my drives are C D E....F is my Cdrom, C,E are now on my primary drive(1) and D is my 2nd drive. I never figured out why my second drive didn't become E?
when I added the 2nd drive the programs I had on my 2nd partition(D) of drive 1 became lost(shortcuts couldn't find etc.) because after adding the 2nd
drive the computer starting reading it as E??? And drive 2 became D???
How can I avoid these problems this time?


Jeff, I will have to defer to one of the more learned ones here.
Afraid I only know enough to get you in trouble.

My understanding, sorta', is if you have one HDD. It has two partitions, C & D.
Now you add the second drive then things change, C stays on 1st drive, D goes to 2nd drive, E stays on 1st drive, F would be on 2nd drive. Alternating so to speak. I'm sure there is a way for the originals to stay with 1st drive and have the 2nd drive separately but I don't know the mechanics. If you have a line in
Config.sys, Last drive=Z, then the CD Rom drive should follow the last drive on HDD. Maybe go to a DOS prompt, or Explorer, and Type in C,D,E,F,G.H and see if anything is recognized.

Sorry I can't be of more assistance,

Jeff,

Windows has rules for assigning letters to drives and I don't know them all. But, for instance, primary partitions get first crack followed by the logical partitions. I'm not sure if there is any way you can alter this with DOS, I'm pretty sure it can't be done with Windows.

PowerQuest has a utility called DriveMapper that I think comes free with PartitionMagic but I've never used it. Just another learning curve I didn't start up.

Another method I think is using something like PartitionMagic you can make all partitions on your extra physical disks be logical partitions, so that the letter ordering is "logical".

When my shortcuts get screwed up I either don't use them or I re-create them.

Drive lettering

I will add a little to the previous posts.

As indicated the OS assigns C to the primary partition on the first physical drive and then D to the primary on the second physical drive. Then starts filling in E, F, G on the logicals on the first drive and then moves to the logicals on the second physical drive.

If the second physical drive is formatted with no primary partition ie only logical drives then the drive lettering on the second physical drive will start after the letters on the first drive have been assigned.

For example with two harddrives..the first with a primary and two logical partitions and the second with only two logical partitions the drive letters would be C,D,E on the first and F,G on the second harddrive.

One can map harddrive letters in NT..ie change the standard drive sequence..my guess is you can not mess with the C designation.

Win 95 goes not allow for harddrive drive mapping.(CDROM can be mapped)

My preferred method is to have a large C drive with OS and program executables. I use additional harddrives for file and data storage thus avoiding relettering issues....although relettering issues can be addressed and there are good arguements for a small C partition.
