Problem with formatting/won't recognize C

By tiredxsunrise

  1. I'm trying to format my C drive (something I've done a million times before, so I know what I am doing.. But it's the first time on this computer), but once I reach the menu (after starting up the computer from CDrom), my C drive is NOT on the list. It does list my secondary harddrive as my C drive, strangely enough (I can tell it's not actually my C drive because of the size and brand name).

    Then I tried just going into DOS with a startupdisk, and just typing format C.. but then it tells me invalid command/ C can't be detected.

    Anyone know what's causing this and how I can solve it?

    Thanks a lot for your help & time, very much appreciated!

    Could you boot up into the drive? Or is that why you're trying to reformat?

    I can't remember, but I don't think you can format a "drive" that's been partitioned in NTFS with Windows 2000/XP without deleting the partitions.

    What version of Windows have you been running?

    How many physical HDD's are on this system and how many partitions each drive ? ?
    Post your drive layout and we can go further...
    Also the file systems on each.

    I might add that if your drive is a SATA drive, XP setup won't be able to see it unless you press F6 at the begining of setup and load the proper SATA driver from a floppy.
