I plan on getting a new hard disk for my 7300.  I was wondering
whether people had any recommendations for internal (half-height) 30
to 40 meg drives.  I would prefer to keep it all in one box (ie avoid
external drives or supplies).  I have been considering the seagate
ST138 or ST251, preferably the fast (28ms) version of the ST251
(ST251-1).  I however have two concerns. First, will these drives
suffer from the oft-mentionned problem of not spinning up when turned
on? I have heard repeatedly that the ST251-0 has this problem, but
does the ST251-1 or ST138 series have this problem. Secondly, I am
very concerned about power requirements and heat dissipation. In
particular, the ST251-1 draws 2.4 amps off the 12 volt supply on
startup but then settles down to about an amp or less during typ.
operation, if memory serves me (I am sure about the 2.4 amps). The
draw on the 5V supply is also under an amp. Is the 7300 supply up to
the task? Will this 2.4 amps on startup be a problem?

In addition, if anyone has any personal experiences with either of
these drives or suggestions for an alternative drive, I would
appreciate the information.


Thanks
