So I’ve had my 2TB My Book Essential for about 2 years and it’s only ever worked on my macbook pro. I tried plugging into my PC running windows 8, and it made the sound that indicated it recognized something despite no drive popping up. I tried assigning a letter drive to it but that didn’t seem to work.
After doing that, the external hard drive doesn’t work on my macbook pro either. I get this error now - “This disk doesn’t contain an EFI system partition. If you want to start up your computer with this disk or include it in a RAID set, back up your data and partition this disk.”
I have 2 years worth of files on this and I can’t access it on either my PC or my macbook… is there anyway of getting this to work on either computer??
