error: no such partition grub rescue> I do not have a Windows 7 disk nor does my computer come with Startup Repair. What do I do?

• Hyperic HQ says the server is down, but it is not!

  - by Diego Jancic

  Hi, I've been using HQ for a couple months now, and everything worked fine. But since yesterday all resources go down for a couple hours, and then everything restores to normal, and then go down again without doing anything. The server of course is working, the HQ server and agent are both working, and the IPs were not modified. I've tried to re-run the setup in the HQ agent, and it did not change anything. Agent is in Windows 2008, and Server is in Windows 2003. I'm using HQ Version 4.1.2 (build #1053 - May 06, 2009 - Release Build) Any hint? Thanks! Update: I guess (although I'm not sure) it stopped working when the disk on the server went full, with 0 bytes of free space. Of course I've freed more than 15gbs and restarted the HQ server/database.

• Need advice on which PCI SATA Controller Card to Purchase

  - by Matt1776

  I have a major issue with the build of a machine I am trying to get up and running. My goal is to create a file server that will service the needs of my software development, personal media storage and streaming/media server needs, as well as provide a strong platform for backing up all this data in a routine, cron-job oriented German efficiency sort of way. The issue is a simple one - all my drives are SATA drives and my motherboard controller only contains 4 ports. Solving the issue has proven to be an unmitigated nightmare. I would like advice on the purchase of the following: 4 Port internal SATA / 2 Port external eSATA PCI SATA Controller Card that has the following features and/or advantages: It must function. If I plug it in and attach drives, I expect my system to still make it to the Operating System login screen. It must function on CentOS, and I mean it must function WELL and with MINIMAL hassle. If hassle is unavoidable, there shall be CLEAR CUT and EASY TO FOLLOW instructions on how to install drivers and other supporting software. I do not need nor want fakeRAID - I will be setting up any RAID configurations from within the operating system. Now, if I am able to find such a mythical device, I would be eternally grateful to whomever would be able to point me in the right direction, a direction which I assume will be paved with yellow bricks. I am prepared to pay a considerable sum of money (as SATA controller cards go) and so paying anywhere between 60 to 120 dollars will not be an issue whatsoever. Does such a magical device exist? The following link shows an "example" of the type of thing I am looking for, however, I have no way of verifying that once I plug this baby in that my system will still continue to function once I've attached the drives, or that once I've made it to the OS, I will be able to install whatever drivers or software programs I need to make it work with relative ease. It doesn't have to be dog-shit simple, but it cannot involve kernels or brain surgery. http://www.amazon.com/gp/product/B00552PLN4/ref=pd_lpo_k2_dp_sr_1?pf_rd_p=486539851&pf_rd_s=lpo-top-stripe-1&pf_rd_t=201&pf_rd_i=B003GSGMPU&pf_rd_m=ATVPDKIKX0DER&pf_rd_r=1HJG60XTZFJ48Z173HKY So does anyone have a suggestion regarding the subject I am asking about? PCI SATA Controller Cards? It would help if you've had experience with the component before - that is after all why I am asking here - for those who have had experience that I do not have. Bear in mind that this is for a home setup and that I do not have a company credit card. I have a budget with a 'relative' upper limit of about $150.00.

• How to delete old pagefile.sys and hiberfile.sys on secondary disk (old windows install)

  - by Silvermist

  A while ago I swapped my main hard disk for a SSD. Now the old one is used as a secondary hard disk, and my OS is a fresh windows install on the main SSD disk. Nevertheless, there are still huge pagefile.sys and hiberfile.sys on that secondary hard drive. Those are not the ones used by the current windows, as those do exist on C:. I tried to attrib -s -h them, but it refused with "Access denied". Any idea how to delete those old unused system files and reclaim the space?
