Hard Disk for PC-6300

[PAX at PSUVMA.BITNET]

I'm thinking about putting hard disks in my PC-6300's.  They currently have
2-360k floppies.  My first question is should I go with AT&T hard drives or
a third party manufacturer.  I've heard about problems with AT&T's drives.
My second question is terminology.  I've talked to some people, and they said
I should look into "plated" disk drives, and ones that have "disk parking".
These terms are foreign to me, so if you know what they are, please let me
know.
   What do you think about half-height hard drives over 3-1/2" slot hard
disks?

   Please respond to this newsgroup, or to me direct E-mail.
