I'm attempting to add a new 120 GB HD to my WinXP computer.  I currently only have one hard drive installed.  But Disk Management shows two volumes:

VOLUME   Layout    TYPE    FileSystem  Status
(blank)   Partition   Basic   FAT                Healthy (EISA Config.)
(C)             Partition   Basic   NFTS              Healthy (System)

The C: volume listed above is my ACTUAL hard drive and operating system, which was formatted with NFTS.  Right-clicking on C: under Disk Management brings up a full pop-up menu.  But when I right-click on the blank volume to try to delete it, a very short menu pops up.  The only item on this menu is "Help", with a horizontal line above the word "Help".  It appears that this pop-up menu just contains the very last item of the full pop-up menu that I can get by clicking on the C: volume.   The blank volume is described by the Disk Manager as a 39 MB drive, which is a similar size to a an old HD I had tried to INSTALL as a second drive (but gave up) when I first set up the computer.

I have tried installing the new 120 GB hard drive, but the computer doesn't recognize the new drive, and it has no affect on Disk Management.  I've double-checked the jumper settings, and I don't think that is the problem.   How can I clear the "phantom drive" from the Disk Manager?Computer make.model can be significant as for instance many Dells require CS rather than master slave, etc.

I am assuming this is an older computer with a hidden EISA configuration utility. PLEASE leave that alone unless you know what you're doing.

When the new drive gets recognized by the BIOS correctly it should show up as D. Don't mess with C unless you want to start all over again!!
