just curious why you have a logical drive set up as "A"....... I would expect that to cause a few issues with older software which expect A & B to be floppy drives.......
Myself, I've always wanted to use those drive assignments for hard drives since I've always hated floppies.
I've used A & B for hard drives assignments since I started running a 64 bit version of Windows.
The last software I used that looked for those drive letters to be floppies was 16 bit, which will not run in 64 bit Windows.
Funny, I just checked and I loaded my first version of 64 bit Windows exactly 4 years ago to the day. Haven't regreted it yet. One things for sure, driver support sure has gotten better.
