Hi,

I am getting chkdsk errors in read-mode frequently on Windows 2003 64 bit storage server with SP2 machine OS partition ( C drive). When I ran vrfdsk.exe to verify - it generates Application error in event logs. The C drive partition size is 165GB.

Error details :

Usually these errors are a result of "access denied" somewhere when loading the binary (the application error is indicative of a crash, and almost all of them involving ulib.dll involve crashing with the code 0xc0000005, access denied). I've seen this error many times, and always on Windows 2003 x64, and it was always a permissions issue. Running procmon.exe while attempting to run vrfydsk might show you where the access denied errors occur.
