Problem with HD bay 1 on QNAP 231+

Hi,

one of the two bay of my QNAP 231+ seems to be fault.

In the beginning i thought was due to SSD HD fault because with disc connected on bay 1 initial power-on test fail and nas wouldn’t even start. But changing to bay 2 same SSD disc, NAS startup without problems.

There are some things that i can do to try to fix it?

thank you very much

Sounds like a failed mosfet
