  • Disk boot failure, insert system disk and press Enter.

    - by torbengb
    Similar to this related question, I came home and found that my media center pc showed this message, Disk boot failure, insert system disk and press Enter Before I do anything with the (defective?) harddisk, what are the best first steps I can take to fix this with a minimum of damage? Normally the machine (Win Vista) is always on and never reboots by itself (Windows auto-updates are disabled too). Something must have caused it to reboot, though I'm sure we didn't have a power outage. The machine can't reboot on that disk, but it will boot on another disk I just plugged in for testing. I haven't changed anything, or even touched the machine, for several days, and it has been running fine until now. I did replace the power supply some weeks ago, because the old one suddenly stopped working. It has been working fine with the replacement PSU.

  • Cleaning up temp files in OSX

    - by deddebme
    I was a Windows person for more than 10 years. Around 4 months ago, I switched to Mac, and I have never looked back. But there is one thing that bothers me, which is my Mac partition volume is losing space slowly and gradually. I am pretty sure there are a lot of orphaned temporary files laying around in the volume. I know where to find the obsoleted temp files in my Windows partition, how about in Mac OSX?

  • GNU/Linux: SAS-disk detected as /dev/sg7 - not as /dev/sdb

    - by Ole Tange
    I have just installed a SAS disk into a Debian server. It was detected correctly and everything was fine. Then I moved the SAS disk to a different Debian server, the same hardware model and running same version of Debian, but here the SAS disk is detected as /dev/sg7 and not /dev/sdb. smartctl -a /dev/sg7 works fine, but fdisk and cat hang. I tried putting the SAS disk in another slot: Same problem. How can I force the SAS disk to be detected as /dev/sdb? # uname -a Linux maxwell 3.2.0-4-amd64 #1 SMP Debian 3.2.41-2+deb7u2 x86_64 GNU/Linux

  • My Western Digital 500GB Passport disk says "not formatted" when I plug it in Windows

    - by learnerforever
    Hi, When I plug my Western Digital 500 GB Passport disk in my Windows machine, it says "not formatted, do you want to format it" something. I started having this problem after I put it in an old desktop at home. I don't exactly know what went wrong. May be partition table is corrupted etc. Questions: Some quick search on internet tells me there are partition fixing utilities, which can fix corrupted partition table. testdisk being one of such utiities. I can understand how to use this to copy files from the disk to some other location, but I would like to fix the partition table in-place so that I don't have to temporary move around my data of approx size 300GB, then format passport disk and then again bring back the data. Is there any way I can fix the partition table in-place? Also, how to know which file system was there originally in the disk? Can I only keep the same file system? My current laptop is running Windows 7. Earlier I used to use Windows Vista. My other laptop has Windows XP. So I have access to Windows 7 and Windows XP. Please help! Thanks,

  • Hardware issue: UI freezes and hard drive light goes solid several times per hour

    - by alchemical
    I have a workstation that has been acting up for the last few weeks. It currently has Windows Server 2008 R2 installed on it, and 2 HDD mirrored. A few times per hour the screen will freeze up, applications will say "not responding", sometimes the screen will turn a lighter shaded color--at the same time the HDD light is on solid. This lasts anywhere from 10 to about 50 seconds. Could this be something with one of the drives or the mechanism keeping the mirror in place? Any other ideas?

  • Is it possible to mount a disk image, created with dd, to a directory on a mounted external usb hdd?

    - by Keeper Hood
    I have an image of my home (/dev/sda3) partition, which I've created using the "dd" command. dd if=/dev/sda3 of=/path/to/disk.img I've deleted the home partition via gparted in order to enlarge my /dev/root partition. Then I've recreated the /dev/sda3 partition which is smaller in size then the one I've backed up to the image. I was wondering since I have a 2TB external HDD, could it be possible to mount my backed up image on the external HDD and then copy the files into the /home directory. Since the external HDD would be already in a "mounted state", I'm unsure whether this is a good idea, mounting on a mounted device. I'm running Slackware 13.37 (64bit). used ext4 on all the partitions. resized the root partition with gparted live cd. I've tried mount -t ext4 /path/to/disk.img /mng/image -o loop It gave me an fs error (wrong fs type, bad option, bad superblock on dev/loop/0) Then i did dmesg | tail which outputs: EXT4-fs (loop0) : bad geometry: block count 29009610 exceeds size of defice (1679229 blocks) I have no idea what to do, I want to restore my /home data from the image I've backed up.

