recovering deleted digital video ( .dv ) files on linux ext3

#1 Post by imool » 13 Oct 2013, 23:24

Hi!

My comrade brought to me his computer wishing i could help recover some digital video ( .dv ) format files. I must admit that i havent used photorec before and so i started to experiment on test virtual Debian v. 7 computer using ext3 filesystem to get me going. I copied several.dv and.jpg files to one filesystem (about 2 GB big) and deleted them with rm and tried to recover them into different filesystem. I started photorec like this

Code: Select all

# photorec /d /root/pr-data/dir
chose appropriate block device and accepted default options i.e.

Code: Select all

 Paranoid : Yes (Brute force disabled)
 Allow partial last cylinder : No
 Keep corrupted files : No
 Expert mode : No
 Low memory: No
and chose from File Opt only dv and jpg and run Search. As a result i have mostly recovered jpg files but no dv file. Though i get thousands of .dv files with size of 120 000 bytes each, e.g.

Code: Select all

# file /root/pr-data/dir.6/f12480 44.dv
/root/pr-data/dir.6/f1248044.dv: DIF (DV) movie file (PAL)
I would be thankful if somebody could get me forward on this, is it i miss something about how to use photorec (i have some library not installed?) or digital video .dv files undelete isnt supported yet? (Actually my comrade's computer is powermac g5 runnig mac os x 10.4 and there i have similar results.)

My test virtual computer has photorec installed from debian v. 7 package management

Code: Select all

# photorec /version

After selecting the disk device, have you selected the partition and choosen Search, ext2/ext3, Free ?
