Hello --

	I have a 25 MHz 386 clone running SCO XENIX-386 2.3.3 (I bought
2.3.2 and upgraded it with UFJ and various other SCO SLS's).  I have a
WD1006V-SR2 RLL hard/floppy disk controller.  I am having problems
writing to my 1.2 and 1.44 Mb floppies and the symptoms are these:

	-	I can format and verify the disks with the SCO format
		command.
	-	mkfs will create a filesystem on the floppy.
	-	fsck often *BOMBS* thereafter on the newly-created
		file system.

Sometimes things are alright after the mkfs, but if I use the copy(C)
command to copy directory hierarchies to the floppy, fsck will bomb.
Additional wierdness follows:

	-	Everything works fine if I use stinking DOS.
	-	Using cp(C) does not seem to produce these problems.
	-	Using dump(C) will provide an error-free backup.
	-	Using dd(C) to copy disks will produce a thoroughly
		screwed up image copy.

Am I using a non-supported RLL controller?  Are there bugs in the
update SLS's?  Thanks in advance for any help.

						John