  • Can't restore HDD using multiple programs

    - by jonney
    Please refer to my original question about this issue. I tried GetDataBack and it doesn't seem to scan or do anything. I chose the default settings from the first screen and then on step 1 I chose my HDD that's damaged. In step 2, nothing happens. It doesn't scan or do anythong, and on step 3 it doesn't display any of my files. I have also tried TestDisk and what happens in TestDisk is that when I try to fix and rebuild the MFT, it says this: MFT and MFT mirror are bad. Failed to repair them. Here is the status of that HDD under Testdrive: I also tried this app and got no results when I tried to recover the files. I keep getting this error: Last but not least, I tried Recuva and that simply says it's unable to read the MFT. Any suggestions? I have tried various apps already and none of them seems to work.

  • How to transfer Windows Vista disk image to new machine

    - by Mike Hobbs
    I'm trying to upgrade a user's machine to some better hardware. I know of Easy Transfer, but I'd rather not have to reinstall all the programs that are already present. (Some of which are no longer available, anyway). Instead, I'm trying to transfer the entire disk image from one machine to the other, but I ran into issues. If I copy the partition image over to the new machine using Clonezilla, I get errors on boot saying that I need to insert the Vista install disk and run repair. I do that, but it then says that it is unable to repair whatever it is that's broken. Next, I tried to sysprep the old machine before creating the image, but sysprep fails saying that it encountered some sort of system error. Should it be possible to sysprep any arbitrary machine, or does it only work on a relatively clean install? Could it be a missing driver that is tripping me up? The new machine is a fairly stock desktop that shouldn't need any special drivers beyond what's already present in standard Vista. Are there any foolproof methods for doing this sort of thing?

  • Laptop will not boot

    - by WillumMaguire
    This is a dell studio 1558 laptop. Now, something is wrong with the charger that it won't charge the laptop, but the laptop can turn on and operate properly as long as it is attached. It has been like this for a while, but it's not the problem. My problem is that as of yesterday, It takes several minutes to get past the "dell" startup logo (where is says "f2 setup" and "f12 boot options"). After it gets past, it beeps as normal to tell me about the charger and gives me the f2/f12 options and f1 to continue as normal. I can press f12 to get into boot options and load into my live USB BackTrack 5 ISO, but after "startx" it just stays at a black screen. I can also access BIOS setup, but see nothing that would help the problem. When I boot to the HDD, it gives me this Intel UNDI, PXE-2.1 (build 083) Realktek PCIe GBE Family Controller Series V.2.29 (06/30/09) PXE-E61: Media test failure, check cable PXE-M0F: Exiting PXE ROM Operating System not found Also, pressing f8 gives me the same results as booting as normal. It is running Windows 7 Ultimate, dual-core Intel i3 @ 2.27ghz and 4gb RAM. I think there is an issue with the HDD, as the "Operating System not found" would lead me to believe. Is this a fixable problem?

  • Why does storage's performance change at various queue depths?

    - by Mxx
    I'm in the market for a storage upgrade for our servers. I'm looking at benchmarks of various PCIe SSD devices and in comparisons I see that IOPS change at various queue depths. How can that be and why is that happening? The way I understand things is: I have a device with maximum (theoretical) of 100k IOPS. If my workload consistently produces 100,001 IOPS, I'll have a queue depth of 1, am I correct? However, from what I see in benchmarks some devices run slower at lower queue depths, then speedup at depth of 4-64 and then slow down again at even larger depths. Isn't queue depths a property of OS(or perhaps storage controller), so why would that affect IOPS?

  • Windows 7 System process reading/writing like crazy

    - by Mats Ekberg
    I have a problem that my windows 7 computer sometimes starts accessing the disk like crazy for maybe 10 minutes at a time. The process in question is the "system" process. I have disabled superfetch and hibernation on my computer, if that makes any difference. I disabled those to see if they were the cause of the problems, but no change. I have 6 GB of RAM and only the web browser was started when I took the screenshot, so I don't think it was thrashing due to page faults. Any ideas on how to find the cause of this?

So Im searching and asking for starting point to create basic linux distro but not from scratch like LFS but make linux distro based on debian for example. I used debootstrap but still it is 150M large.

