Hello LTN, I’m sorry for the inconvenience that you have faced with your system.
I would recommend you checking this thread from a user who was having the same issue. https://communities.intel.com/thread/54282
I tested the following devices on my NUC and these are the results:
- Crucial SSD 2.5 was recognized.
- Fujitsu HD 2.5 was recognized.
These 2 products use 5v.
The only device that did not work was a regular mechanical 3.5 hard drive, but once I connected the HD to a power supply, it worked without problems. These HDs required 12v.
I’m using BIOS version 0027. This could be a compatibility problem with the HD you are using.
