And for many other disks, it doesn't gain anything. Except for laptops, i generally don't buy ATA disks. For a good SCSI disk, disckcheck won't report anything. It has the only side effect of remapping a bad block, perhaps a bit earlier than it would have been remapped during normal operation. (If the disk really goes bad, it's very likely that diskcheckd will be too late to detect it anyway.) So for me, diskcheckd could only be useful if it would also read out the SCSI defect lists, and compare them on a daily basis so i get an early warning about remap activity. I'll add the knob to turn it off in sysinstall, which phk forgot to add when he added it to rc.conf. -- cheers, J"org .-.-. --... ...-- -.. .
