Hi, I have just bought myself a SSD for my Macbook Pro mid 2012 running El Capitan and decided to buy a caddy for my old SSHD to use as an external drive. I plug the external drive in and in disk utility go to the drive to try and format it but I just get the message 'Erase Process Failed'. The SSHD is 500gb with 150 gb as a windows partition, is it possible to format the drive?
 
Can you try with the command line?

Get the disk number of the connected drive:
Code:
diskutil list

Reformat the drive:
Code:
diskutil eraseDisk JHFS+ MyDisk disk2

Maybe that can give more information for the failure.

Hi Boast,

Apologies I was a bit quick to post. The drive was 500gb with 150gb partitioned as windows. I was trying to format the whole drive but found if I just selected the OS X partition and erased it would let me and then I could select the whole disk and erase it.

Thanks for the reply.
