> Interesting. I use the WD Red drives, too, and recommend them. Your drive's smartctl report is clean as far as wear & tear is concerned. That suggests a hardware problem elsewhere in your system. Bad cable, perhaps, or a failing power supply.

To me, it looks like a power problem: 50 out of 177 power cycles are power losses:

>  12 Power_Cycle_Count       -O--CK   100   100   000    -    177
> 192 Power-Off_Retract_Count -O--CK   200   200   000    -    50

I had something like this in my system due to a bad SATA power split cable.
