Thank you John. The thing is my data was not overwritten, corrupted, etc. Some was, but I know which parts. Basically, I just cleared the file system designation. So if a file is 64K, does the first 32K on drive 1 contain the first half of the file and the first 32K on drive 2 contain the second half, or are the 32 size chunks on random locations?
