Dying Server Hard Drive

Hi There,

Bit of a big issue currently going on,
Recently my server running Windows 2012R2 had a power issue which caused the redundant
Server to kick in.

After we fixed the primary domain server and got it back up and running, we checked our redundant server and the logs and found that
We had issues on one of the drives that stores the VSS.

We need to fix the corrupted disk before the end of next week,
We've asked the users to store that data on the cloud for extra security.

Could anyone please advise?

Kind Regards
Dominic

I would never "fix" a server drive.  You need to replace the failing drive immediately.

The cost of drives is so low there is no reason or excuse to not replace a suspect drive under any circumstance.

And if you are not running with some kind of RAID on a server you are just asking for trouble.

The drive is in RAID 1, only problem is i'm not sure how which one of the hard drives is the faulty on in the server? Ill buy a replacement drive for immediate delivery to fix the issue.

Use the management interface on the server to find out. On HP servers it's called iLO.

Or look at the server. The faulty drive caddy should have a red led on it.

Hi Dan,

The disks all have green lights,
We know the disk is failing because of event logging warnings.

Should I run an 'error checking' check in the properties windows on the D drive?

What is the make/model of the server?

That will tell us how to guide you better.

As Dan said, the management conco.e for the areay should tell you which one is suspect.

What are you seeing in the event logs?

Those messages do NOT indicate a hardware failure.  It is filesystem corruption.  Treat this exactly like you would address a non-RAID configuration that shows filesystem corruption.

(There are no entries for disk I/O errors like unrecoverable reads on block #xxxx)

I ran SFC /Scannow and the message I received back was 'Windows resource protection did not find ant integrity violations' ?

You misunderstand, it is not a problem with the hardware or the filesystem.  The data file itself is corrupted in context that whatever application use it, the file has incorrect (not unreadable) data in it.

The fix would be more like running a datafile validation program that the vendor who created that software uses to rebuild index files.   Look at the text of the messages, it tells you file name and what it doesn't like.

Contact the vendor (Dropbox) who wrote that software or read in the manual how to address the situation.

The error message is relating to inconsistent / corrupted file for an application.  If this was a problem with the hard drive then a windows log entry would have been recorded with unrecoverable read error on sector xxx.  As such, the solution is going to revolve around getting with the application vendor and determining how to recover/replace/repair the busted file.
