HDD is recognized but not the partition - format required

[johni]

Hello,

I've been filling a My Book Essential 1TB drive with a lot of stuff the past years.
Last year it wasn't active at all, and yesterday, when I tried to plug it the partition was not recognized although the drive was.
I was asked by OSX to format the partition in order to make it useable again.

I haven't done it yet, I wanted to ask you if there's any chance of retrieving the data stored in that drive over the past years?

Thanks

you need Kernel Recovery software and search partion and show your data
