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.

Wow. That's just nasty... this is by no means an answer, but I think you may have to end up biting the bullet on this one and just repartitioning the entire drive. Any other thoughts? – UtahJarhead Oct 7 '12 at 20:30
    
I think I will have to.. I just thought Id ask here beforehand - I have almost 1.5TB of data on there :( fortunately I don't have any important documents or photos.. – volting Oct 7 '12 at 20:43
    
Give this topic a day or two and wait to see if any positive answers show up. – UtahJarhead Oct 7 '12 at 20:58
    
@volting - with minitool partition magic, did you try / can you assign a drive letter to the partition? – Carl B Oct 7 '12 at 21:07
    
@UtahJarhead - Thanks, Was planning to... :) – volting Oct 7 '12 at 21:41

As you have indicated that you have installed Minitool partition wizard , let's use it.

With Minitool partition wizard open:

  • Right click the drive volume that is unallocated
  • Select Create from the options listcreate
  • you will get a pop up box like this, (Name the volume if you like)click OK

create2

  • you will see an operation pending to create at the bottom. click the Apply check mark to executecreate 3

  • Right click on the newly created volume and select Check File System

    create4

  • When box pops up, select Check & Fix detected errors and click Start.create5

Good answer - but there was no need to go to so much trouble :)- I just thought that creating a new partition would wipe whats already there - but at this point I don't think It matters.. Ill give it a shot! – volting Oct 7 '12 at 22:23
    
Great now I have one big partition with NO DATA! – volting Oct 7 '12 at 22:27
    
LOL - No reply eh! Sorry got to downvote this as it is not a solution. -Maybe I didn't make it clear that I want'd to save my data.. but I thought that would be a given. – volting Oct 8 '12 at 7:06
    
@volting - My appologies. You had noted in your comments that there was nothing important like pictures or docs. – Carl B Oct 8 '12 at 14:31
    
@volting - you can use data recovery from the same minitool company to recover data. free edition link. powerdatarecovery.com/download.html – Carl B Oct 8 '12 at 14:40
