  • Why is the disk making my motherboard beep?

    - by Mark Ransom
    Whenever I let my PC do heavy disk accesses for a long time, the speaker on the motherboard starts making a continuous chirping sound. Thankfully it doesn't happen often, but it drives me nuts when it does. Anybody know where this sound might be coming from, or have any hints as to how to track it down? Edit: The problem appears to be with the processor, the correlation with disk access was coincidental. Thanks for all the answers.

There is a procedure to follow? My Server is a HP. Regards.

  • Clean install vs disk image

    - by Thanos
    Once a year I am making a clean install on windows, in order to keep my system fast. After posting a question on making a bootable windows usb with exe programs where I was adviced to make a disk image, a new question rose. What is the difference in making a disk image and performing a clean install on windows? Which is better in terms of speed, general performance, value for time and transfering between different computers?

  • Bad disk performance on HP DL360 with Smarty Array P400i RAID controller

    - by sarge
    I have a HP DL360 server with 4x 146GB SAS disks and a Smart Array P400i RAID controller with 256MB cache. The disks are in RAID 5 (3 disks + 1 hot spare). The server is running VMware ESX 3i. The disk write performance is really bad. Here are some numbers: ns1:~# hdparm -tT /dev/sda /dev/sda: Timing cached reads: 3364 MB in 2.00 seconds = 1685.69 MB/sec Timing buffered disk reads: 18 MB in 3.79 seconds = 4.75 MB/sec ns1:~# time sh -c "dd if=/dev/zero of=ddfile bs=8k count=125000 && sync" 125000+0 records in 125000+0 records out 1024000000 bytes (1.0 GB) copied, 282.307 s, 3.6 MB/s real 4m52.003s user 0m2.160s sys 3m10.796s Compared to another server those number are terrible: Dell R200, 2x 500GB SATA disks, PERC raid controller (disks are mirrored). web4:~# hdparm -tT /dev/sda /dev/sda: Timing cached reads: 6584 MB in 2.00 seconds = 3297.79 MB/sec Timing buffered disk reads: 316 MB in 3.02 seconds = 104.79 MB/sec web4:~# time sh -c "dd if=/dev/zero of=ddfile bs=8k count=125000 && sync" 125000+0 records in 125000+0 records out 1024000000 bytes (1.0 GB) copied, 35.2919 s, 29.0 MB/s real 0m36.570s user 0m0.476s sys 0m32.298s The server isn't very loaded and the VMware Infrastructure Client performance monitor is showing 550KBps average read and 1208KBps average write for the last 30 minutes (highest write rate: 6.6MBps). This has been a problem from the start. Any ideas?

  • Windows 7 keeps insisting that it needs to check disk for consistency, but never does

    - by Mike
    Lately Windows 7 has been telling me that I need to check disk D: for consistency. This happens more than 50% of the time when booting up. The first time, I didn't touch anything so that it would go ahead and do its scan. It didn't seem to do anything - just booted straight into Windows. The second time I tried to skip it by pressing any key. It ignored all of my keystrokes and still counted down to 0 (then skipped the disk check). Sometimes, it gets down to 0 but then just hangs... no indication that anything is going on. This is happening on a < 3 month old laptop. C: and D: are on the same physical disk - just two partitions. I never get any notification that C: needs to be checked for consistency. It's a ~300GB HD. C: has 60gb (32gb free) and D: has ~240GB (122gb free). What could be causing this to keep coming up? What can I do to fix it? Thanks!

  • After reinstallation, Disk Cleanup disappears when I click OK.

    - by James
    After I reinstalled Windows 7, Disk Cleanup stopped working. I can start Disk Cleanup and select the drive to clean, but when I click on the OK button, the window disappears. Any solutions? Here's the data from Windows LogsApplication :- EventData 1744235005 1 APPCRASH Not available 0 cleanmgr.exe 6.1.7600.16385 4a5bc5e1 Csi.dll 14.0.4733.1000 4b5662be c0000005 00135213 F:\Users\Jacob\AppData\Local\Temp\WER419.tmp.WERInternalMetadata.xml F:\Users\Jacob\AppData\Local\Microsoft\Windows\WER\ReportArchive\AppCrash_cleanmgr.exe_6514b6ecb633f97cbf78e3a5bcae2c4bd74351_0d3b109c 0 75fa9599-41b1-11e0-b864-001966b2bcb6 0 The above one was with an Information icon.

