Hello All, An fyi if you get/have ST-15150(n,w) drives that are
OEM Compaq , The boot report shows :
Vendor of : Compaq
Model of : ST15150N or ST15150W
Revision : 6215 or 6216 ( Maybe others )
On Compaq OEM'd drives the jumper J4-7 is IN , If you attempt to
use 'scsiformat' from scsiinfo(1.7) this jumper -must- be removed
or the format -will- report failure . And it seems to actually
fail on the drive itself . In that the next 'scsiinfo -a' or
when rebooting will show that the drive has a corrupt format .
I have found that even the ncr53c8xx.c(v3.2c) driver just at the
time that the drive should report back finished or with an error
-with- this jumper in will begin spewing 'scsi timeout' & 'bus
reset' IE: this maybe what gets our 'corrupt format' above .
Only cure for the 'scsi timeout' is -power off- or -reset- .
Hth, JimL
