I’ve purchased a 4TB WD Red HD 10 months ago, and experience heavy problems since. There are 2 partitions (1.7 TB & 1.9 TB) on it, and although the capacity is reported correct in win10, there appears only a tiny fraction to be usable (around 200-300 GB). When I transfer bigger files, win 10 suddenly freezes, or I get the error message that the disk is full.

WD Diag reports only 2199 GB available, also the HD is reported as USB drive instead of SAS. The SMART status appears not to work. In the properties, SAS is reported correct, health status has a warning, but tests come up without error.
I suspect there is something very wrong with the device, or it is not compatible with my system somehow (?)
