Overheating hard drives hddtemp, data loss

[rokytnji]

If me. I'd unplug the drives and check connectors for dirt or looseness first. But I do not think that might be the problem here.
I have been picking up free computers from my local city hall IT support tech who is upgrading the city offices.

I have seen all kinds of wrong unusual things with these computers. So far I have accomplished getting 3 out of 5 fully functional,
with the Dell T3400 purring like a kitten.

From dirt to loose connections to pulling cpus, hard drives, ram, and power supply connectors.
It took some elbow grease to tune these up right.

Since you are the only one dealing with this issue on multiple computers.
I'd actually start wondering about the transformer to outlet electrical consistency.

MY place is 3 phase. When the fuse on the pole broke for one of my phase feeds to my place.
My central A/C units compressors ran hot as hell and shut down. I scratched my head till
I broke out my multi-meter.

Heat electrically is attributed to loose connections or no connection according to ohms law or resistence.
You might have to start looking outside of the computer room maybe.
