I'm getting rid of some old hard drives & I'm trying to extract some of the files off of them before I throw them out, I'm using a Bytecc super speed USB 3.0 docking cable. After connecting it to my laptop (Win 7 OS) it comes up for about a couple of seconds & then says I need to format the drive before the laptop can read it. I don't want to format before I transfer all the files I need off of it.
