How do I access an HDD previously in a MyBook Pro?!

Hi all

I have a MyBook Pro and an HDD which was in the MyBook Pro but is now not in it - it was removed due to reaching capacity and a new drive added into the MyBook Pro. It was a standard drive, not mirrored or cloned.

I now need to access the data on the old HDD.

It doesn’t get picked up in the MyBook for some reason and when I put it into a dock drive reader it doesn’t show up either.

I’m concerned the data is now no longer accessible for some reason!

Can someone help me work out a way to access this drive please?!

Thanks
Geoff

Disk removed from My Book Pro are RAID protective and can’d be access on connecting directly with computer or docking device. Data can be accessed on connecting it with the same My Book Pro enclosure.
