Ok, I've bin rearranging my backup server (ironic as it seems) by copying the entire contents from an NTFS drive, over the network to another machine, wiping the NTFS drive and reformatting as ext3 so i dont have a horriffic data read overhead.
During this transition, some pictures have become corrupted whereby it looks as if only one section of the data is corrupted but has been thrown out so the rest of that line and all of the image following it is "offset"

Has anyone encountered this before? am i screwed? I've searched around for a solution but other solutions eg JpegRecovery dont work, that and of course i dont wanna pay for it.
