how to determine powered up hours on a scsi HDD

I run a software raid 1+0 with 5 Seagate 15k 146 drives (4 primary array and 1 spare). After 12 years I am now on my third replacement drive. I just purchased a new one and the raid is up and running again. I am still running WinXP. The raid card is an old (12 years) Adaptec 39320-a.

Looking around the net for the last few days it appears there are resellers passing off refurbished drives or pulled drives as new. My  question is how can I determine  the number of powered on hours on a SCSI hard disk drive without spending a ton of $$? It seems there are plenty of free utilities to do this via S.M.A.R.T. for IDE (ATA)/SATA drives, but not for SCSI HDD.

Thanks.

SCSI HDDs do not support SMART. But they have log pages which are keeping diagnostic information too.
Look at following man page of sg_logs to find out more on how to access them.

Here is some more information on what kind of log page exist.

Be aware not all drives support all pages and some drives use them in a non standard manner.
You should also consult the reference manual to your specific disk to find it out correctly.

Have you already tried Seagate's own diagnostics via Seatools and directly plugging the drive to a SCSI interface rather than the RAID?
Although the Cheetahs aren't supported by SCSIMax I still thought you could get basic diagnostics including uptime even though they are not SMART enabled - apologies if this has either changed or I've not remembered this right!
