Q: Error: "CHKDSK cannot continue in read-only mode" and "An unspecified error occured (766f6c756d652e63 3f1)"

I'm trying to run a CHKDSK on my hard drives. Everytime I try to do "chkdsk C:" or any other volumes (internal or external) elevated command prompt. I got

"This type of file system is NTFS.
Errors found. CHKDSK cannot continue in read-only mode."
(This is all I get, nothing inbetween)

I have three internal volumes C: D; and E:. Run chkdsk on any volume returns "CHKDSK cannot continue in read-only mode". Run with /f on C: will check the disk (no error) in reboot. Run /f on any other volume, I got "An unspecified error occured (766f6c756d652e63 3f1)".
Got same error in recovery mode, safe mode, using administrator account or UAC disabled.
Also got same error when trying chkdsk on any external hard drives.
I formated my E: and ran chkdsk on empty volume, Got the same error.

Defragment runs OK without any problem. External hard drives can be checked (no error and bad sector) on another computer (win7 pro x64).
My external hard drives can be ejected without any problem. But ejection always fail after running "chkdsk /f".

This computer is win7 pro x86.
Installed Software: VMWare workstation 7, Microsoft Security Essentials, Visual C# 2010 express, Office 2003, Daemon Tools. DropBox

Please help me solve the puzzle.




After some debugging, I found the ifsutil.dll reported a "divided by zero" exception.
Finally I found there's a Microsoft hotfix for my netbook CPU (AMD C60).
A Chkdsk command fails with an unspecified error on a Windows 7-based or Windows Server 2008 R2-based computer that uses a low frequency AMD CPU
This hotfix solved my problem.

Did this solve your problem?

Sorry this didn't help.
