New machine build yields drive letters problem in Computer Management

Thread needs solution

Hello,

Just finished updated my machine with a new SSD and a 500GB HDD for storage. Win 7 was installed on the SSD with AHCI enabled.

The problem is, if it IS a problem, that in Computer Management in Win 7 the drive letters of the SSD and the HDD are reversed. That is to say the SSD is Drive "1" while the HDD is Drive "0" .

Will this discrepancy effect my Acronis backups when I make them?

I have tried to change the order of the SATA cables but that makes no difference to Windows. If I fool with it too long, then the BIOS doesn't even know the HDD is there or vice versa. I can have one of the two but not both! Now luckily I have it to the point where I started.... Drive "0" is my HDD and Drive "1" is my SSD.

Somewhere this information must be stored in the registry but I haven't a clue where to look.

As long as the odd numbering doesn't hurt my backups maybe I should just forget it's there! ?

Thanks to all in advance.

Drive 0, 1, 2, 3, etc. are not drive letters, they indicate which SATA port on the Mobo that a drive is attached to. It does not matter in most cases which port the boot drive is attached just as long as the boot priority is set correctly in the machine bios. In fact, insuring that your SSD is listed first in the boot priority screen in your bios just might straighten out your port designation issue. Most SSD's are recommended to be attached to SATA port 0 by the manufacturer however, there are some that recommend SATA port 1 be used. You can usually find that information in the documentation for the drive or on the manufacturer website. In any case none of this should effect Windows or the operation of your machine.

If machine is a desktop, switch the connector on the motherboard from 1 to 0,
and the storage disk to connector 1 just vacated by the SSD.

if machine is a laptop, you will need to switch the disk positions inside the computer.
