Recover data from external USB

#1 Post by umair »


Desperately need help recovering data lost from a external USB drive that i attached to my FREENAS system and chose to load it as a ZFS volume. I ignored the fact that it will delete the data i had on it. I used Testdisk to recover data from another USB i had and i was successful. The other drive i have is 1 TB and it took almost 15 hours to finish the analysis and resulted in a error stating : "Can't find cluster size". i would really appreciate if somebody could help me recover my data. I am attaching the logfile that testdisk generated. Hopefully some expert out there can put me in the right direction. Any help would be greatly appreciated. Happy new year.

For some reason i cannot attach the log file. Here is the last few lines :

FAT differs, FAT sectors=0-16/67
first_fat 453088, second_fat 453155
FAT : 32, reserved=0, fat_length=0
find_sectors_per_cluster skip_sectors=89425 (skip_offset=45785600)
Can't find cluster size

P FAT32 0 1953525167 1953525168
Boot sector

Backup boot sector

First sectors (Boot code and partition information) are not identical.
Second sectors (cluster information) are not identical.
Third sectors (Second part of boot code) are not identical.

A valid FAT Boot sector must be present in order to access
any data; even if the partition is not bootable.

FAT: cluster=1768445182(0x696854fe), pos=3031508813
FAT: Can't read directory cluster.
