USB Hard Disk Partition Recovery

#1 Post by gordian » 15 Oct 2015, 23:51

Hi all,
I hope somebody here can help me with a partition problem on a 320GB usb external hard disk.
Originally the drive had two partitions, both with NTFS filesystem. The first partition was the largest and held all the data, the second was only 16 GB and was empty.
By mistake the disk was used to create a windows recovery media: a 32 GB FAT32 partition was created at the beginning of the disk leaving the rest unreadable.

TestDisk in quick scan and in deeper scan detects the 16 GB partition but not the first one (the one I need to recover...). It also detects a 104 GB partition from the backup boot which (I think) is a leftover of an old configuration.
Here is the log:

Hint for advanced users. dmsetup may be used if you prefer to avoid to rewrite the partition table for the moment:

Check the harddisk size: HD jumpers settings, BIOS detection...
The harddisk (320 GB / 298 GiB) seems too small! (< 425 GB / 395 GiB)

TestDisk exited normally.
I made an image of the entire disk with dd and, on this image, tried to modify the partition table and rebuild the BS. I did not succeed, probably because of an incorrect setting on my side.

I was able to recover something with qphotorec, but most of the important data was not recovered so I would like to try to fix the partition table if possible.
Any ideas on how I could try to fix the drive? :cry:
