I have a 1.4 Meg floppy drive in an AT 80386 machine (AMI Bios).  The
drive is a Toshiba.  I am using a Western Digital dual hard floppy
controller.

Description of problem:
	boots fine off the drive, reads and writes to the drive.  However,
	if you take the disk out, replace it with another, and take a 
	directory, it gives you the directory of the first disk.  (It 
	doesn't reread the FAT area.).
	If you then switch to drive B, do a directory, and then move back
	to drive A, it then reads the directory fine (until you change disks).

	I have run PCTOOLS 5.1, and it won't recognize either drive upon
	initialization from floppy, but it does recognize the drives if
	you press <control>+drive letter (the usual way of changing between
	drives in PCTOOLS).

	In sum, it appears that the computer treats drive A like a hard drive.
	  
	I've tried both IBM DOS 3.3 and MS DOS 3.3 with the same results.
	The device=drivers.sys /d:0 doesn't work.  It only renames the drive
	to an external C drive (I havn't installed a hard disk yet).

Any help or suggestions would be greatly appreciated, especially a clue as to
whether it is the controller or the disk drive.

Thanks in advance,
Rusty
