I recently bought a Samsung Book 8 Windows 8 and replaced the 1 TB hard drive with a solid state drive. I put the 1 TB hard drive in a case, planning to use it as an external drive for backup. However, my laptop won't recognize the drive. I also tried attaching it to my PC, but it wasn't recognized there either. I took it to the place where I bought the case, and they were able to see the drive & named it J. Obviously I'm not very experienced with hardware, but am hoping it's something simple. Thanks.
