Listen, Frank, aparrently you only partially know what YOUR're talking
about. You automaticially assume that because you were a brave little fellow
and took apart YOUR PC, you know everything about the computer world. Let us
remember that in older IDE drives, you could NOT have more than one device
per controller. This is because on some IDE drives, the on disk controller
could not be shut off to allow another controller to become the MASTER. So
you needed another IDE bus for another drive. Granted most PC motherboards
waste their time putting two EIDE interfaces on the board, but MAC's use one
fast, dependable, STANDARD interface we like to call SCSI (which supports a
LOT more than just hard drives and CD-ROM drives). And there are 6 devices
per BUS, not 7 (remember, the host adapter uses ID #7) (...unless you're
dealing with SCSI-3, or optical SCSI, but on a 5200, I doubt it). Plus he
said to use an External SCSI if, and I quote, "...you'd like to keep your
existing drive". Maybe you're not familiar with this little law of the
universe that states no two bodies can occupy the same space at the same
time, but in the compact world of Macintosh chassis' this could not be more
evident. Especially when trying to squeeze two hard disks, a CD-ROM disk,
15" monitor,  plus all the other integrated goodies in a space of roughly
1.85 square feet. But fear not, you can attach any SCSI device externally
with absolutely no cost to the data transfer (unless your dealing with
drives faster than 10mb/s unlogicially).  Oh, and another thing, on a mac,
Logical Block Adressing (LBR) is required, and guess what? IDE wont do that
for ya, baby - just EIDE.

So maybee you should take some courses, or better yet, get "Mac Hardware for
Dummies" at your local bookstore... you MIGHT learn something... =)
