Recover Partition endmark 0xAA55, fail to recover

#1 Post by pirateskiller » 23 Apr 2014, 14:17

Hi there,

I wondering any way to recover this pendrive.. I'd tried photorec but some files were recovered some were not.. is there any way to recover its partitions?

Errors I got were:-
1) endmark 0xAA55
2) the harddisk seems to small


here I attach the teskdisk.log

Run TestDisk, use the Geometry menu to set 500 cylinders, Analyse, Quick Search, Deeper Search, try to list the files of your partition. If it works,
- set this partition as *(bootable) or P(rimary)
- on next screen, choose Write, confirm.
- if asked, choose BackupBS and confirm
- Quit
