Hi Guys,
I seem to have a problem with an NTFS (windows XP) disk with a volume that
has gone corrupt.
I have used ddrescue to read the entire /dev/sda1 partition into an file
and I have tried to mount and repair it from linux using ntfs and ntfs-3g.
This is my console with my attempts on the file image:
mount -o loop /root/dw/eastside_wip /root/dw/disks/eastside/
mount: wrong fs type, bad option, bad superblock on /dev/loop0,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
mount -o loop -t ntfs-3g /root/dw/eastside_wip /root/dw/disks/eastside/
Failed to open ntfs attribute: No such file or directory
Failed to load $MFT: No such file or directory
Failed to mount '/dev/loop0': No such file or directory
ntfsfix eastside_wip

Volume is corrupt. You should run chkdsk.
What, do you think, would be the obvious next step?
All suggestions are welcome. And thanx in advance
Have you tried tesdisk?

If the NTFS boot sector is damaged, data can not be accessed.
Windows will prompt The drive is not formatted, do you want to format
it now? Linux mount will display wrong fs type, bad option, bad
superblock
TestDisk let you manipulate and fix the boot sector of NTFS partitions. Select
the partition you want to modify and choose Boot.
Recovering NTFS Boot Sector on NTFS Partitions using its backup
TestDisk can use backup boot sector to fix corrupted NTFS boot
sector. The primary boot sector is sector zero of the filesystem, the
backup NTFS boot sector is located near the end of the filesystem.
TestDisk checks the boot sector and the backup boot sector. If the boot
sector and backup boot sector mismatches, you can overwrite the NTFS
boot sector with the backup boot sector (Backup BS) or vice versa (Org.
BS). Dump can used to display the boot sector content in both
hexadecimal and ascii.
Rebuilding NTFS Boot Sector on NTFS Partitions
If both NTFS boot sector are corrupted, you need to rebuild NTFS
boot sector, TestDisk searches the MFT (Master File Table: $MFT) and
its backup ($MFTMirr). It reads the mft record size and it computes the
cluster size, It reads the Size of Index Allocation Entry in the root
directory index. Using all these values, TestDisk can provide a new
boot sector. Finaly it lets the user list the files before writing.
Repair NTFS MFT
The MFT (Master File Table) is sometimes corrupted. If Microsoft
Check Disk (chkdsk) failed to repair the MFT, run TestDisk and in the
Advanced menu, select your NTFS partition and choose Repair MFT.
TestDisk will try to repair the MFT using MFT mirror, its backup.
