Where did you hear that?  In most typical cases, hard drives
should always be the master, albeit PRI or SEC IDE port.
Making a 2nd HD a slave to a CDROM drive on the SEC IDE port;
benchmarks show decreased performance.

If it was a CDRW drive; sometimes CDRW drives must be the
master on the SEC IDE port, sometimes they don't need to be.
Depends on the CDRW drive.

Using your analogy:

>>Given the fact, that we have 2 horses and 2 super-chickens,
I think it's
>>obvious why we put the horses on the first hall and the
chickens at the
>>second.

This is exactly why the HD (horse) should be the master and
the CDROM drive (chicken) be the slave.  This is also why one
device per channel (port) is desirable, and a controller card
is best to use if a mobo only has 2 IDE ports and you wish to
add another HD if you already have an existing HD and CDROM
drive.  IDE devices always work best being a 'stand alone' on
an IDE port.  If they are not, even regardless of how they
are 'jumpered', performance decreases.

Doug, since it's no big deal to change them around, test it
yourself.  Jump the new HD as the SEC master and the CDROM
drive as the SEC slave, and run a benchmark (with SiSoft
Sandra for example).  Then reverse them (being sure to change
the jumpers accordingly and remove them both from the device
manager first) and run the test again.  You may get a more
accurate test by 'copying' a ~100mb or so file size, then
compare the times.

FYI, a quick random search shows:

"i.e. if there is a CD-ROM drive on the cable
you are putting it on, you will want to change
the CD-ROM drive to slave and set the new
hard drive as master."

Probably.

No. The disk will not work at full speed.
