#1 Post by Chili » 12 Feb 2014, 21:40

Hi!

With bad rsync argument, I'm delete some *.dmg file (with cc. 2000 photos) and trying recover these files.
Other dmg files hexdump:

Concerning the first 3 files, you can use the signature

Code: Select all

dmg 0 0x78 0x01 0xed 0xd7 0x41 0x6a 0xc2

I read first before I posted my ask.
I don't understand this way. It's too hard for me.
I got HexEdit for mac. What must I do after ? Open a .dmg in HexEdit. It's not clear for me. I'm sorry :|
I know, I must create the photorec.sig with textedit
