I have a 8tb my book duo. I just moved and was extremely careful with the drive. I didn’t even put it in a box, hand carried it. It was working perfectly fine at old place. I plugged it in at new place and I have 3 blinking red lights. Normally I hear the whirring sound of it starting up and there is no sound. I’m wondering if I bought a new plastic housing of ebay and dropped the old drives in would that fix it. I cant loose this data.
any help would be greatly appreciated. (please note that I am not a techie so any help needs to spelled out in dummy language 
)
