Re: URGENT: ATAPI testing needed for 2.6

[Chris Cappuccio <chris@dqc.org>]

Perhaps I should add this to the FAQ ---
sometimes error messages like this do not refer to a software problem, 
they refer to a hardware problem, but not a fatal one, just a jumper
misconfiguration

Some hard disks like Western Digitals (and *not* Maxtors, for
instance) require that you set the jumpers for *different* settings for a
single drive then you have for a master drive when a slave is attached.  You
can attach a second drive (or CDROM) when a western digital is set as a
single drive (not master) and it will work but you will get errors exactly as
you describe.  

So, verify your jumpers are set right !
