I've seen something like that. During copy, Windows (2000) would sometimes complained that it couldn't write a file, and that file turned out to be corrupted afterwards.

Thanks to a USB hub with "traffic indicators", I was able to figure out what caused the problem: my USB printer! Apparantly some of the traffic on the HUB got re-directed to the printer (I saw that on the HUB), causing the file corruption. By always unplugging the printer when copying files to the Archos, the problem went away.