  • Installing Windows 7 upgrade version on a clean disk

    - by BobMarley
    Is it possible to install the much cheaper Windows 7 upgrade version on a clean disk? What information will I need? 1) Will the Windows 7 installer ask me for my XP license key? or 2) Will the Windows 7 installer only run if it can detect an existing XP installation? Furthermore, what will happen if my disk crashes and I need to reinstall in the future? Will I need my XP license key again?

  • Lost HDD partition to clean command, testdisk unresponsive

    - by Sujay Anjankar
    I accidentally cleaned my external HDD by the clean command in Diskpart and got a full sized heart attack after that. I did some research and I have tried a number of tools already. To name a few: Testdisk Recuva Partition Find and mount Eassos Recovery I have even tried some other dumb sounding tools, but none of them could find the lost partition. They just show "no partition found". Testdisk shows Partition sector doesn't have the endmark 0xAA55. The file recovery softwares list the files, but none of them seem to be able to restore the lost partition. I need to recover the disk as it was. Any help would be much appreciated!

  • how to restore files deleted in the Mapping virtual drive

    - by r9r9r9
    I used psubst drive1: drive2:path /P to create the persistent virtual drive, I found that's greate, but when I delete files in those drives, they didn't appeared in the Recycle Bin, so How can I restore them? ex: I used (p)subst K: C:/1 to create the K: driver, then I delete files in the K:, I think it will be better if they are moved to the C:/Recycle Bin but not delete persistently. you can find more detail about psubst here: http://code.google.com/p/psubst/

  • What is the S.M.A.R.T. page?

    - by Mads Skjern
    I've just listened to Steve Gibson talk about his SpinRite software, on the Security Now podcast episode 336 (transscript). At 33:20 he says: I can show and do show on the SMART page that sectors are being relocated and that errors are being corrected. That SMART analysis page sometimes scares people because it shows, wait a minute, this thing says we're correcting so many errors per megabyte. What is this SMART page? 1) Some information saved on the HD by SMART, that I can access with a SMART tool like smartmontools? 2) A page (tab) in his SpinRite software? In any case, can I see, in any way, what sectors are marked as bad, without using SpinRite? Preferably using smartmontools!

  • Rocketfish Driver

    - by darthg8r
    I've got a RocketFish SATA enclosure, model number RF-AHD35. It has a card reader on it. Windows doesn't see the card reader. I figure it's a driver problem. But, I don't have the CD that came with it anymore, nor is it available from their site. As a matter of fact, their site looks like my 8 year old made it. Does anyone have access to this driver?

  • File Saving Sometimes Fails

    - by YellPika
    When I attempt to save files, it sometimes (randomly) fails. In Blender, I sometimes get "Version Backup Failed: File Saved With @". In Visual Studio, building sometimes fails with an error message indicating that the target file/exe cannot be overwritten. If I wait a bit, I can save fine. It's almost as if programs are taking an abnormal amount of time to 'let go' of the files. What could be causing this behaviour? This seems to be caused by Windows Live Mesh monitoring my files, and locking them whenever it uploads the new versions (BAD considering the amount of times I save my files, even redundantly). Any suggestions to work around this behaviour? Should I switch to a better service to sync my files?

  • Diagnosing high CPU waiting

    - by Will
    I have a monitoring server that is running icinga/collectd/graphite with about 50 hosts. I have noticed high load/slugging performance on the box. If you take a look at top, you'll see: Cpu(s): 0.6%us, 0.2%sy, 0.0%ni, 7.6%id, 23.4%wa, 0.0%hi, 0.2%si, 0.0%st Notice the HUGE %wa value, which as far as I know means a network or disk bottleneck. ifconfig shows no dropping packets and there's not a ton of bandwidth going on, so that leaves disk issues, right? There's not a lot of disk writing going on either...iotop is reporting we're only writing a little over 1 MB per second and the RAID tool reports everything is A-OK and write caching is enabled. How do I go about trying to figure out how to fix this? UPDATE: iostat -x output is: avg-cpu: %user %nice %system %iowait %steal %idle 0.62 0.10 0.31 9.65 0.00 89.31 Device: rrqm/s wrqm/s r/s w/s rsec/s wsec/s avgrq-sz avgqu-sz await svctm %util sda 0.21 33.34 83.55 16.54 1599.94 399.07 19.97 43.21 416.98 3.71 37.13
