Hi,

 

attached to my WinXP SP3 machine (using NTFS), my Toshiba Canvio external HD (G:) recently became inaccessable, and I used Piriform's Recuva to successfully recover my data, approximately 190GB. I recovered to a brand new WD Passport 1TB external drive, labeled F: with 963GB of free space.

 

Now when checking properties of the F: drive, it indicates 658 GB are in use. Inside the Recuva results window, I see the file $Badclus is 466GB in size. From the file info tab:

 

Filename: $BadClus
Path: G:\

Size: 466 GB (500,105,760,768)

State: Not deleted

Creation time: 7/27/2010 03:56

Last modification time: 7/27/2010 03:56

Last access time: 7/27/2010 03:56

Comment: No overwritten clusters detected.

Data streams: 2
$BadClus
$BadClus:$Bad

 

 

My original goal was to simply save the entire drive before it fails. But after some research I think I may have copied the MFT and bad sector info to the new drive?  I did tell Recuva to recover the entire drive by checking G: in the file tree, rather than pick and choose files to recover.

 

So has 466GB of new drive been marked as bad? Can I get chkdsk or a third party software to recheck the disk and straighten this out?  This is new territory for me, I am somewhat confused and not sure of the risks to my data. I couldn't find an exact solution on the web.

 

Thank you for any guidance you can supply.

I would run chkdsk on that failing drive and see if its able to repair the files. Chkdsk "driveletter" /f should do the trick.

chkdsk would not run on the failing Toshiba drive, giving the error message "unable to determine volume version and state, chkdsk aborted".  So I went ahead and retrieved my data, and then I'll troubleshoot or reformat.  Now the new drive has this $badclus business, and I've managed to stump the internet looking for answers. I ran chkdsk /f /r on the new drive but it still indicates 650+GB being used.

One possibility would be to copy out your recovered data then run a full format, not a quick one, on the drive. That should cause the $Badclus file to be rebuilt.
