I just had this problem on one of my machines at home last week. It turned out that the disk had 6 bad blocks that the disk's firmware would not reassign, probably because the error was a hard error. As I didn't want to purchase another disk (I have a mortgage to pay off), a read/verify to reassign the bad blocks solved the problem. If I had this problem here at work, I'd have replaced the disk. As and aside, if you want to take a look at your SCSI disk's primary (from the factory) and grown (detected by the disk's firmware or through a read/verification) defect lists issue, camcontrol defects 0:0:0 -f phys -P camcontrol defects 0:0:0 -f phys -G Replace 0:0:0 with the physical address of the disk you want to display defects for.
