what about compact flash drives, which are IDEish in
nature. Im all for authenticity, but if a solution
presents itself, and Ill add one that may not be as
volatile as magnetic media, Im equally gung-ho. Hey
lookit, I just became a ho LOL LOL. Albeit cflash
cards are themselves being phasored out (in favor of
the smaller sd and xd nuisances). But theyre very
cheap too...128megs ~ $10. Or 1gig for 25 after a
rebate.

"Boardswapping" a

Sure, but the HDAs are not exactly home-repairable
either.

But as you said, the electroncis is rarely the
problem.
One caveat in doing this is that I beleive some
drives stored HDA
parameters (bad block lists, etc) in non-volatile
memory on the logic
board. Swapping boards between seemingly identical
drives won't always work.

Having looked at some IDE drives I am not sure I do pitch connections (tht I probably could solder if I
had to) and nasty
ASICs that I can't get and don't understand. I
would
attempt to replace
standard components if I could prove that was the
problem.

5 years is not that long.

That's a good enough reason for me _not_ to design anything using them.
Flash memoery has a limited (albeit large) number of write cycles, and I
am not going to design something round a product that is (a) going to be
hard to find and (b) haev a limited working life anyway.

well...it's a solution. It's been done for the Commie
64 amongst other things. I have to believe one would
have a longevity at least that of an IDE hard drive
(in particular a drive that's already years old!). If
they fall off the market entirely in fire years,
that's five years you have to scarf up all the deals
you can find. I already see the smaller ones going for
a tenner.
Nuts and Volts magazine had an article within the
last 6 months I believe wherein the construction of an
mpeg player was detailed, which used flash storage.
Didn't buy it, but afterwards thought it might prove a
useful read if I ever wanted to design a reader of my
own. I may not be the sharpest tool in the shed, but
there didn't seem to be anything terribly complex
about it. Can't even remember what the circuit used
for brain power, but it must have been something
common and well documented.

Uses CF cards.

I did buy one - very happy with it. Some SMT, which tends to scare
off some people, but all in all, an easy kit to build, with
easy-to-get parts (as of Nov, 2005). I was happy to have a 20x4 LCD
display on hand ($5 at a hamfest), and the exact shaft encoder in the
plans (there are others, even cheaper ones, but it was nice to have
the right one in my parts bin - from the Dayton Hamvention, years
ago). I did have to get the CPU and MP3 decoder and DAC new, but they
were easy to order from Digikey, et al.
