Recently,I had a problem with my floppy drive,so I replaced it with another one from a computer no longer used.When I look under “My Computer”,it shows 2 floppy drives,one as the A:drive and another as an F:drive.I try to read a disc in the one,but neither of them say anything is on the disc.I went into DOS,and it was able to read what was on the floppy(A:drive).How do I get my system to recognize my flopyp drive,and how do I delete the extra F:drive on “My Computer”?
