My PC is dual booted with [Windows 7 Ultimate/Ubuntu]. While in Ubuntu a text file went missing but the Partition was still there, I booted into Windows & could not find the file although the Partition was there. Then Windows "Blue Screened", after re-boot Chkdsk TRIED to run & gave this message:

"corrupt master file table, chkdsk aborted"

When I click on the Partition drive letter:

"E:\ is not acessible.
The file or directory is corrupt and unreadable".

BlueScreenView identified the cause of the crash as "Ntfs.sys" & "ntoskernel.exe", I booted back into Ubuntu & the Partition was gone. When I got back into Windows BlueScreenView had no data & Windows Minidump folder was empty, how can I recover the Partition? I'd run a bootable hard disk utility against the hard drive to verify that the MFT is not physically damaged/unrecoverable/unrepairable. If your drive is seagate there is SEATOOLS, otherwise other drive manufacturers also have their utilities that you can download and burn to a CD and boot from. You might find that the hard drive itself has FAILED and so rebuilding might not be POSSIBLE on that drive.

What Hard Drive Make/Model do you have?Where is Ubuntu installed to ? ?
Where is 7 installed to ? ?Thanks for replies, there is only one drive on the PC:

Western Digital SATA (WD15EADS-22P)

I can boot into UBUNTU or Windows, there are 3 other partitions which are accessible: UBUNTU,Windows 7,FAT 32. GParted (UBUNTU partition MANAGER) can see the damaged partition & reports it as 500GB but shows no information for used/unused space. I think the data is still there but the Master File Table cannot point to it. Quote from: patio on December 01, 2012, 08:13:52 AM
