I see. :-/ Have you tried whether the error also occurs under Windows? What does the kernel output the moment the write fails? For hard discs, "dmesg" or /var/log/syslog contain kernel messages in this case, which include exact sector numbers. If you see this kind of message in your log, the Rev drive is telling Linux that it can no longer read or write the respective sector, which would be a strong indication that the disc is broken. > In fact this is a 35 Gigabytes removable hard drive, the one described > on the page hereafter: > http://en.wikipedia.org/wiki/Iomega_REV I cannot find any information on whether the drive uses magneto-optical technology (unlike "normal" hard drives, which are "magnetic-only" - I suspect that it _is_ magneto-optical, and this also sounds like it: > 2) REV drives employ a two dimensional error correction system that > requires the host to send data in 64KB aligned chunks to achieve optimal > performance.

BTW, if you want to find out whether bad sectors still exist on the disc, you can use the "badblocks" program (e2fsprogs package). > Might be that the IO error could be related to failures which occurs when > trying to write a file greater than 1 gigabyte? As far as I know, UDF has no such size restrictions. All the best, Richard -- __ _ |_) /| Richard Atterer | \/¯| http://geht.net.gibts.bei.atterer.net ¯ '` ¯
