Have you try Intr $21 function $1C yet?  Call with AH = $1C and DL is the drive
number in question (0=default, 1=A, 2=B, ...).  Look at the first byte of the
return at DS:BX, if it is $0F8 then it is harddisk.  It's worked for me... 
Something like:

	MOV	AH,1CH
	MOV	DL,03H		;drive code, 0 default, 1=A, 2=B, ...
	INT	21H
	CMP	BYTE PTR DS:[BX],0F8H
	JE	FIXED
	JMP	FLOPPY
FIXED:	.....

FLOPPY:	.....

should work, methink ;-}.
