Windows 7: Drive letters keep changing

Drive letters keep changing

Hi,

I have just replaced XP with Windows 7. I unplugged the old system disk and put in a new one in the same place, and then removed all its partitions with the Win7 installer and set up from scratch. The system disk is always a primary master on the motherboard ATA controller.

I have two USB hard drives permanently attached - a 320GB WD MyBook and a 500GB drive in an Integra case. I also have a 1.5TB internal RAID1 array using motherboard NVIDIA raid (SATA). Finally, a DVDRW occupies a third SATA port.

Under XP, I used disk management to assign letters as follows:
C: - ATA system drive
D: - 500GB external
E: - 320GB external
F: - DVDRW
G: - 1.5TB internal array

Upon installation of Win7, which went rather well, I used disk management to assign these drive letters. However, most of the time when I reboot, they change such that internal drives are assigned lower letters. This breaks my shortcuts and path references. I have re-assigned the drive letters in the intended configuration a few times now, but Win7 is adamant that these assignments only last until the next reboot. Win7's up to date now, but the problem is still there.

How can I make these drive letter assignments permanent, so that they persist through reboots?

Hello Leondz, and welcome to Seven Forums.

You might see if changing the drive letters using OPTION TWO in the tutorial below may be able to have them stick for you.

Hope this helps,

Wonderful. Second method didn't work straight away - but after a restart they moved around, and ten reboots later they're stuck like anything. Thanks!

I have installed Win 7 on a SSD on C:. My two HDD were assigned different drive letters other than what I would like. Is it safe to change the HDD drive letters in Drive Management without messing up my data? Thanks,

Changing Drive Letters
Is it normal when installing Windows 7 that it installs itself on 'C' Drive and moves XP from 'C' Drive to 'D' Drive even though it appeared to be installing on 'D' during installation?
