Hi,

I was wondering if someone could assist as I have never seen this error before and could do with some assistance to help resolve it. I have brand new built Windows 7 Professional PC on RAID 1 using an LSI MegaRaid controller card. CHKDSK seems to pass detecting no issues on all volumes on the machine yet this error continues to appear, how can this be fixed?

Risk: High
Type: Error
Source: Ntfs
Category: 0
ID: 55
Date: 2014/4/11
Time: 11:0:41
Description:
The file system structure on the disk is corrupt and unusable. Please run the chkdsk utility on the volume \Device\HarddiskVolumeShadowCopy8.

Any assistance would be really appreciated.

Thanks

It looks like a corrupt VolumeShadow copy ... I assume you have System Recovery still enabled on the system?

You could try disabling it for a while and see if it helps, or make sure no other software is using VolumeShadow copies (e.g backup solutions).

Here's a how to to turn off system restore: http://windows.microsoft.com/en-ie/windows/turn-system-restore-on-off#1TC=windows-7

We use Shadow Protect for backups and that does use VSS. Is there any way to reset the VSS so any corruption can be reset?

Does the drive have a letter assigned to it?

Run chkdsk again without any switches.

Normally yes ...

You'll need to open a command with elevated rights (right-click run as administrator) and check if there are VSS:

vssadmin list shadows

If you just want to delete all VSS you can use wmic, also in elevated command window:

Firts type "wmic"

then type: "shadowcopy delete"

Another option is to keep using vssadmin to delete them... Something like this should work:

"vssadmin Delete Shadows /For=C: /All"

All the drives that have a drive letter assigned have had a chkdsk (drive letter) and no errors have been detected on them.

Would the following "vssadmin Delete Shadows /For=C: /All" delete all VSS copies and all it to re-create new ones which are not corrupt?

Will this affect the VSS writers which are used with Shadow Protect.

This will delete all shadows yes ... Leaving room to create new ones, which hopefully aren't corrupt anymore yes...

This would normally not affect the VSS writers no ...

You can also try to delete only the oldest onces

like so:

vssadmin Delete Shadows /For=C: /Oldest

or delete specific ones like so:

vssadmin Delete Shadows /shadow=long-shadow-id-number-here

I've seen this before on a brand new HP Pc that I took out of the box for a client and setup. It turned out the hard drive was going bad as we set it up on the first day.  Since they had just purchased it at Best Buy, the best solution was to take it right back and get another new Pc. the chances of having to bad drives are slim.

I set that one up and they never had a problem.

You might consider replacing that drive and restoring from a backup.

Hope this helps!

It's a RAID1 so no need to restore if it's just the one drive failing ... But could be a drive going bad, though ckdsk didn't find anything ... Not that this is always a given though.

CHKDSK did not find anything wrong nor does the RAID controller and they are both enterprise drives. I think it may just be a corrupt Shadowcopy due to something else so will try that first.

Thanks for the ideas though, really helps.

Hi,

I ran the command:

Firts type "wmic"

then type: "shadowcopy delete"

As the other one did not work. And also detected the following on the LSI MegaRAID event logs:

Sun, 13 Apr 2014 09:57:51 GMT Daylight Time:
[rr640l]: Device 'WDC WD1003FBYZ-010FB0-WD-WCAW36781107' at Controller1-Channel3 SMART test result: FAILED!


So I will be swapping this drive out as it could also be the cause of the problem in the background.

I will update the ticket further when all this has been completed so we can see if the issue has been fixed.

Hi folks, as outlined I replaced the drive in the RAID array. I am still getting these SMART errors though the RAID shows the array as normal so am uncertain if this is the second enterprise drive that is faulty or whether it could be the controller.

I am also getting these errors in the event log related to the Shadowcopies. I can create manual snapshots without an error:

The shadow copies of volume C: were aborted during detection.

Any ideas what could be going on? The PC does seem to hang randomly and I am uncertain exactly what is causing this at present.

What model is the raid card?

Is volume showdow copy set to automatic in services.msc

To open services.msc click start then type in run in search hit enter type in services.msc in run box.
Now scroll down to volume shadow copy set it to automatic startup the click on start button.click apply and ok then exit try again.

Maybe try disabling "System Protection" in system properties (if it's still enabled), it uses snapshots to, maybe it helps turning it off to see if the errors stop?

I see the following error:

While re-activating on \Device\HarddiskVolume4, VDIFF has detected that previous boot session ended with a crash. VDIFF is terminated.

The system hung again today and had to be cold re-booted. Basically it will randomly just stop responding to everything and I cannot determine what the cause is.

This person on EE had the same error.  His hardware was different, but the solution may help

•      Increase the Paging File to 4 times the Physical Memory on a partition that isn’t the   System partition.

Already have done that, it does not seemed to have made a difference. I do run ShadowProtect and think the issue could be there.

Have you contacted ShadowProtect with the issue? Since you are using their product, they would probably be the subject matter experts.

Well, I do think the issue is a mix between their product and other issues on the OS, VDIFF and Shadowcopies etc.

Ok, then I think I cave the correct suggestion... contact them and check on the error message.

Let me know what they say. I'm interested in finding out also.

I have ordered a new controller card which will be arriving on Friday and will be rebuilding the RAID. When we first installed the card two of the ports did not work and the other two did and we assumed everything would be ok, but clearly even after replacing what the controller card said was a faulty hard drive with another (both enterprise drives) it reported the same issue on the same channel.

I will update to let you know how the server is after the card has been changed and all rebuilt.

Hi all,

Just to conclude, the new RAID card was installed today with new enterprise hard drives throughout and the system is running perfectly at present with no glitches. I conclude the issue was with the RAID controller so will go ahead and close this case. Thanks for all that assisted.

Reason I have chosen my answer is because this was the end solution to the problem.
