Multiple hard drives show up in Explorer

  1. OS: Windows XP Pro

    I have 3 hard drives all 80GB, two are from Western Dig and one is a Maxtor and 1 DVD attached as follows.

    Primary IDE channel with the 80 wire cable set up:

    Drive #1 (OS drive) - jumper on Master w Slave Present, end cable location, assigned to C:
    Drive #2 (data drive) - jumper on Slave, middle cable location, assigned to D:

    Secondary IDE channel with 40 wire cable set up:

    Drive #3 (DVD) - jumper on Slave, end cable location, assigned to F:
    Drive #4 (data drive) - jumper on Master w Slave Present, middle cable location, assigned to E: and G:

    I don't know why the same drive #4 gets assigned to two letters E and G???

    How to fix so it is only assigned to one letter???

    I am taking my setup info from: www.mikeshardware.com in the how to connect IDE drives section

    The only question that springs to mind is, "is there a partition on the drive"?

    I don't have a partition on that drive and the folders/files under each E: and G: are identical.

    Reread that Mike's Hardware article. Pay attention to the number of wires in the cable. The (I think) reverse slave master relationship on the second IDE channel was written for 40 wire cables, which I doubt that you have.

    Of course I do have a bit of trouble with reading comprehension, I used to work for the post office.

    If you have full access to either drive letter for the same drive, I cautiously suggest that you might just remove one of the letters in disc management.

    LOL and so did I (once work at the post office)! :D

    @512dude
    Yep. Now i can plainly see what you said and agree. Driver letters E and G are mapped to the same Volume name and serial numbers.

    So the "curiouser" question (is that a word?) is how did two drive letters get assigned to the same volume (personally, didn't know that was possible). Do these two drives appear in disk management? I join the captain as well in cautiously looking at Disk Management to remove one of the letter assignment

    I did see that and I do have an 80 wire cable on the Primary Channel and a 40 on the Secondary Channel; I just counted them to be sure. The 80 wire cable has much smaller diameter wires than the 40.

    Rt click My Computer->Manage->Disk Management

    That seemed to do it, I removed the drive letter assigned under Disk Management and voila there is no additional drive showing up.

    Thanks guys and too bad for the posties you aren't with them anymore. :)

    Cheerio! Seattle out...
