[comp.sys.ibm.pc.hardware] Need help - PC recognizes drive D instead of C

luongt@tekig6.PEN.TEK.COM (Lu T.) (08/02/90)

	Hi,

	I have 2 IBM PCs, one portable has 20MB HD and one desktop has
	10MB HD, both of them have only one 360K floppy drive and one HD 
	default to C and they both work fine with DOS 3.30.

	Yesterday I swapped the HD (with controller card), and when I 
	powered it up, it said "Bad or missing Command Interpreter" so I
	booted it with floppy and now it recognizes HD as drive D instead 
	of C.  If I try to go to drive C then it says "Not ready error 
	reading drive C".  I didn't know what I did wrong so I swapped 
	HD back to original PC, but it still gives me the same error.

	What did I do wrong?  Any help will be deeply appreciated.

						Thank much.

I see two main possibilities here:

	1. The drive is configured as drive 1 instead of drive 0
	   (jumpers or dip switches on the drive for this),
or	2. The drive is plugged into the wrong connector on the 
	   controller cable, assuming you have one of those "twist"
	   cables.  My cable has a connector for drive 0, and another
	   for drive 1, and BOTH drive are jumpered identically (drive 0?)
	   .. the cable twist (some strands of the ribbon cable are twisted
	   between the drive 0/1 connectors) does the drive select for me.
