You can rsync the corrupted file back to the other machine, and compare the files there. I use the following command to compare binary files: $ diff -u <(hexdump -C file1) <(hexdump -C file2) If the difference is only in a few bits, then it is likely a memory error. If there are whole blocks of 0x00 or 0xFF then it might be a disk error. -- Rodrigo
