I agree about the power usage part. I did shop all the drive specs when I
upgraded my 6-gig Fujitsu to a 30-gig Toshiba, some time ago. I thought I chose
one of the lower power consuming drives (and perhaps I did) but I think it draws
a little more current at startup than my old one does because I've noticed a
decrease in usable battery life. What happens is that eventually that batteries
run down to the point where when it has to spin up the drive, the voltage drops
too much and the JB goes into pause mode. There is actually a fair amount of
capacity left in the batteries at this point because the JB will sit there in
pause mode for a long time, sometimes hours, yet does not have the "cranking
amps" to spin up the drive. So I recommend choosing a drive that has the lowest
spin-up maximum current draw. I would think this would mean a single platter
drive (assuming they can squeeze more than one platter in those tiny things) and
a slower (4200-RPM) unit.

Related idea:

Although one of the reasons I still have and use my old JB6K (now a JB30)
besides the fact it still works, runs Rockbox, and uses cheap common batteries
is the high storage capacities you can achieve with these at low cost. That
said, I've also been playing around with solid-state-flash drives in the
compact-flash (CF) form factor, plugging them into a cheap (like $5 USD Ebay
specials) CF-to-2.5"IDE drive adapters. I then plug that into a laptop
replacing its mechanical IDE hard drive. The result, other than its totally
silent operation, is much longer battery life. (Yea I know about watching out
about too many erase cycles when using the SSD as an operating system drive, but
I'm working on minimizing this). Anyway, these things are starting to really
come down in price as I recently bought an 8-Gig for $40 USD inc/shipping. Some
JB users might want to consider such an upgrade if they aren't just trying to go
for the most storage they can get. I think you can get
64-Gig CF drives, but currently at a high price. Because the spin-up surge
seems to be what stops the JB fairly early on in the battery discharge cycle, I
would not be surprised if you could get 3 times or more play time on batteries
if you had one of these in your JB instead of the old hard drive. You could
treat the unit a little rougher too since there are no heads to crash (other
than your own!).

I've also got one of those cheap, tiny, & common Sigma-Tel based USB-flash 1-Gig
Drive / MP3 player/recorder/radio combo units and marvel how it plays for over
12 hours on a single AAA NiMh battery.

Pick the drive you like - I used to like a - then b (their jumpers were better)
- Now I like drives made by c (price maybe) . but for no good reason - I have a
80 gig in mine I forgot who made it!!

Subject: [archosjukebox6000] Largest hard drive that is usable?

I was thinking about swapping the hard drive
for something larger 80GB or higher.

Is there any info on which drives will work?

Anyone have problems with Seagate drives? (My
preferred manufacturer)
