RE: Pri Slave Drive ATAPI Incompatible

If the hard drive & CD ROM are each alone on their IDE cables, check to
see if thay have a Cable Select (or something similar) jumper setting.
Some drives prefer that  vs. master-slave/primary-secondary when they're
the only device on the cable.

If they are sharing a cable, try dropping to just one device for
troubleshooting.

If you brought the IDE cable(s) from PC1 to PC2, try using the ones that
came with PC2 as some IDE cables don't work well outside their original
machines.

If the cable(s) are >18 inches long, go buy new cables as they are
outside of spec.  (Yes, I know you can buy longer cables and higher
quality cables can be 36" long, but you take chances when you leave the
spec)

And finally on cables, put the Master/Primary at the end of the cable &
the Slave/Secondary in the middle.  While specs say it doesn't matter,
sometimes it does.  

Go into the BIOS and put drive settings to "auto".  Try PIO mode for the
CD if it won't work in DMA mode.

If all of the above doesn't solve it, we can take a look at the rest of
the PC.  How big is the power supply and what other components are in
PC2?  What brand/model mobo does PC2 have?

Subject: [PCTECH] Pri Slave Drive ATAPI Incompatible

I replaced the system board, processor, and memory in PC 1 and used the
old parts to build PC 2.  PC2 has a new hard drive and a CD drive from
PC1.  When I boot PC2 I get the error 'Pri Slave Drive ATAPI
Incompatible' on the CD drive along with a hard drive error.  I am
making the assumption at this time the HDD error is due to not being
formatted yet so I'm focusing on the ATAPI error.  The HDD tools are on
CD so I need to get the CD going to work on the HDD.

I have tried swapping cables, changing IDE controllers on the system
board, and switching from master to slave.  Nothing seems to help.  I
will probably try them all again this weekend just to make sure I cover
all the bases.

Does anyone have any experience with the 'Pri Slave Drive ATAPI
Incompatible' error?
