I loaned a friend an old XP PC that has a master and slave drive. He
lives some distance from here. I'm pretty sure my drives are WD. He's
trying to replace my slave with a Seagate U6 Model ST360020A used as a
master on an old XP PC of his, but is running into problems. The Seagate
drive doesn't use jumpers as a slave. It just won't boot. It does boot
with the two WDs. Comments?
If you're going to use jumpers, both drives have to be jumpered
correctly.
If the ST360020A will be the Slave, remove all jumpers. (You already
know this, since you mentioned it above.) Also, be sure it's connected
to the Slave connector on the IDE cable. Speaking of the IDE cable, I
would use an 80-conductor cable rather than the older 40-conductor
type, although that shouldn't be a total barrier to operation.
Regarding the Master, then, be sure it's jumpered in a way that allows
the Slave to be present, and be sure the Master is connected to the
proper connector on the IDE cable. No hints on proper jumpering
because you didn't provide the model number.
Before trying to boot with the new configuration, and especially since
there's apparently a problem, be sure to enter the BIOS configuration
screen and make sure both drives are properly recognized, (make,
model, size, and master/slave status), before proceeding.
If all of that is good and the system won't boot, provide details on
exactly what happens. Boot progress, error messages, etc. There's a
slim possibility that the system's boot files are on the drive that
was removed, but you can see if that's the case by looking at Disk
Management. Not sure if you've already checked that.
