Why do hard drive heads get stuck?
Why do hard drive heads get stuck?
Sometimes the heads stick to the platters like 2 pieces of glass will. This will make the spindle motor unable to spin up the platters the next time the drive is turned on. It seems that this usually happens when the drive is fairly hot, then when the drive is shut down, the rapid cooling makes the heads stick.

Why does my hard drive spin down/Park?
The external inclosure itself is not causing the drive to spin down/park the head, but the HDD itself, as I have tested with my server grade RE3.
