that accidentally to a Mac SE. :-( I was trying to remove a
cable from the innards and my hand slipped and wacked the board on the
back of the CRT and skewed it far enough to bust that little tit.
Do you know how many of those week lost at Queens Park?? One guy in my
department nailed CRTs 2 in one week... You never forget that "hissing"
sound that comes out of the unit... then the expression on the person
working on it. > drive wouldn't spin up he would beat the crap

replace all the flaky hard drives free immediately.
I still have a Quantum PD1800S that has stiction. I paid $1100 for it new
and they didn't consider it to be a warrantable problem. I'll never buy
them again.
Hmmm... Not a warranty problem?? They certainly changed their minds when I
called them. It would not look good publicly for Quantum showing the Premier
of Ontario beating the hell out of one to start it up.
This brings back really funny memories. Every so often I'd get called out to
in the hallway (did not do tech support but people still asked for help)...
for help because someone had an unhappy SE. It would shock them to watch me
come up to their Mac and punch it really hard. [you *had* to see their
faces.]. Then. hear the drive spin up and walk away.
Those quantum drives were awful. As back up policies were rarely adhered to
it was my job to pull the drives apart and get the data out at any cost....
One day one the ministries lost some serious data to a dead quantum.. I took
a new one off the shelf and used some of its parts to make the old one work
(were talking replacing the motor). A rep and engineer from quantum came by
to see what I was doing.... They weren't going to replace the new drive that
I had cannibalized until they were told we had enough of their broken
garbage..

Me too! Except that is generic mono monitor. The chassis was too
flexiable and it tipped down, slewing that CRT board. Snap+hiss!
Replaced it at my expenese out of my only working monitor. :-O

That punching that thing is what jarred free those grabby platters.
That is only treating the symtoms. The true fix is new HD and
new 3.9uF 250V NP cap & yoke male connector, resolder the
trouble spots. Use screensaver always. Customers pays the backup
job and teach them to do it regliously.

It wasn't the quantum's problems. I see Conners and few others that
were being cooking inside those hot boxens without good cooling go
bad. The best solution is cooler running HDs for those boxens that
do have poor cooling design.

Wow. HOW on earth that is possible!? the motor spindle casing is
pressed into spindle axle. That casing has to go in order to get at
coil assembly. Yes I played with those dead quantum 40S, 80S and any
105S HH 3.5" ones that used both optical + sectors feedback
tracking. These dead ones died bec of grabby platters getting too
great to overcome and platters starts to lose data bits and the
bearings were still good and like new. Those ones that overheated
platters looks defect-free, no 4-pits and no crash trackings but
difference is it lost the surface lube/finish.
Even fabled Barracudas die from heat. I recently aquired one that is
still good (ST12550N) and experimented on it. Heated up like mad
without airflow. Still will heat up even case w/ hd inside with some
airflow. Noted that and knew this by reputation and I put a muffin
fan at front end blowing on the "steel cage" and allowing free air
rush across the top circuit. Cool temp as it should be with this
simple fan solution.
I still have a Quantum PD1800S that has stiction. I paid $1100 for
it new and they didn't consider it to be a warrantable problem.
I'll never buy from them again.

Ethan, my curious: that HD, did it run hot or bit too much warm?
That is the primary problem. PD1800S is old design and runs hot.
Did that HD sit all cooped up behind bezel or internally?
My HDs now are mounted in new ways with bigger open or 3.5" bezel
left off and they run at room temp or less. INCLUDING that "new" WD
9.1GB expert 7200rpm. The old LPS 540 is still living daily serving
as data archival along with bit more warmer fireball EX. CR, CX and
any fireballs run bit more warm or hot when cooling is poor.
