5.25 Floppy Troubles

I have just installed a 5.25 floppy drive on my Windows XP machine.  (It came from an old Zenith 386, circa 1987).  BIOS and WinXP recognize it, it functions properly (I have some 5.25 disks, 160K FTW!), it reads disks and formats them ok.

The drive light just stays on, however.  It doesn't turn off when there is no drive access.  Any ideas on how to fix that?

I have two 5.25" floppy disk drives somewhere in my junk room, I can read them. BTW, widely used 5.25" disks are 360 KB if low density, and 1.2 MB if high density, and they are faster and more reliable than Sony's 3.5" bullshit they introduced.