  • Win 2008 R2 - copying TO disk is very slow, copying FROM is more or less okay

    - by avs099
    I have Windows 2008 R2 SP1 with 4 identical SATA disks (Seagate Barracude 7200) in RAID 5 array. It has 4Gb of memory; all recent updates are installed. Problem: when I copy large file from one folder to another, I get about 10MB/s average speed. When I read this file from network share via 1Gbps connection - I get about 25-30 MB/s. Both numbers seems to be low for me - but specifically I'm very frustrated with low write speed. there is no antivirus, no hyper-v, it's just a fileserver - i when i do my tests nobody else reads/write from it (we have only 4 people in a team, so I'm sure). Not sure if that matters, but there is only 1 logic disk "C" with all available space (1400 GB). I'm not an admin at all, so I have no idea where to look and what other information to provide. I did run performance monitor with "% idle time", "avg bytes read", "avg byte write" - here is the screenshot: I'm not sure why there are such obvious spikes. Any idea? Please let me know if you need me to provide more information - what counters should I check, etc. I'm very eager to get this solved. Thank you. UPDATE: we have another Windows 2008 R2 SP1 server with 2 RAID1 arrays - one is disk C (where windows is installed, another one is disk E). It is running Hyper-V and does not have antivirus. I noticed the following behavior when I copy large file (few GBs): C - C: about 50MB/sec C - E: about 55MB/sec E - E: 8MB/sec!!! E - C: 8MB/sec!!! what could cause this?? E drive is RAID1 array from same Seagate Barracuda 1TB drives..

  • Mac OS X Disk Encryption - Automation

    - by jfm429
    I want to setup a Mac Mini server with an external drive that is encrypted. In Finder, I can use the full-disk encryption option. However, for multiple users, this could become tricky. What I want to do is encrypt the external volume, then set things up so that when the machine boots, the disk is unlocked so that all users can access it. Of course permissions need to be maintained, but that goes without saying. What I'm thinking of doing is setting up a root-level launchd script that runs once on boot and unlocks the disk. The encryption keys would probably be stored in root's keychain. So here's my list of concerns: If I store the encryption keys in the system keychain, then the file in /private/var/db/SystemKey could be used to unlock the keychain if an attacker ever gained physical access to the server. this is bad. If I store the encryption keys in my user keychain, I have to manually run the command with my password. This is undesirable. If I run a launchd script with my user credentials, it will run under my user account but won't have access to the keychain, defeating the purpose. If root has a keychain (does it?) then how would it be decrypted? Would it remain locked until the password was entered (like the user keychain) or would it have the same problem as the system keychain, with keys stored on the drive and accessible with physical access? Assuming all of the above works, I've found diskutil coreStorage unlockVolume which seems to be the appropriate command, but the details of where to store the encryption key is the biggest problem. If the system keychain is not secure enough, and user keychains require a password, what's the best option?

  • Linux disk usage analyser that acts like symlinks are real files

    - by Rory
    I am using git-annex, an extension to the DVCS git, which is designed for handling large files. It makes heavy use of symlinks. The actual large files are moved to the .git/annex directory and the original files are symlinked to there. I am running out of disk space, and need to clear up, and see what's using all my space. Usually I'd use a disk usage tool like ncdu, Baobab or Filelight. However they treat the symlink as essentially empty, and only count the file that it is pointing to as using any space. Which means when I use git-annex, it shows no space used in the main directories and lots of space used in the .git/annex directory. This is not helpful. Is there any (graphical or ncurses) based disk usage programme for linux (apt-get installable would be easie that is capable (through options or not) of counting a symlink as using up the space that the original file uses up? Many have options for different behaviour for hard links, so makes sense that some should h (I know counting symlinks as using space has flaws, like counting the space space twice, broken symlinks, etc. But that's OK for my purposes)

  • How to restore/change Alt+Tab behaviour/ram usage and a few other things after Ubuntu upgrade from 11.04 to 11.10?

