Corrupted NTFS Drive showing multiple unallocated partitions

My external hdd with a single NTFS partition was accidentaly plugged out (kids!)... and is now corrupted.

Iv tried running ntfsfix - with no luck - output below..

When I look at the disk under disk management in Windows 7 it shows up as having 5 partitions 2 of which are unallocated - none have drive letters and it is not possible to set any (that option and most others are greyed out) - so I can't run chkdsk /f

Iv tried using Minitool partition wizard which was mentioned as a solution to another similar question here. It showed the whole drive as one partition, but as unallocated, and the option -- "Check File System" was greyout.

Is there anything else I could try ?

    This doesn't look like a partition table
    Probably you selected the wrong device.
