I have two SCSI hard drives in the workstation. One is the booting drive working as C:/. The other is mapped as D:/.
I am trying to add a third SCSI hd. In this HP Workstation xw 8200 there is room for 4 SCSI hard drives. Problem is that when I add
the third one, the computer tries to boot from this one with the obvious response that there is no operating system, instead of booting from the one it's been booting from (the C:/ one) all the time. I guess I have to jumper them in some way but I don't know where to place the jumper. The jumpers are showing two facing rows of 6 pins. 12 pins in all. At the moment, none
of the 3 hard drives has a jumper placed. The hard drive I am trying to place as third one (Should be as as slave or Secondary slave I guess is a Worldisk brand of 68 pin.
Anyone's help will be greatly appreciated.

SCSI drives do not use the concept of Master / Slave, but they are addresssed by the ID configured in that jumpers you speak of.

Look at the drivesĀ“ sticker, or search for their manual in the net, and jumper them do different numbers. From memory, you must set the one you want to be the boot drive ( the one you call C: ) as ID # 0.

Worldisk is not a HDD manufacturer. Could we see the label and PCB?

I suspect that HP's backplane selects the drive ID rather than the drive's own jumpers. More information on the original drives would help.

check on boot
Your SCSI controller show info about initialized drives. Check initialization info about initialized devices(HDD's and CD's, optionally any other scsi connected device).
You can also make photo of it and post it here
Otherwise check jumpers on drive

What happens if you switch the positions of the two original HDDs? Do the drives retain their identities or do they follow the backplane?
