Yes, I know somewhat about the possibility of data corruption if there was data that hadn't been all written to it.
But I just saw this:
Note:If u remove HDD(not USB sticks) without safely removing it,its not healthy and will affect life.
So, if nothing is actually writing to it, could there actually be any harm caused by not safely removing or unmounting it before disconnecting it?
By the way, if I'm way off about any of this, please correct me.
