MyBook Essentials 1 TB mac Drinve not working in Lion

My WDHIU100000A-00  Drive has not worked since Lion upgrade.  It Hangs my computer on startup unless it is unplugged.  i cant seem to find a way to access the drive and update it so it works.  I use this as a photo backup so id like to try to not have to reformat it.  has anyone else been able to solve the issue with this drive??  Appreciate any help


I don’t know but it sounds like it’s the Lion upgrade. It maybe a driver issue did you check WD site and see if there are any updates for it? Lion has had some compatibility issues.