    - by fiktor
    I use Ubuntu for programming. I recently updated it from 11.04 to 11.10. There are some things I don't like in the new version of Unity desktop interface. I don't actually know if it is hard to restore previous behavior or not, and if it is not, where should I look to do that. I know a bit of programming, but I really don't know much about Linux settings. I used to have 3-6 terminal windows and switch between them with Alt+Tab and Shift+Alt+Tab. I liked half-transparent terminal windows, since with them I could open web-page with some instruction in Firefox, press Alt+Tab and type commands in a console window, being able to recognize text on a web-page under it. Now I have problems with my usual work-style because of the following. List of "negative" changes Alt+Tab shows just one icon for all console windows. When I wait some time, it, however, shows all windows, but I don't like to wait. I prefer to remember order of windows and press Alt+Tab as many times as I need to switch to the right window. Alt+Shift+Tab to switch in reverse order doesn't work now. Console windows are not transparent any more. When I don't wait, and switch to this icon, it shows all console windows altogether. So even if they were transparent, I wouldn't be able to see anything below them (I can read something only from the window, which is directly under current one, not a few levels under). When I run a few console windows in Unity I had 740Mb used on Ubuntu 11.04, but I have 1050Mb now. The question is how to make it back to 750-. I really need my memory, since I use my computer to work with 1512Mb of data and I try to save every 10Mb possible (if it doesn't take too much of machine and, more importantly, my time). When I press "The Super key" I have a field to type the name of the program I want to run. But now it sometimes shows this field, but when I'm trying to type nothing happens. Probably, focus is not on the right field. I don't really mean to restore exactly the same behavior, but I want to make my work in Ubuntu 11.10 efficient (at least as efficient as in Ubuntu 11.04). I would be happy if there are some ways to accomplish that. What have I tried I have installed CompizConfig Settings Manager. I have read this question. However enabling "Static Application Switcher" makes Alt+Tab crazy: after enabling it It says about key-binding conflicts with "Ubuntu Unity Plugin"; "Alt+Tab" switching doesn't change, but "Shift+Alt+Tab" now works and shows all windows; Memory usage increases. I have tried turning off Ubuntu Unity Plugin, but this doesn't seem right thing to do, since it seems to turn off all menus, a lot of keystrokes and app-launcher, which usually activates with "The Super key". I have found, that window transparency can be enabled by "Opacity, Brightness and Saturation" plugin from Accessibility. However I don't know if enabling it is the right thing to do (at least it increases memory usage). Update: everything solved but #3: see my own answer below. I have made a separate question about issue #3 (transparency).

  • Unable to format disk: 'The system cannot find the file specified'

    - by ACarter
    I have a USB flash drive, which I may have mucked up, so I used DISKPART's CLEAN to clean it up. I created a simple volume, and tried to format it. (This is all using Windows' disk management.) I was told The system cannot find the file specified. So I tried using DISKPART (as an admin): DISKPART select volume 9 Volume 9 is the selected volume. DISKPART format recommended DiskPart has encountered an error: The system cannot find the file specified. See the System Event Log for more information. DISKPART As you can see, no luck. When I plug the drive in, the computer makes a beep noise as though it has recognised something, but nothing appears in My Computer How can I format the disk so I can use it again?

  • How HP D2700 disk enclosure is monitored for alarms via SNMP

    - by VSAC
    We have HP D2700 disk enclosure and we would like to monitor D2700 (connected to HP Proliant DL360G8) for alarms.I have following questions regarding this. What are the options available for reporting D2700 hardware alarms (disk failure, power failure) via SNMP? We understand the D2700 to have an Ethernet interface for controller A and B and alarms are available via SNMP via this interface. Can anyone provide the actual alarms via this interface? (MIB and alarm list) As we have a number of D2700’s and would like to minimize the number of physical connections to the switch and associated IP addresses; Is there a mechanism to monitor the D2700 from the SCSI connected HPDL360 and raise SNMP alarms from the DL360 for hardware failures on the D2700? If so can anyone provide details and the actual alarms and MIB via this mechanism? Thanks!

