CHKDSK showing same error even after fixing (Windows 7 SP1)

I have a 6TB data hard drive (SATA mechanical) on my Windows 7 SP1 (64-bit) computer. It isn’t my boot drive. I just use it to store data files.

This morning my computer froze and showed blue screen of death (I was testing experimental software). It then rebooted.

After the reboot, I let it settle down then did the usual CHKDSK on all drives.

CHKDSK D: showed this result:

C:Windowssystem32>chkdsk d:

So I promptly ran CHKDSK D: /F /V to fix the problem. The results are shown below.

So CHKDSK reports that the problem is now fixed. So I run CHKDSK D: again to make sure and it reports exactly the same problem as if nothing has been fixed.

I have tried this loop 4 times now – I run CHKDSK D: and it reports problems. So I run CHKDSK /F /V and it says problems are fixed. But when I run CHKDSK D: again, it reports the same problems it did originally. And into a loop it goes.

I am running CHKDSK from an elevated command prompt. I have also tried it from Safe Mode and got identical results. I have rebooted several times and same results.

Note that the first time I ran CHKDSK /F /V, it said it cleaned up around 167 unused index entries. However, every time I have run it since, it always reports that it cleaned up 1 unused index entry. So clearly, it was able to fix all but one of the unused index entry errors but is unable to fix just one of them.

So I have 3 questions:

• Am I able to fix the problem I have here?
• CHKDSK D: /F /V is showing the ‘Cleaning up…’ lines after the
  ‘Security descriptors’ bit. Does this mean the error is in the
  security descriptors and if so, is that serious and should I be
  worried about it?
• I am due to replace the hard drive in about a month. If I copy all
  the files over using a straight-forward Windows Explorer copy and
  paste, then the problem with the unused index entry should not copy
  over to the new drive, is this correct? If the files copy over, then
  I can just assume that they must be intact and running CHKDSK on the
  new drive shouldn’t report any unused index entries after the copy.
  Is this correct?

CHKDSK does not create a FOUND folder and does not seem to store any .chk files. It does not report any other errors other than ‘Cleaning up unused index entry. So I don’t know but to me it doesn’t sound like any files are missing or corrupt.

Many thanks.
