    drive letter dancing

    A poser for y'all <img src=/S/headthrob.gif border=0 alt=headthrob width=15 height=15>

    My home built box.
    Athlon/Via chipset.
    Two maxtor hard drives 40 gb, and 8 gb.
    A Promise Ultra ATA/100 PCI controller.

    The 40 drive is partitioned into 4 slices.
    The 8 drive has no slices.

    when plugged into MB the drive letter parade goes:

    C (40 p1) D (8) E (40 p2) F (40 p3) G (40 p4)

    plugged into controller:

    C (40 p1) D (40 p2) E (40 p3) F (40 p4) G (8)

    and the 8 drive can't be seen anywhere but windows.
    Now, I know why it can't be seen, no real mode drivers. Apparently
    they don't exist. But why the letter jump?

    I'd have to assume that Windows assigned the first set of letters in it's own mystical way and the controller assigned the second set according to how it was programmed. <img src=/S/shrug.gif border=0 alt=shrug width=39 height=15>

    <hr>...the 8 drive can't be seen anywhere but windows...<hr>
    What does the BIOS say about the drives? I guess it's possible that you may have the jumpers on the 8 gig set incorrectly.

    As far as I know, Windows has always assigned drive letters, starting with C, to the first partition on each PHYSICAL drive and then to additional partitions, starting with drive 0 (zero). So, the assignment you get from the motherboard connection is what I would expect. Of course, altering that assignment could be done by Windows or the Promise card.

    You need to specify the Partition types. I think that Windows displays Active Partitions first, followed by Primary partitions, then Logical drives in Extended partitions.

    Did you create an Extended partition after you created C: and the rest of the logical drives are off it or you just created primary partitions and activated one of them (the C?