  • disk-to-disk backup without costly backup redundancy?

    - by AaronLS
    A good backup strategy involves a combination of 1) disconnected backups/snapshots that will not be affected by bugs, viruses, and/or security breaches 2) geographically distributed backups to protect against local disasters 3) testing backups to ensure that they can be restored as needed Generally I take an onsite backup daily, and an offsite backup weekly, and do test restores periodically. In the rare circumstance that I need to restore files, I do some from the local backup. Should a catastrophic event destroy the servers and local backups, then the offsite weekly tape backup would be used to restore the files. I don't need multiple offsite backups with redundancy. I ALREADY HAVE REDUNDANCY THROUGH THE USE OF BOTH LOCAL AND REMOTE BACKUPS. I have recovery blocks and par files with the backups, so I already have protection against a small percentage of corrupt bits. I perform test restores to ensure the backups function properly. Should the remote backups experience a dataloss, I can replace them with one of the local backups. There are historical offsite backups as well, so if a dataloss was not noticed for a few weeks(such as a bug/security breach/virus), the data could be restored from an older backup. By doing this, the only scenario that poses a risk to complete data loss would be one where both the local, remote, and servers all experienced a data loss in the same time period. I'm willing to risk that happening since the odds of that trifecta negligibly small, and the data isn't THAT valuable to me. So I hope I have emphasized that I don't need redundancy in my offsite backups because I have covered all the bases. I know this exact technique is employed by numerous businesses. Of course there are some that take multiple offsite backups, because the data is so incredibly valuable that they don't even want to risk that trifecta disaster, but in the majority of cases the trifecta disaster is an accepted risk. I HAD TO COVER ALL THIS BECAUSE SOME PEOPLE DON'T READ!!! I think I have justified my backup strategy and the majority of businesses who use offsite tape backups do not have any additional redundancy beyond what is mentioned above(recovery blocks, par files, historical snapshots). Now I would like to eliminate the use of tapes for offsite backups, and instead use a backup service. Most however are extremely costly for $/gb/month storage. I don't mind paying for transfer bandwidth, but the cost of storage is way to high. All of them advertise that they maintain backups of the data, and I imagine they use RAID as well. Obviously if you were using them to host servers this would all be necessary, but for my scenario, I am simply replacing my offsite backups with such a service. So there is no need for RAID, and absolutely no value in another layer of backups of backups. My one and only question: "Are there online data-storage/backup services that do not use redundancy or offer backups(backups of my backups) as part of their packages, and thus are more reasonably priced?" NOT my question: "Is this a flawed strategy?" I don't care if you think this is a good strategy or not. I know it pretty standard. Very few people make an extra copy of their offsite backups. They already have local backups that they can use to replace the remote backups if something catastrophic happens at the remote site. Please limit your responses to the question posed. Sorry if I seem a little abrasive, but I had some trolls in my last post who didn't read my requirements nor my question, and were trying to go off answering a totally different question. I made it pretty clear, but didn't try to justify my strategy, because I didn't ask about whether my strategy was justifyable. So I apologize if this was lengthy, as it really didn't need to be, but since there are so many trolls here who try to sidetrack questions by responding without addressing the question at hand.

  • 32bit vs 64bit guest VM and RAM usage

    - by sims
    Why does a 32bit domU (Xen guest VM) use less RAM than a 64bit? Notes: The same software complied for a different arch(AMD64 vs. 686). Obviously this is Linux or BSD or something easily ported. Maybe this is also a good one for SO. I've read this is so. I can guess why, but I'd like to hear everyone's comments.

  • Using DD for disk cloning

    - by roe
    There's been a number of questions regarding disk cloning tools (yes, I did search for it) :) and dd has been suggested at least once. I've already considered using dd myself, mainly because ease of use, and that it's readily available on pretty much all run of the mill bootable linux distributions. To my question, what is the best way to use dd for cloning a disk. I don't have much time to go around, and no test-hardware to play with, so I need to be prepared, and it's pretty much a one-shoot chance to get it done. I did a quick google search, and the first result was an apparent failed attempt. Is there anything I need to do after using dd, i.e. is there anything that CAN'T be read using dd? Thanks!

