Most drives now (and SCSI even longer) have automatically remapped bad blocks so the fs manager never sees them. Utilities from the manufacturer are usually needed to do this. Search the list for threads (recent) related to this for more discussion. Regards, Lec snip sig stuff -- Bill ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

However it turns out that what I was asking for was not precisely what I was actually looking for. What I wanted to do was to see the contents of the SCSI bad block table not the OS filesystem bad block table (as seen by the Linux dumde2fs -b or the SCO OSR5 badtrk utilities). It turns out that what I actually need was the sginfo command from the sg3_utils package. Thanks again for your comments though.
