Change Disk Numbers

I have recently moved my new 6 Gb/s operating system drive from a 3 Gb/s SATA controller to a 6 Gb/s SATA controller. The only problem is that the disk number changes.

For example, instead of my operating system drive being Disk 0, it is now Disk 2, and instead of being at the top of the list in Disk Management and Macrium Reflect, it is at the bottom.

Can the disk number be changed, or doesn't it matter?

Hi,

It doesn't matter.

The Disk # that Windows assigns a drive is based on the Motherboard port the drive is plugged into. Is your 6GB SATA port a card or is it directly on the motherboard? If a card, Windows will always assign the Disk 0 to SATA port 0 , if there isn't one then SATA port 1 on the motherboard. If you added a SATA III card for 6 GB as I have, then it will assign a lower Disk #
But it doesn't matter, though when the computer boots it goes thru all the ports till it finds a bootable drive, which takes place in a split second, so being Disk 0 will make it a split second faster to boot.

It's just on the motherboard. Maybe I should have used a card.
It's an old GIGABYTE GA-X58A-UD7. It's getting old, but it's still going well.

I was originally using the Intel ICH10R 3 Gb/s SATA controllers, but switched to the Marvell 6 Gb/s SATA controllers, but I had to switch to Standard SATA AHCI Controller drivers. I have one SSD and two hard drives. The SSD and one hard drive is plugged into the two Marvel controllers, and the second hard drive is plugged into a GIGABYTE SATA controller.

The drive plugged into the GIGABYTE SATA controller is a bit odd at boot up.
For some reason, it displays a blue message:

HDD0: Press any key to continue

But in the BIOS, it says SCSI-0

Didi you set your BOOT SSD to be default in the BIOS ?

Yes.
I think it is the GIGABYTE SATA controller that causes the problem. Because if I move it to a slower South Bridge ICH10R Intel controller, it doesn't happen. I have my primary SSD and secondary hard drive on the only two 6 Gb/s Marvell controllers, so I have to choose a controller for the third drive. It is not a big problem really. It doesn't require any user input. It just pauses for a second.

It could be something to do with the fact that the GIGABYTE SATA controller offers three modes. IDE, AHCI, RAID/IDE. I have it set to AHCI. Another problem with the third 6 Gb/s drive is that it is only running at 1.5 Gb/s instead of 3 Gb/s as the controller supports.





Just part of the fun of keeping older computers running.

I am using an old red SATA data cable. SATA cables don't differ in speed, do they?

No they don't but may differ in quality, length and type of connectors, some have metal covered ends with a retaining clips, have gold plated contacts, are stiffer or softer etc.
