I have a MacBook pro and it stopped booting, Disk Utils couldn't mount the disk so I fitted a new Mac specific drive (I know there is no such thing but it came from a Mac dealer and sold as such)
it lasted about 3 weeks and the same again. I couldn't access when plugged into a USB caddy.
I bought another one this time from PC world, (A WD Blue). This lasted about 2 days. The drive is completely un accessible.
I have tried in a caddy, even placed it in a PC laptop and tried running format tools on it. The drive is not shown as being connected. (from the BIOS).
This is the 3rd drive the MacBook has wrecked. Any idea as to what is happening.
