Take a look at scsi-defects.pl. It can extract both the primary and grown defect list from the disk. You find it in the /usr/src/tools/tools/scsi-defects directory. You should be aware of the bug discussed in PR#5846 if you are running 3.0-CURRENT and attempts to use this program. Last week, after having been forced to low level format the system disk on the machine which acts as cvsup.no.freebsd.org, I've started using that program from cron to monitor the growth of the grown defect lists on the attached disks. - Tor Egge To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message
