I have a WD Green 2TB which was working perfect until I've put it in a new case which doesn't use the standard screw system to fix the drives, but instead uses these plastic HDD trays which doesn't seem to be tight enough for its moving parts.
So after I've moved everything to the new case (Sentey Triac) my HD started to disappear from Windows after a while and won't appear again until rebooting the computer. Mostly after I put it to do some reading/writing as it's not my system drive, but a storage one. System drive is a SSD and works just fine in one of those trays.
This has been driving me crazy these past few days thinking it could be the HD failing, Windows fault or even the new PSU I got with the case. I'm pretty confident that the HD is not dying yet, it's not a Windows problem and the new PSU has nothing to do with it.
So I decided to remove the HD from the tray and put it on a cloth right on the floor.
I'm backuping everything in the drive just in case and also running some health checks. It's been a few hours without problem (still on the floor), much more than I could go through with the drive in the case tray.
Could that really be the problem? Have you heard something like this before?
