ok so here is the deal, i was backing up my micro sd card "with 7z" for my cyclo ds, it got to 100% and then just froze there at 100% i killed the process and now the archive will not open, i have the archive stil but my brother accidentally reformatted the sd card thinking it was his, so i have to recover this 3 GB archive, i have some Checksum and hash results from peazip if anyone wants to see it, if anyone could help me i would really appreciate it
