  • How do I restore a partition without losing the data?

    - by sama
    I lost the D-partition in My Computer I opened My Computer, but couldn't find it and I don't know where it is or how to return it. I went to Disk Management and found it available as free space. So I tried to make it NTFS, but I had to format the drive and I don't want to, since it will erase my data. Does anyone know how I can restore my partition without losing my data?

  • Ubuntu on an XPS 14 Ultrabook with mSATA cache and 500GB HD - how to partition for dual boot?

    - by JDS
    I am getting an XPS 14 ( http://www.dell.com/us/p/xps-14-l421x/pd ) and I want to dual-boot Windows and Ubuntu. This thing has a 500GB standard HD and a 32GB mSATA that can be used as cache. Does anyone know how this thing is partitioned? Is the OS installed on the mSATA drive and data is on the big HD? Is there a BIOS controller or maybe even a Windows driver that makes the mSATA drive and 500GB HD appear contiguous? I get the impression that something makes the mSATA be used invisibly as cache, but I can't find any technical documentation how that works. My primary concern here is wrt dual-booting Ubuntu. I want to know if I need to partition the mSATA separately, or the big HD, or just partition the "magic" contiguous disk space that appears available to the OS.

  • attach two hdds to a computer having 500W smps

    - by Gaurav Sharma
    I have a desktop system installed with a 250 GB hdd (seagate sata II) this system is having a power supply of 500W (not sure if it is 650W but not more than that) the power supply is a local brand. Will it be safe to attach a second 250 GB sata II hdd on the same system. Safe in the sense that the system may not fall short of power at any time. My system's config is as follows Core2Duo processor Mercury cabinet having an additional fan (small one) sata dvd writer 52X windows xp sp 2 ASUS motherboard (intel G965 express chipset) If the above specified power supply is not sufficient for above configuration of system then please suggest the appropriate power supply (including watts)

  • Windows 7: Moving Program Files location during install using unattend.xml

    - by Shevek
    I am planning on using an unattend.xml to create a Windows 7 Ultimate 64-bit setup with Users and ProgramData on a 2nd drive. I have found many samples of how to do this (see below). However I would also like to move Program Files to a 3rd drive as well. i.e.: C:\Windows [SSD] D:\Users [HDD1] D:\ProgramData [HDD1] P:\Program Files [HDD2] P:\Program Files (x86) [HDD2] I have found that this was possible using unattend.txt in XP but all documentation or examples I find about Win 7 only mention Users and ProgramData, not Program Files. Is this possible using an answer file? Sample unattend.xml for Users and ProgramData: <?xml version="1.0" encoding="utf-8"?> <unattend xmlns="urn:schemas-microsoft-com:unattend"> <settings pass="oobeSystem"> <component name="Microsoft-Windows-Shell-Setup" publicKeyToken="31bf3856ad364e35" language="neutral" versionScope="nonSxS" processorArchitecture="amd64"> <FolderLocations> <ProfilesDirectory>D:\Users</ProfilesDirectory> <ProgramData>D:\ProgramData</ProgramData> </FolderLocations> </component> </settings> </unattend>

  • How to clone a HDD and then use the clone with VMware (so that Windows works!)?

    - by Ahmad
    I have a system on which Windows 7 is installed, and I am trying to make a clone of its HDD image, which I then want to use in my main PC with VMware, so that I can boot Windows 7 off the cloned HDD. I used Ultimate Boot CD v5.1.1 with the system whose HDD I wanted to clone, and I cloned it using EaseUs Disk Copy, which comes with Ultimate Boot CD. The source HDD was 250 GB in size which had 3 partitions, while the USB HDD I attached to the system, which was supposed to be the destination/clone HDD, was 320 GB in size. I chose to create an exact replica, and so 250 GB worth of data (partitions, etc.) was copied exactly, and the rest of the space was un-allocated. I now connected this USB HDD to my main PC, fired up VMware Workstation 8 and defined a new Virtual Machine, and chose to boot off the USB HDD. Result is that when Windows is booting (from the cloned HDD inside VMware), I get the blue screen error before I reach the login screen. How can I change my methodology so that Windows even boots from the clone? I can change any tools I use, etc.

  • IDE Motherboard to Boot from a SATA 1T Hdd

    - by JavaMan
    I want to use my SATA HDD in my very old ASUS A7V8X-X motherboard (made in 2003). I intended to buy a cheap adapter for this. Say something similar to this one: http://www.cooldrives.com/satoidecofor.html But would there be any issue if I want to boot from this SATA drive? My impression is that these kind of adapters convert SATA signal and commands to PATA directly and such a low level conversion should be transparent to the motherboard and BIOS - in case the BIOS doesn't support SATA. And, for my motherboard, it sure doesn't. Does anyone ever used such a kind of adapter to support a boot drive? Any success sorry?

