All,

During POST i get the message,'primary slave device ATAPI
incompatibility' error.

So I dont get to see my HL DT ST GCE 8320B LG CDwriter in
Windows XP.

I have looked high and low for a way to solve this, but
to no avail. The drive is only a year or so old. There
is no firmware update for it! It worked in my old PC,
before I rebuilt a new box today!

Any ideas wold be greatly appreciated.

Plz email answers to me.

It is a bit unusual to put a slow-speed device like a CD drive on the
primary IDE controller. That is usually used for hard drives. If you have
a secondary IDE controller, and many motherboards do, try connecting the CD
drive to it.

Also, did you set the jumpers on the CD drive correctly, meaning slave vs
master?
 
Hi,

On the primary ide I have a boot drive, and cdriter as
slave - jumpers correct.
I have the a HDD as secondary master, and dvdwriter as
secondary slave on the secondary ide connector.

Tried all jumper settings, cables etc...
 
In general... Don't put a CD, CD burner, DVD, or DVD burner on the same
IDE channel as a hard drive. IDE will transfer data at the maximum speed
allowed by the "slowest" device (e.g. much slower than your hard drive can
transfer data).

In general...CD writers and DVD writers are not happy being slaves. Some,
indeed, will not function properly as a slave.

All,

Thx 4 advice so far!

Should I then have my two ide hard drives on one channel,
and my two cd drives on the other?
I thought that was bad practice!

CeNo.

Uh, that was good advice ten years ago. But all recent (and even
fairly recent) PCs maintain independent speed tables for each device
on each IDE cable, so that having a slow widget on the same cable
with a fast widget will not affect the speed of the fast widget.

It is true, since IDE only transfers to one device at a time, that
using a slow widget means that a fast widget with which it shares
the IDE cable will need to wait a bit longer for the slow device to
complete its transfer, but that is a second-order effect.
