	AX = 4405h
	BL = drive number (00h = default, 01h = A:, etc)
	CX = 000Ah (size of DSPACKET structure)
	DS:DX -&gt; DSPACKET structure (see <a href=../../it/37/15.html>#01537</a>)
Return: CF clear if IOCTL successful -- check DSPACKET for actual status
	    AX = number of bytes actually transferred
	CF set on error
	    AX = error code (01h,05h,06h,0Dh) (see <a href=../../it/80/16.html>#01680</a> at AH=59h/BX=0000h)
Note:	this call is identical to the documented AX=4404h
