This is regarding one of my cache drives named cache_ssd (500GB). I use this only for downloads. I had multiple downloads and seed going on and it was not full or anything. But now it keeps going offline. There are some errors on the syslog which I didn't understand.

Is this drive corrupted or am I doing something wrong ? 

Diagnostics zip attached.

Looks more like a power/connection problem, check/replace cables and see if all the errors like these go away:
