Sounds like you're talking about el cheapo drives that uses voice
coil? What I saw so far is usually few mech/coils/ failure and
most boards/platter/heads/bearings failures especially that Maxtor.

Thanks...I thought so too and still wished Seagate learned better
BUT past is past but not with rebranded "Conner" of their low end is
still begging for trouble. :)

Your assertion about smaller is better yes, in many ways but not

Your tips about LLF/temp. Yes, I did too.

My god, reliable, massive, trumping hd! :)) Quantum still is making
good drives and very reliable even to low end ones. Wow. Reason I
kept suggesting mid to high end is for performance wise.

> Your list of drive ripped open....
Did: nearly all Seagate series, few CDC, few Imipris, lots
Miniscribe, few Mircropolis, lots Kalok (virtual clone of ST225,
huh!), Kocera, lots of Conner of any kinds and oddballs including
2.5" , WD very few. Did Microscience, IMI, lots of Maxtor, Toshiba,
odd ball JVC's, Nec yuk!
One comment, DEC never make their hd's far as I was concerned,
contracted out to anyone willing to do it for Dec's biddings. :(
Once, I got a RZ23 scsi, can't use it on pc, returned back. If
there's was a way to make this work, great!
 
> I have an st238 that refuses to die!
That's ST225 serie with RLL, odd 26 sectors, ST250R uses 31 sectors
by 771 I think.

> Allison's advices of cleaning/smaller is better stuff...
Still they require good cooling anyway.

Really? Several suggestions: If you add more fans to monitors, turn
off unneeded lights, close the sun-lit window and few uneeded
equipment, you will cut down the heat. When I ran my monitor w/o
fans my bedroom feel hotter; with fans on monitor, room felt cooler.
Both of my pc and monitor is there.

Thanks!

I am hearing the noisy fans on monitor, one fan blowing into is
pulled from dumptered dec rainbow (sorry!) and a PC fan on top
pulling hot air out.

Those fools...I quote again: "no user
serviceable inside..." angry hiss. Simply tell users if they want
anything altered, ask tech people to do it instead! The fan can be
flipped around.

Allison's ranting about back up stuff...yes right, I know.
