Heat Stress Test

It was a bit annoying to open this device as the heat had deformed it and I couldn’t unscrew all of the bolts. I ended up having to clamp the plates together in order to relieve enough pressure to unscrew them.

Once I opened the device, it was clear there was no data loss.

Corrosion Stress Test

No data loss.

Crush Stress Test

Warping can also make it pretty tough to actually unscrew the bolts.

Opening the device shows no data loss.
