RE: Corrupted file on a copy

["David Sanchez" <david.sanchez@lexbox.fr>]

Unfortunately, the cmp command shows me a difference between the 2 files!
I known that it is a strange behaviour and that probably come from my code but I don't find it yet :(
More, I try the last linux kernel 2.6.13 from linux-mips.org with the last busybox version and the problem persists!

Use `cmp` to compare the two files. You could have discovered
a bug in your checksum utility, you need to isolate it to
the file-system. FYI, I have never seen a copy of a file, including
the image of an entire DVD (saved to clone another), that was not
properly identical.
