D: Drive is drive 0; C: drive is drive 1 How to change
I have a Optiplex 3010 and am trying to add a second drive.
No matter what I do I cannot get my c: drive to display as drive 0
I have change cables, position of the drive in the frame and it still displays the c: drive as drive one.
This would not be a big deal but my backup program looks at drive 0 as the source and drive 1 as the destination. So, I am unable to backup my computer.
Any suggestions?

- Shut down your PC then disable/unplug (both the power and sata cables) your D: drive.
- Now reboot and see if your C: Drive shows as Drive 0.
- If it does, shut down and reconnect your D: drive, then start back up and see if C drive remains as drive 0 and D drive shows as Drive 1.
Post your results.

If the above suggestion I made doesn't work...
I read a thread on the MS forum today where an MS rep stated that the reason why a drive other than the C Drive is getting listed as Drive 0 is because when your PC is booting up, the other drive is spinning up faster than the C drive. Therefore, it is getting enumerated first and therefore it gets assigned as Drive 0. So...
What you need to do is look at your C Drive to see if it has jumper pins and see if it is jumpered to to be in PUIS mode (Power Up in Standby). If it is, remove the jumper. And as an added measure (especially if the C drive has no jumpers) if the D drive has jumper pins and can be jumpered for PUIS, then jumper that drive for PUIS. This may very well fix your problem as it will ensure (hopefully) that your C drive will spin up before your D drive will, hence enumerating your C drive as Drive 0. Unfortunately not all drives will have jumpers.
If one or both of your drives support PUIS mode, and have jumper pins, the label on the hard drive will tell you on which pins the jumpers need to be set to enable PUIS.
If neither of your drives have jumpers and your BIOS has a PUIS function/option, then lookup your D drive model on and see if it supports PUIS (even if it doesn't have jumpers). Then set your BIOS PUIS function to be enabled on your D Drive and this should solve your problem.
