Server 2003 HP DL380 G5, DC P400 raid disk corruption

Hi,

I have a HP DL380 G5, running server 2003 R2 Domain Controller running on a p400 Raid. The server is up for replacement next year but I am currently having to run disk checks on it every 2 weeks to fix the corruption on the disk as the backup will not run (StorageCraft).

I have replaced both harddrive in the RAID but this did not fix the issue. It only affects the D: drive partition which holds the My Docs folder redirects and the company shared data. It does not seem to affect the server in any way but requires a check disk to resolve the backups.

The Error
The file system structure on the disk is corrupt and unusable. Please run the chkdsk utility on the volume Data.

The raid driver is up to date.

I do not know if this is a coincidence of not but we did start using EFS encyrption on the folder redirects about the same time as this issues started.

Any thought would be much appreciated

Many Thanks

Baz

For sure it is not a physical issue.
Would it be possible for you to get a new partition and copy the D: drive to this new partition ?
Then format D: then copy data back on it ?

The backup cannot read the data because of the encryption and thinks the file system is corrupt. This could be your issue. To check this simply disable the encryption and see what happens.

I do not think this is the issue as when I do a read only check disk it fails. An backups are done at the bit level so they are not concerned with encryption

Connect further...control easier

But you said yourself it started doing this after starting using encryption.

The backup works fine until the corruption occurs, then if I run a read only check disk it fails so I run a full check disk and the issue is resolved and the backups continue to works until the corruption happens again, so I don't think it is due to the backups not being able to read the encrypted files as most of the time the backups work fine . I was just wondering if EFS encryption on a disk would make in more likely to become corrupted as it started to happen around the time encryption was added.

Stampel: I will give your suggestion a go.

Ok. The corruption usually happens if someone manipulates the files on the share. It is like keeping them open and shutting down the PC without saving the file and closing it first. Many read/write operations (create file/delete file) make the drive dirty as well.
If you cannot control the data usage on user side then maybe you need to setup some task in schedule which would randomly check the file system.
