PowerBook G4 hard drive (& possibly more) replacement?

My (new to me) 1.33 GHz 15" G4 stared to buzz intermittently, more so
if I move it while it is running. I imagine this is a warning sign
that the hard drive is getting ready to fail.

The current drive is a 55.89 GB TOSHIBA MK6025GAS. The G4 has 2GB ram,
and seems to run a little hot (by touch; aluminum is a good
conductor). Should I stick with a 5400 rpm drive, or can go with a
7200 rpm without actually overheating? Any suggestions about a good
candidate for replacement? SSDs are still too pricey.

The optical drive is a MATSHITACD-RW CW-8123. Seems to work fine for
reading CDs. As long as I have the G4 opened up, I could upgrade the
optical drive as well. Again, suggestions for a good replacement
candidate will be much appreciated.h

While I have the case opened, are there any other upgrades or hacks I
might consider?

Thanks,
Larry

Dude! This is exactly what happened to me the other week! See the two
threads i started recently. The only difference is that my machine is 1.5
GHz, but it's of the type that also came out in 1.33 GHz.

When the true fail comes, you'll get a quite exciting chirp sound - starts
low and shoots up to ultrasonic in a fraction of a second. You're then
just hours away from needing a new drive.

You've made a backup, right?

I just bought a Seagate Momentus 7200.1 (which, as the name hints, is a
7200 rpm drive), at 100 GB, off the back of this review:

Sadly, they don't make the bigger sizes in PATA; 100 GB is still 20 GB up
from the current/last drive, though.

I haven't received it yet, and so haven't had a chance to see how hot or
loud it is. If you fancy waiting a week or so, i can let you know!

My understanding is that most of the heat dissipated by a laptop is from
the CPU and other bits of high-speed logic, not the hard disk (for
instance, if i set my machine doing modular exponentiation on huge numbers
in an endless loop, it reaches maximum heat - i did this on purpose to dry
some socks the other day). So, even if the disk puts out 50% more heat, it
won't make much of a difference to the machine's total heat output.

I got the superdrive as a factory option, and i've been very happy with
that - being able to play and burn DVDs is really nice.

Run a vacuum cleaner over it to take out any dust. Wave a dead chicken.
