Adding hard disk drive to 6386WGS

[J.S.BOSTAK]

I am trying to add a second _internal_ hard drive to my 6386WGS.
I have the following questions:

1)  Does anyone know if my power supply can handle the additional
    drive?  The original drive is a 30MB drive (full-height, side-
    mounted Micropolis, I think) , and I am adding
    a Seagate ST251-1.  I don't think the +5V should be a problem,
    but I am worrying about steady-state and transient current
    on +/- 12V.

2)  Does AT&T support this add-on procedure by selling power bus
    cables with connectors (at least 4 connectors--one for the
    power supply, two for the hard disks, and one for the floppy).

Since I don't read this newsgroup regularly, could you send responses
to:

Thank you.