  • Dell Inspiron 1525 - internal hard drive not detected

    - by GingerT
    Others have asked about this issue but had intermittent access to their HD, therefore their results did not apply to this situation. I have tried reseating the HD to no effect. I also tried booting from the Internal HD to no effect. Next step get a connector cable and move the data to a different HD, or send in for HD recovery? Any suggestions?

  • Where do vendors publish internal transfer rates of HDDs?

    - by red888
    So I've started to dig into storage fundamentals and found that in order to calculate the IOPS of a HDD you need to know the internal transfer rate of the drive (time it takes data to move from the platters to internal disk's cache). I went on newegg and even a few vendor sites and could not find this info published for any HDDs. Is it sometimes called something else? Take this link to a seagate HDD for instance. Nowhere do I see "internal transfer rate", but I do see something called "Sustained Data Rate OD"- is that the same thing? Just so you know where I'm getting this info (Book: "Information Storage and Management Storing, Managing..."): Consider an example with the following specifications provided for a disk: The average seek time is 5 ms in a random I/O environment; therefore, T = 5 ms. Disk rotation speed of 15,000 revolutions per minute or 250 revolutions per second — from which rotational latency (L) can be determined, which is one-half of the time taken for a full rotation or L = (0.5/250 rps expressed in ms). 40 MB/s internal data transfer rate, from which the internal transfer time (X) is derived based on the block size of the I/O — for example, an I/O with a block size of 32 KB; therefore X = 32 KB/40 MB. Consequently, the time taken by the I/O controller to serve an I/O of block size 32 KB is (TS) = 5 ms + (0.5/250) + 32 KB/40 MB = 7.8 ms. Therefore, the maximum number of I/Os serviced per second or IOPS is (1/TS) = 1/(7.8 × 10^-3) = 128 IOPS.

  • DDRescue on Windows or another options like DDRescue for Windows

    - by Frank Thornton
    I have a drive with failed sectors ect... I can't image it with Acronis as it hangs. I can't with Knoppiz it hangs. CHKDSK hangs. I want to use DDRescure but I don't have any Linux boxes running at the moment. I could do is in a VM but that seems like it would be slow and problematic? Are there any ways I can data recovery this disk from my Windows machine or is there an ideal way to work with DDRescue on Windows?

  • How to use File History with Recovery partition?

    - by Karl
    I formatted the recovery partition right after installing Windows 8. I'm curious as to why File history only allow the use of external HDD. Instead of using the Recovery Partition. I can't find a way to use it. I decided to use it exclusively for Restore Points. Is there any way to make the Recovery Partition exclusively for the use of File History? Or should I use 3rd Party programs instead, (Easeus Todo Backup, Macrium Reflect, etc)?

  • Recover hard disk from Raw format

    - by user1632736
    I have been all over the web today with no results. So my drive was encrypted (truecrypt) the whole drive where windows resided. I decided to partition it to install W8 and forgot it was encrypted. So the drive got damaged and not accessible. When connected to a computer it asks for formatting. Somehow I enabled the drive through TrueCrypt on another computer and I could see and get all the files. Then I decided to decrypt the drive thinking that everything would be back to normal. After decryption my drive is not NTFS it is in RAW format. I am trying every possible way to recover, and I am desperate enough to ask lol. I tried: ddrescue (linux) (not mountable, no signature, ntfsfix no good) testdisk (linux and windows) Sees the partitions but cant do anything Many recovery applications. etc etc. I read in different places that doing a quickformat to NTFS and then doing a data recovery might help. I would definitely like a second opinion. Any suggestion would be really helpful

  • Resizing partition in Windows 7: how long does it take?

    - by PaulJ
    Okay, maybe this is me worrying about nothing, but... I have a 500 Gb. external drive where I want to create a second partition. I plug it into my Windows 7 box, use Disk Manager and pick the "Shrink Volume" option. It says that the maximum amount to shrink is around 150 Gb. I hit "OK" and it starts working... and it's been going on for about half an hour. The light of the external HD is constantly working. Disk Manager is greyed out and has the "does not respond" message on the top bar; basically, it's behaving as a non-responding application. Is this normal for a drive of this size, or did the application hang? How long would it typically take for a drive like this to resize its partition?

  • Completely replacing (upgrading) a RAID 5 array of disks on an ESXi server

    - by jshin47
    I have a development server that runs several VM on ESXi 5. It has an array of disks in the RAID 5 configuration where all of the disks are currently the same size. I would like to expand storage on this box greatly, but I am not sure what the smartest way to go about this would be. My current plan is to: Turn off all VM Copy VM folders from server to another location Verify that I can mount all the VM on the new location (ie that the copy went ok) Replace all the disks with new, bigger ones Reinstall ESXi5 Copy the VM back over This seems like it might take a while to accomplish and is not terribly slick, especially since I will have to reconfigure ESXi 5, but is there a smarter alternative?

