Cannot Mount Disk: Corrupted TM Partition

[msoon77]

Hi people.

Hope you can help me out here, I don't know what else to do about my external WD drive that will not mount.

It suddenly happened today as I unplugged the HD by accident while TM was doing an auto backup.

It's a 2 TB drive that has been partitioned into 2 - one for normal storage and 1 for TM.

I've gone into Disk Utility and done a verify on the main volume and it says everything is okay. The TM volume is greyed out.

I've tried to do a repair on the TM volume and it just says:

- checking file system
- Volume repair complete
- "Updating boot support partitions for the volume as required"
= then it just gets stuck on this step indefinitely (i gave up on it eventually and force closed DU)

- I have tried to erase the TM partition but Disk utility won't let me.

The disk will not mount and will not show up on Finder for me to copy off my data elsewhere - I desperately need to save all my photos.

Here's a screenshot:

Can someone please help me or tell me how I can go in and somehow grab my files from the drive?

Thanks,

Mark
