    DISKPART clean performed accidently. how to recover data?

    Hello everyone,
    I had major partition problems and tried fixmbr,fixboot,etc and even rebuilding bcd was not working. I was misguided by one of the other Forums and entered:
    DISKPART Select Volume 1
    DISKPART Clean Volume 1
    The Volume has been cleaned
    [If it was to delete all data, I thought it would ask Y or N]
    where volume 1 was my C drive. I had data on other drives. Immediately after this the computer hung and I was forced to restart. All this while the MBR was not working and I was on Windows 7 installation disc. Now it does not detect my Hard Disk or any of the Volumes and shows Hard Disk as 249 out of 249 Gb free. I have no choice but to go to Windows 7 Disc where there are no installations or data.
    Of what I have read, this command only clears the Partition List..
    While I was trying fixmbr, I even used gparted Live disc where it turns out that there is some "recursive" bug which was found.
    Please help me, there is vital information on the disk as it is my office computer.
    I need to recover all the data. Its very urgent. I have committed a huge blunder but is there way ?

    Do not format the drive or do anything other than download and burn to CD free Partition Wizard, burn to CD using Windows Image Burner.

    Boot PW CD by tapping the one-time BIOS boot menu key at boot, choose DVD/CD drive to boot.

    Then follow this video for Partition Wizard Partition Recovery Wizard - Video Help.

    Thank you for your reply! I Tried MiniTool Partition Wizard Home Edition by booting on CD
    It shows the HD as 232.89 Gb Unallocated - "Bad Disk".

    In Gparted I get error like "Libparted Bug Found" and Partition Table error!
    I tried TestDisk/Photorec in Gparted - both did not show the partition table and showed nothing found to recover.

    I tried CMD prompt in Windows Installation disc- it found 0 installations and when i switch form X:\Sources to C:\ is gave an error of bad or corruptable disc I guess!

    "Partition Wizard" flagging a HDD as bad doesn't necessarily means it is faulty. If partition table is screwed, PW may flag the disk as bad ( i have seen PW doing this if the disk type is "Dynamic" ).

    In Gparted I get error like "Libparted Bug Found" and Partition Table error!
    This could be the reason PW flagging the disk as bad.

    I tried TestDisk/Photorec in Gparted - both did not show the partition table and showed nothing found to recover.
    Have you run a "Deep" scan with "TestDisk" ?. Which exact boot disc you used ? ( is it "Gparted" or "Parted Magic" ).

    Some background info will be helpful. What exact problem you had experienced with the system ?. Can we have a link to the other forum's thread in which you are instructed to run DISKPART ?.

    Also i highly recommend to stop trying commands like "Fixmbr" etc to not make the problem worse.

    Normally a bad disk message would warrant a check of your disk with manufacturer's diagnostic utility.

    But here the history you have given - problem with MBR, trying to fix mbr, running diskpart clean to clean the first sector all suggest that there can be other reasons as Anshad Edavana stated.

    Now Diskpart clean also went through and upto that point the drive was accessible.

    At this point I would suggest that you should write the MBR code using TestDisk.

    Since you have already used Test Disk, I shall straight away go to the fourth screen.

    There instead of Analyse move down to [MBR Code] Write TestDisk MBR to first sector ENTER and then y and again y on the next two screens.

    If MBR code is successfully written,you will get a confirmation screen and you are better off than before. Press ENTER. Shut down your computer after closing the Test Disk etc.,

    Boot now with Partition Wizard. Do you still get a Bad Disk message? If you no longer get a bad disk message,do a quick scan with Partition Recovery Wizard and check whether partitions are found.

    You can also do a quick search with TestDisk, but if I remember correctly if no bootable partition is found it will not initiate a search.. If MBR Code is written there is a greater chance of it initiating the search.

    caution: psyched long History

    Thanks anshad & jumanji for the prompt reply!

    Long story short: (Flashback History)
    I initially experienced BSOD error about 2 weeks back, it would either get stuck at start screen or cursor with black screen, I somehow rebuilt bcd and after hours of trying it brought back life into my PC. I should have backed everything here! But thought everything is fine, I expanded the space on my C: Drive (thinking its a problem with RAM and lack of space on my system drive) SO i had one primary drive -C and D,E,F as extended drives. No changes in hardware and i made sure system restore is also there.

    What happened now: It would just get stuck at loading windows screen for hours without loading it, I tried Gparted TestDisk even at that time and couldnt recover the table. I had the same bug found error/volume corrupted,etc. After failing, I ran windows installation Disc, it showed my windows installation on C. System recovery detected the problem but couldnt fix it even after several restarts. I had all the files intact untill I ran DISKPART CLEAN - in the help section it showed me that 1mb of beginning and end would be deleted. I ran it and immediately found that I couldnt switch to C: Drive. the computer hung there and I was forced to restart! Now it would show as "Please insert boot media and press any key". I'm guessing it couldnt even detect my harddrive any more after the command.

    I did see the "Write MBR" command, It would not overwrite any files right? I am running out of options now! Do I remove my harddisk and put it back and then retry? The bad volume/ unallocated space scares me at present

    No, the MBR will be written to Sector zero where it should be. I shall post a screen in a shortwhile.

    The description you provided indicates possibly failing hard drive. I would recommend diagnosing the hard drive and verifying it's health before any other steps. It will be safe to check the SMART data of HDD as a first step. Please follow the below steps.

    1. Download "Parted Magic" from Download Parted Magic - MajorGeeks

    2. Boot from it and open "Disk Health" (GsmartControl ). Select your HDD and double click on it.

    3. Navigate to the "Attributes" tab and choose "Save As" and save the file with the name SMART.

    Upload this report with next reply. If you have a wired broadband connection, you can connect to the Internet from within "Parted Magic". There is "Firefox" to browse net.
