CAUSE
This problem occurs on disks that do not contain a media descriptor byte in the BIOS parameter block (BPB) of the boot sector. Some older preformatted floppy disks do not contain a media descriptor byte. Older product disks may also not have the media descriptor byte.

It's not a driver problem.

When a floppy disk is formatted, it has a piece of information put at the beginning of the disk. Older disks may not have this piece of information, and therefore XP64 can't properly read the disk. This actually goes all the way back to NT4, and probably 3.51.

Are you trying to read very old disks? They may just have gone bad if they are very old. I haven't owned a floppy drive in about 10 years, and I remember even then alot of disks I had were unreadable or had errors.

(floppy drives in 2007.. amazing)

I found out what the real problem was . the end of the ribbon that attaches to the motherboard from the floppy was on backwards . also i take too many perscription drugs .
