Cannot Recognize Drive / Deleted Partition Mapping?

[PaThKu]

So, I was moving partitions in VolumeWorks and accidentally ejected the Lacie Disk. Now whenever I try to use it i get this:

I clicked initialize once, but I closed DiskUtility and it never had time to do anything. I know this because I can still use DataRescue to get my files. The problem is, the files will not be named or organized correctly! On diskutility, it will NOT let me mount the the drive (although it still shows the icon on disk util) so I cannot repair it. Please help!

Edit:
Shoot, apparently initializing it removes the partition map :O. How can I get the partition structure back in place?

When the partition structure is gone, it is gone.
If DataRescue still finds some files, backup them and then wipe the partition clean after it.

I have had the exact same thing happen to me recenlty. I was wondering if you had any success getting the file back from your drive with the datarecovery software?

Or did you have to do somehting else?
