IDE Slave Removed, IDE Master Not Recognized

Hello,

There was a PATA hard drive (slave) attached to the same IDE cable as
my DVD burner (master). The slave hard drive was removed, and nothing
else was changed. Now when the computer boots, the DVD burner is not
recognized in the BIOS.

Every jumper / cable / channel setting has been tried, and even my BIOS
has been flashed. The previous hard drive was added back in to the
equation in its previous position, and neither device was recognized.
The board is an ABit AI7, and the primary hard drive is a WD Raptor
(SATA) attached on SATA1.

How do I get the DVD burner to be recognized again?

Thanks,
Mike Jones!

 

does it show up on the BIOS start up screen ? try a new cable ?

 

are you using an 80 conductor ribbon with the blue end of the ribbon
connected to the mobo and the master device on the other end (NOT in the
middle) of the ribbon? any other ribbon cable configuration, as far as
position of the drive on the cable, is not a valid configuration.

tried jumpering the DVD drive as Cable Select?

 

It ended up being the cable. Sorry that this was not checked earlier.
I also found a similar thread on [H]ardForums that had several
suggestions (in case someone comes across this posting in the future).
The thread is at http://hardforum.com/showthread.php?p=1029645123

Thanks,
Mike Jones!

 

glad you got it sorted...

 

Why does the blue end need to conected to the mobo ???

Just like to know

Thanks.

For Cable Select (CS), the position of the drive on the cable determines
which drive is recognized as Master and which as Slave.

The signal line governing this selection is present in the Blue connector
and is terminated at the Gray connector. For this reason, the Blue
connector goes to the motherboard.

The Black connector at the other end goes to the Master drive.

The Gray connector in the middle goes to the Slave drive.

On many UDMA cables, you'll also notice that there is a greater distance
between the Blue connector and the Gray connector than there is between the
Black connector and the Gray connector. This is to facilitate snaking the
cable for the best possible air flow inside the case. You mount the Master
and Slave drives right together, so there's no need for a lot of cable
between them (and, therefore, you don't want a lot of slack in the cable).

If you are jumpering the drives as Master (MA) and Slave (SL), as opposed to
Cable Select (CS), the position on the cable is irrelevant .. though it
still makes sense, for best air flow, to connect the Blue connector to the
motherboard.

the cable is made such that the conductors "expect" the blue end to the
mobo. if the devices are jumpered as cable select, and maybe even if they
are jumpered as master/slave, then you will have problems if they are not in
the correct positions on the cable. I have had issues with master/slave
jumpering AND Cable Select jumpering with a single drive in the middle as
opposed to on the end where it belongs.

 

I did have a problem with a computer I was troubleshooting where the drive
would not appear, jumpered as Master, when installed on the middle of the
cable... go figure.

Probably the exception, rather than the rule, but I've always advised to go
with the UDMA CS "rules" nonetheless.