  • No space left on device with encrypted disk that takes all space

    - by Yosef
    I use Ubuntu 11.04. There's no space left on device. I have encrypted the disk that takes up space (maybe it's good to disable it, but I don't know how). In shell, I get this message: No space left on device I run df -I: Filesystem Inodes IUsed IFree IUse% Mounted on /dev/sda1 3055616 602499 2453117 20% / none 210161 890 209271 1% /dev none 214789 8 214781 1% /dev/shm none 214789 53 214736 1% /var/run none 214789 3 214786 1% /var/lock /home/myuser/.Private 3055616 602499 2453117 20% /home/myuser df -I Edit: When I run only df: Filesystem 1K-blocks Used Available Use% Mounted on /dev/sda1 48060296 45618928 0 100% / none 1538340 684 1537656 1% /dev none 1547596 808 1546788 1% /dev/shm none 1547596 104 1547492 1% /var/run none 1547596 0 1547596 0% /var/lock /home/myuser/.Private 48060296 45618928 0 100% /home/myuser Edit: I thinking about few solution but I don't know which better and how exactly to do them: to enlarge partition size (I cant install gparted - no more disk space) remove encryption of partition - I really not need that

  • Running a Check-Disk (Is it dangerous)

    - by vaccano
    I have a lap top that a friend of mine would like me to fix. It is giving a blue screen on boot up. When I looked up the error message it indicates that I should run a check disk. Is this dangerous? Should I try to off load stuff from the hard drive first? I ask because I had a hard drive of my own that when I ran check disk it wiped a bunch of "bad sectors" and I lost most of the info on it (but it had been going bad). Opinions?

  • Add Mirror for volumes other than the last one in Windows 7 (disk "not up-to-date")

    - by rakslice
    I'm using Windows 7 x64 Ultimate. I have an existing 4TB disk with 3 NTFS volumes, a new 3TB blank disk, and I'm trying to mirror the volumes onto the new disk. My Windows install is on an SSD which is Disk 0. The 4TB disk with volumes is Disk 1, and the new blank disk is Disk 2. I can add a mirror successfully for the last volume, but when I try to add a mirror for the first volume I immediately get errors (see below). Is there something I special I need to do to add a mirror for a volume other than the last one? More info: I opened Disk Management, right-clicked on the first volume on the existing disk, went to Add Mirror, and selected the new disk. The first time I did this I was prompted to convert the new disk to a Dynamic Disk, which I approved. Subsequently I got a message: The operation failed to complete because the Disk Management console view is not up-to-date. Refresh the view by using the refresh task. If the problem persists close the Disk Management console, then restart Disk Management or restart the computer. I've refreshed disk management, restarted the computer, and converted the new disk to basic and back to dynamic, but I still get that error message. Looking around for suggestions of a workaround, I saw a suggestion to use the diskpart command line tool. Running diskpart from the Start Menu as Administrator, I did select volume 2 (the first volume I want to mirror) and then add disk 2 (the new disk), and received a somewhat similar error: Virtual Disk Service error: The disk's extent information is corrupted. DiskPart has referenced an object which is not up-to-date. Refresh the object by using the RESCAN command. If the problem persists exit DiskPart, then restart DiskPart or restart the computer. A rescan appears to be successful: DISKPART> select disk 2 Disk 2 is now the selected disk. DISKPART> rescan Please wait while DiskPart scans your configuration... DiskPart has finished scanning your configuration. but attempting to add the mirror again resulted in the same error. The only similar report I found online was this: http://www.sevenforums.com/hardware-devices/335780-unable-mirror-all-but-last-partition-drive.html Based on that I attempted to mirror the last volume on the disk to the new disk using diskpart, and that started successfully -- it is currently resynchronizing. More Background: In the course of dealing with a failing 3TB hard drive, I bought a replacement 4TB drive and installed it, then copied the partitions from the failing drive to it using Minitool Partition Wizard Home, and then removed the failing drive and was up and running again normally. Now I've received a warranty replacement for the failing drive, and installed it, and now I'm attempting to mirror my partitions to it.
