Hash mismatch

Does anybody know how to fix this problem? It is related to a Windows 8 64-bit platform and seems to be rather common (see Web results for "Amd64\CNBJ2530.DPB" of prncacla.inf*"*).

No apparent malfunctions, but very slow startup, especially the first one at morning.

Below what appears in the CBS.log after multiple sfc /scannow(s) that say it is impossible to repair some damaged files.

I have tried to fix by uninstalling  and re-installing KB2769165, with no result. Any other ideas?

I found something very interesting here:

http://social.technet.microsoft.com/Forums/en-US/w8itprogeneral/thread/26f35def-6f55-4c07-9ba8-73e2d402e6cc

I am going to try the dism /online /cleanup-image /checkhealth command and see how it goes.

L.E. Actually, there are 2 commands to run:

dism /online /cleanup-image /checkhealth

dism /online /cleanup-image /restorehealth

I will be back with the results.

Very Late Edit:

There is also a tool I found recently that helped me solve this issue in Windows Server 2012 R2.

The above commands didn't work so I ran this tools and it solved the problem. You can download the tool here:

I have been checking this issue through other Microsoft Communities (England, France, Italy). According to many experts the problem is not significant. Moreover, looks like sfc often reports false errors. Both my PCs (1 laptop Windows 8 Pro 64-bit and 1 desktop Windows 8 32-bit with Media Center) report the same "hash mismatch" but don't seem to show any malfunction. No Canon printers installed! I hope that Microsoft will solve this mystery ... sooner or later.

    I just had this same error on a Windows 2012 R2 server.

    I run regular sfc checks on servers just to make sure everything is ok and this error came up last week.

    sfc /scannow

    was unable to fix the issue and

    dism /online /cleanup-image /restorehealth

    ended in another error, saying that it cannot fix the corruption.

    So I searched and found a nice little program that solved the issue with one scan. It is called sfcfix and can be downloaded from here:

    http://thetechcookbook.com/automatic-sfc-corruption-repair-sfcfix-exe/

    just to be safe, before using it, scan the exe online:

    I ran the System File Checker tool because I kept on getting an error code when I was trying to start syncing a library in OneDrive for Business.  I was told to run the SFC and I did, and I got the message back that some files couldn't be fixed.  I searched in the CBS.LOG file and got the following files that couldn't be fixed.

    2015-09-22 00:04:01, Info                  CSI    000005b0 [SR] Cannot repair member file [l:36{18}]"Amd64\CNBJ2530.DPB" of prncacla.inf, Version = 6.3.9600.17415, pA = PROCESSOR_ARCHITECTURE_AMD64 (9), Culture neutral, VersionScope = 1 nonSxS, PublicKeyToken = {l:8 b:31bf3856ad364e35}, Type = [l:24{12}]"driverUpdate", TypeName neutral, PublicKey neutral in the store, hash mismatch

    Notice that they are all CNBJ2530.DPB files, all in the Windows/WinSxS/AMD64_pmcacla.inf...etc... folders (though in different final folders.  When I search for that file I find three copies of it in three different folders, two being of 1,900 KB in size and one being 1 KB in size.  How do you tell which one(s) are not right?  Should I just go to my laptop that has the same version of Windows 8.1 on it and copy those files into their respective folders on my (damaged, apparently) desktop?

    Thanks!  I'd really like to get my OneDrive for Business syncing my files again!
