However Medium Error can also be used as "Something is wrong and I don't know what" ;-) I would try to read sectors using dd. dd if=/dev/da1 of=/dev/null bs=512 iseek=79 count=1 ... dd if=/dev/da1 of=/dev/null bs=512 iseek=88 count=1 and some unrelated sectors dd if=/dev/da1 of=/dev/null bs=512 iseek=0 count=1 If only a single sector (or a few) can not be read I would try to write zero to the sectors.This may clear the media error. (The previous data is obviously lost) Example: dd if=/dev/zero of=/dev/da1 bs=512 oseek=79 count=1 Good luck Stephan _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"
