I've got two hard drives running two different OS. I need both of them, but want to run them on separate drives without dealing with the struggle of switching the cables every time.
I suppose cutting the power of the HDD that's not in use should do the job(?). But when I stumbled upon this switch it specifically says:
[...] NOT to be used to for hard drives, optical drives, etc.
Disregarding potential problems with the BIOS that may occur, is there a physical issue that I'm missing here? Why should you not use that kind of switch for a hard drive?
