I'm on OSX 10.3.9, PS7. Copied a ton of files from my HD to an External LaCie, only to find that most (all?) of my psd and flattened tiffs are now corrupt. Error: This document has been damaged by a disk error. The most likely causes of this error are: a defective disk drive, a defective disk drive cable, or incorrect peripheral cable termination. Some of the pixels in this document may be invalid. Open anyway?....click okay and the files are a MESS or some won't open at all. Ran DiskWarrior - fixed a ton of frag, but didn't fix the PSDs. Please please tell me there is software that can fix these files?
