Check your 'config.sys' file for a statement that says:

lastdrive=c:

(This assumes you have drives A, B, and C)
If I recall correctly, with DOS 3.n, you need to include that statement
in the config.sys file in order for the computer to know how many drives
you actually have.  You may want to check this out in your DOS manual to
double check my syntax.  (I don't have any manuals at hand right now.)
