HDMI In; video freezes after a period of time, audio is ok.

Transferring local material via the 'In' port, the recording video freezes after  between 20 to 60 minutes with the audio intack. Never had a problem before..

I re-load a fresh 'image' file, then updated the F/W with the latest version (v2.1.45, but NO difference except for the file sizes are now 2x the size they were before (separate problem)

I took the newer 4TB drive out and replaced it with the original 3TB (both WD 5400rpm, one 'Blue' the other 'Red) and made a number of 'test' recordings. NONE of the recordings failed..
I  ran a number of HDD tests on the 4TB and none failed! SMART tests (short and extended) all passed. A surface scan passes, no bad blocks. I re-installed that drive back in the x10 and ran more tests, so far no failures..

Any ideas since none of this makes sense.

I guess no one here uses or even tried to use all the features of this and the 2 models following this (Z10 & Z10 Pro) that have the same feature.
 
 I was also having a intermittent issue of playback stopping out of no where forcing me to restart the video. Every time, the location where the playback stopped played right thru with no issue. It did seem to increase after the unit was been in use for a longer period of time (say over 2 hours making me think it was a 'thermal' problem.
 
 In my list of troubleshooting I even swamped power supplies (can be a problem over a period of time with other devices), but there didn't seem to make any difference.

Apparently it was the SATA socket intermittent bad contact(s) that was the problem. Removing and re-inserting was enough to clear things up.
