Today I've been getting a bunch of console messages like these: sd0(ahc0:3:0): HARDWARE FAILURE info:24e851 asc:15,1 Mechanical positioning error , retries:4 sd0(ahc0:3:0): MEDIUM ERROR info:24e851 asc:11,0 Unrecovered read error , retries:3 There are many more MEDIUM ERROR messages than HARDWARE FAILURE messages. However, I haven't experienced any loss of data yet or noticed anything else bad. I'm running FreeBSD 2.2-960612-SNAP and I've got a Quantum Fireball 1280 with an Adaptec 2940 SCSI controller. I checked the mailing-list archives and found some discussion about these types of errors on -hackers from a year ago, but I'm still not sure what to do. It was suggested to use scsi(8) to "enable the automatic remapping of bad sectors" with something like "scsi -f /dev/rsd0a.ctl -m 1 -e -P 3". Is this still applicable? Is the drive going bad? Anything one can do to fix it? Thanks very much for any help, Pius
