USB Disk Unreadble

#1 Post by obstruktn » 23 Jun 2015, 02:49

Hi All :)

I hope everyone is well!
I was hoping that someone could help me recover some files from a USB. The file system was default (FAT32).
USB Details: Chipsbank CBM 2090
Size: 2GB

I have followed the steps provided in the following previous post (http://forum.cgsecurity.org/phpBB3/usb- ... 62-10.html) however I have reached a road block.

I am being presented with the following information:
Disk /dev/sdb - 8388 KB / 8192 Kib - CHS 1024 1 16
Disk = P, Partition = FAT32, Start = 0 0 1 1023, End = 0 16, Size in Sectors = 16384
No FAT found
Search subdirectory 2048/16384 0
and I am presented with the stop option.

Any help is greatly appreciated. Thanks in advance!

Update:

I finished scanning and was presented with what appears to be a primary and secondary boot record both listed as bad. When I selected Rebuild I am presented with "Can't Find Cluster Size" I created a dump file but I accidentally pressed cntrl+c and it exited the terminal :( lol

The recognized size of your flash drive is circa 8 MB instead of 2 GB.
Can you check the size of your flash drive in your disk manegement console to compare it?
