Hi friends. I have some 2tb external “My Book Essential”. there are usb2 and usb3 both.
I have some other external HDDs from other companies.
as I have many power supply (some 12v 2a and a few of them 12v 1.5a), I don’t know which adaptor is suitable for any hdd.
so I use 12v 2a adaptor to most of them.
my question is this can damage hdds?
If yes, which adaptors I have to use for 2tb My Book Essential (usb2 , usb3)?
