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.
