how to retrieve info from a bad disk?
hi,
I have a disk ( I tera Bytes it contains important data!!!) formatted with nfts, somebody used it in wind$ a virus seems destroy "something" in partition table ???!! Now no access is possible, although the partition is recognized as /dev/sdb1 with correct sie, but no possibility to retive files. I tried ntfs-3g /dev/sdb1 t gave segmentaion fault I tried testdisk it analysed the disk and gathered the data, I tried to list the files , it gave same error as ntfs-3g, I mean segmentation fault?? Is there another rescue software ?? thanks for help regards |
Have you tried testdisk's partner, photorec?

Hi,
Yes I tried it !! I used ntfs-3g too here is the test: I check ntfs-3g ( tool on linux to manage ntfs file system) to fix the error. ntfsfix /dev/sdc1 gives the output: mft corrupted ... is there a chance to recover something ??? " Mounting volume... MFT is corrupt, cannot read its unmapped extent record 280867 Note : chkdsk cannot fix this, try ntfsfix Inode is corrupt (0): Input/output error Failed to load runlist for $MFT/$DATA. highest_vcn = 0x3, last_vcn - 1 = 0x1a53f Failed to load $MFT: Input/output error FAILED Attempting to correct errors...

I think you may be best off to quit while you are ahead and get professional help if the data is important.
Testdisk was probably your best chance. Every time you do anything with that drive it makes it harder to recover the data. When you do get it straightened out, one way or the other, think seriously about partitioning the thing into something like 400 or 500gig partitions. One huge partitions is kind of putting all your eggs in one basket. |
Safecopy is a data recovery tool which tries to extract as much data as
possible from a seekable, but problematic (i.e. damaged sectors) source - like floppy drives, harddisk partitions, CDs, ..., where other tools like dd would fail due to I/O errors. Homepage: http://safecopy.sourceforge.net gddrescue Quote:

Learn something new all the time around here.
Both packages in the Debian repos too. |

Hi,
I had a similar problem. Finally resolved it by: 1. Restarting server using 'Live Debian' Squeeze. 2. Install lvm: aptitude install lvm. 3. After install, partitions appeared in file manager, selected required partition. 4. Inserted USB Stick. 5. Copied required files to USB stick. DONE! Regards Nick |
