[Discuss] weird disk issues

[jack at coats.org (Jack Coats)]

I have a 'home server' and it is in a hall closet without a door.  It still
gets dusty and air circulation is poor.
I seem to have a thermal problem on occasion that keeps it from recognizing
an internal data drive
(not the boot drive) when it comes up.

I to have a UPS, but have found using and monitoring a good UPS is better
than some 'cheap' UPSes out there.
I use APC here at home that use 'real sign wave' output.  Some cheaper ones
do square wave or few steps in their
sign wave.  Yes, I used refurbished UPSes, with new batteries.

My systems tend to need a new power supply, even if on UPSes every 5 years,
3 if knock off supplies.
I have dissected the supplies a few times and it is pretty much  always a
electrolytic capacitor that fails.
Sometimes it will take a winding in a transformer with it.

The only UPS failures I have had were after a local lightening strike.
Opening up the UPS, it's power section
and half of the MOVs were apparently toast.  All equipment on each of my 5
UPSes passed without a glitch,
but 2 of the UPSes died in that strike.  The UPS guy hated me getting new
UPSes and batteries delivered
after that, but all has worked well. - Oh yes, I lost about $1000 on
non-UPS electronics plus the UPSes during
that incident.

Not sure if anything there will help.
