Changing the drive letter for 2nd HDD af

By fancmn ·
Hello and thanks in advance for your consideration,

The baseline drive structure on my Win98 SE2 rig was a single HDD (C: & partitions) and CD (E:).

I recent added a second HDD to my rig and discovered the CD had been bumped to the F: position.

As you might expect, this broke most of my existing CD-based software installs.

I had attempted to avoid this problem by hard coding the CD to the E: drive letter (first - last) from Device Manager prior to the install.

I also configured the new drive from FDISK as an Extended partition to reduce the chance of letter shuffles.

Since the CD is not working with most programs anyway, I have moved it back in the alphabet for the moment

The real question now, is how to get the newdrive off the E: drive letter.

Device Manger shows some settings for the new drive under the + Disk Drives heading. But the drive letter assignment cannot be edited from here.

The Registry location for this drive seems to be located under \Hkey_local_machine\Enum\ESDI\Generic_IDE_Disk_Type80 (in my case).

One would think that the current drive letter could be changed from this screen, but it only seems to temporarily change the readout in Device Manger without any other system impact.
A reboot after the Registry change also produces no change.

Essentially, I'm trying to move the new drive from E: to the now clear F: letter.

Once this drive is moved off E:, getting my CD back in line should be simple enough.

Any help would be appreciated...

I did come across this link before posting, but the suggested fix did not work for me.

The /Hkey_local_machine/Enum/ key appeared to be useful, but in practice making a drive letter change there did not produce any results.

Despite making changes to this Key, the new drive never moved.

If you are willing, you can edit the registry settings for the programs so that they will use the new letter for the CD drive.

Just open regedit, and search for E:
Examine the data in the key, and edit as needed for the new letter for the CD drive.

As always, it is a good idea to back up the registry before proceeding with any registry edit.
CAUTION: IMPROPER EDITING CAN RENDER YOUR PC NON-FUNCTIONAL!!
That said, if you are cautious, this is a relatively benign registry edit.

To avoid this problem, I always set my CD drive to a high letter when I setup the system. I normally use "R" for removeable, and "W" for my re-writeable drive.

In theory, one could fix all the mapping errors with software Reg tweaks and by combing through other per-program config files.

But with 40-50 programs installed, this isn't really practical.

See the above listed utility for a more elegant solution.

Your point about CD drive letter assignment at system install is well taken.

Next time I build a system, I will take your advice.
