Try turning on your automatic bad sector >relocation with ``scsi -f /dev/rsd0.ctl -e -m 1'' (it's the topmost >couple of lines). Hello, I was seeing this same error so I tried your suggestion. Unfortunately it didn't appear to work. I tried setting the top couple of lines to '1' but that didn't help, so I went back and changed some of the other settings. My fsck's changed so that it told me it was writting zeros over the bad sector. I can reboot, re-run fsck, etc. as many times as I want, and the same bad blocks keep re-appearing. Here is the output of the scsi command ''scsi -f /dev/sd0 -e -m 1 -P 3'' AWRE (Auto Write Reallocation Enbld): 1 ARRE (Auto Read Reallocation Enbld): 1 TB (Transfer Block): 1 EER (Enable Early Recovery): 1 PER (Post Error): 1 DTE (Disable Transfer on Error): 0 DCR (Disable Correction): 0 Read Retry Count: 33 Write Retry Count: 3 Any ideas? This is on a newly installed news server and the problem is starting to get annoying. ;-). Any help would be much appreciated. Thanks,
