My Book Essential 1TB - Cant Access

Drive was working perfectly until the power was unplugged.  Finder shows the Smartware software, but not the “my book” drive & files.

The smartware software says that the drive is unlocked, the light on the unit is illuminated, I have never set up a password for it.

Have plugged it into a windows machine with the exact same result.

I have been using this drive for my time machine backup and photo storage.

When viewing the drive in disk utility, it recognises it as a 1tb, but suggests it needs repairing, but the disk utility cannot repair it.

How can I get access to my files???

It it was still writing when it got unplugged it probably corrupted something. You can check this post  or this one