  • Using Ubuntu switch a failing windows 7 harddrive?

    - by firefusion
    My laptop harddrive has developed some serious read errors in the windows partition. Windows 7 still boots but every single action takes an aeon, and it is definitely due to a harddisk error not due to any spyware. I'm using the Ubuntu partition now. I've ordered a new harddrive but my laptop didn't come with a Windows 7 install disk (I think I was meant to make one with the windows 7 tools). So how can I install Windows 7 on my new harddrive?

  • Corrupted NTFS Drive showing multiple unallocated partitions

    - by volting
    My external hdd with a single NTFS partition was accidentaly plugged out (kids!)... and is now corrupted. Iv tried running ntfsfix - with no luck - output below.. When I look at the disk under disk management in Windows 7 it shows up as having 5 partitions 2 of which are unallocated - none have drive letters and it is not possible to set any (that option and most others are greyed out) - so I can't run chkdsk /f Iv tried using Minitool partition wizard which was mentioned as a solution to another similar question here. It showed the whole drive as one partition, but as unallocated, and the option -- "Check File System" was greyout. Is there anything else I could try ?

  • Is it a very bad idea to create disk image of mounted disk?

    - by Maciek Sawicki
    I would like to backup my server. For example using dd: dd if=/dev/md0 of=/some_network_share I wonder if this image will be vary inconsistent if /dev/md0 is mounted? Would it be possible to convert such dd image to vdi drive and create working virtual machine? Using this command for example: VBoxManage convertfromraw ImageFile.dd OutputFile.vdi Network traffic is disabled on firewall (there is only connection to/from one remote machine where image is copied).

  • Writing to external drive runs out of space prematurely

    - by steve
    I have a USB 2.0, 500 GB HDD. I am writing a bunch of data to it, that I previously recovered from the drive. I have formatted the drive in exFAT, since the drive will be used with Windows and OSX. At first, I tried using Windows explorer to move the files over to the drive (about 160 GiB worth) but after copying about 30% of the data (according to TeraCopy), Windows Explorer reported the drive as out of space, and that it was completely full. WinDirStat only showed the size of data that had been copied over... Where did this extra space go? Why is there a 300+ GiB discrepancy between the usage reported by the files and what Explorer sees?

  • "Can't find root filesystem / error mounting /dev/root" when booting to new kernel

    - by salparadise
    I am trying to upgrade my kernel from 2.6.18-274 to 2.6.39 for some wireless card drivers. When I boot into the new kernel I get the "Can't find root filesystem / error mounting /dev/root" googling led me to this page http://fedoraproject.org/wiki/Common_kernel_problems#Can.27t_find_root_filesystem_.2F_error_mounting_.2Fdev.2Froot From what I am reading seems to be an issue with a driver for my SATA controller or HD, but I can't find what option I need to add to the kernel. Doing a diff from the old initrd to the new one gives me the following: root-> diff /tmp/kafter /tmp/kbefore 6a7,8 > lib/dm-message.ko > lib/dm-region_hash.ko 8a11 > lib/dm-raid45.ko 13d15 < lib/dm-region-hash.ko 16a19 > lib/dm-mem-cache.ko Do I need any of those? not sure if I would need dm-raid45.ko as I am not running a raid. I have the same SATA and IDE options configured for both kernels so not sure what else to look for, any help is appreciated.

  • Disable RAID Controller

    - by B.Mr.W.
    I have some decent HP Proliants server that come with "HP Smart Array P410i Controller" enabled, I am using these boxes to set up a Hadoop cluster and I know, RAID is for sure a no-no for Hadoop since the application itself will take care of data redundancy and extra intelligence provided by RAID won't be helpful and might turn down the performance. I tried to disable the devices at the BIOS and the box cannot even access the disk afterwards. So I am assuming the controller is sitting between disks and mother board, and we have to turn it on and configure it to "level0" or something like that. I am wondering what should I do to "disable" the RAID functionality so it will fit into the Hadoop environment.

  • Suggestions for Backup solution

    - by jiewmeng
    i am considering between windows home server simple nas extra HDD's in desktop btw, i will be the main user i am looking to fulfil the following needs: reliability (i am think RAID 1 or 5) not so prone to virus/malware infections (will using a separate NAS or home server help? say windows home server is still a windows pc except separated by network?) power efficiency (eg. spin down when not in use) download (eg. i may want to dl big files/torrents overnight and i may not want to use a full powered PC for it? does a full pc vs NAS provide significant power usage to justify cost of new system esp. since i am only user?) performance (i guess i like to write/access my files fast, on 2nd thought, maybe for backup i can forgo this? maybe for a WD Green HDD? but how much slower will it be? plus since i am the only user, i think the whole HDD will be mine?)
