I have a My Book Essential 1.5 TB external drive, which I can no longer detect on my MacBook Pro.
I wanted to share some photos with my sister who also has a MacBook Pro and so I used the Mac Network setting to share the WD drive wirelessly. It was taking a long time to read and copy the files so we decided to just plug in directly to her PC. Straight off it said something like “can’t initialize” the drive. So I unplugged it an put it back into mine. To my shock I got the same error after putting it back into my Mac.
When I use DIsk Utility nothing appears for the external drive, on either Mac.
I just get a flashing locked button down the bottom.
She is running Snowleopard OS and I’m running Mac OS X 10.5.8
Any assistance would be greatly appreciated.
