Windows 7: chkdsk - "An unspecified error occurred <6672732e637878>"

22 Apr 2012   #1

Windows 7 Home Premium SP1-U 64bit
chkdsk - "An unspecified error occurred <6672732e637878>"

I started a chkdsk on a Win7 64bit computer that got stuck at startup repair. Before that though, I was looking around, the damage seems to be the windows files got messed up after an update. My computer data was intact when I looked around booted through a recovery cd and I checked again via a ubuntu live cd. My question is that the chkdsk d: /f apparently stopped in the middle and gave the following message:

An unspecified error occurred <6672732e637878>
Failed to transfer logged messages to the event log with status 50

What does that mean? Is it terrible? I just restarted the chkdsk anyway and as of now, it is finding less unreadable segments, but is there a risk of data loss?

Windows 7 Home Premium SP1-U 64bit

Also before this, I attempted to sfc /scannow /offbootdir=c:\ /offwindir=d:\windows and sfc /scannow when the first command didn't work. I also tried following the instructions here (Startup Repair Infinite Loop Recovery) but the numbers were off in SAM and one other one, Default I think.

If the chkdsk doesn't work, would the only option be a clean sweep? and is there a way that I can get a list of programs that I have saved on my computer (like how I could retrieve documents from Copy & Paste - in Windows Recovery Console

Edit: Looking some more in the forums, my list of actions most closely resemble the advice of this thread SFC error - Windows Resource Protection could not perform...

Windows 7 professional 32bit

Have you figured it out that how can it be rectified?
I am facing the same problem on my external WD Hard disk (931 GB) (it got corrupted while creating Windows Backup).
CHKDSK fails while scanning unindexed files for reconnecting them to their original directory.
I have tried chkdsk /f d: and chkdsk /r /f d: but both fail at this point.

Please help.

7,8,etc (all x64)
run as admin

Run cmd where you start chkdsk as admin. The error () is a failure to write to system log due to lack of privileges.
