A Disk Read Error Has Occured (RAID 5)

Hi guys,

Wondering if you can give me any tips or ideas on how to solve the following issue.

I have an SBS 2008 server SP2 that is running in RAID 5, if i recall correctly its a Dell T110.

One day the customer came in and the error on the screen read "A disk read error occured Press Ctrl+Alt+Del to Restart".

I arrived onsite, checked the RAID controller (Perc 6i) the controller and all the drives are marked as optimal so it isn't a failed drive. I then out of curiosity used Hirens Boot CD and selected boot to my PC and what do you know the server booted up correctly.

I had opened a call with Dell and ran their Dset Diagnostics which found there to be no issue with the controller, drivers or a RAID puncture.

So i am wondering where i can go with it no being a hardware issue but with the system not telling me it is missing a specific file, i have ran sfc/scannow within the environment and it finished without an issue. I did boot to the system CD earlier on and viewed that it could see the partition and was thinking maybe a bootrec /fixmbr might help but i havn't run it yet.

Any idea's or pointers on how to proceed, any advice is appreciated. Hoping someone has seen this before as normally to me a disk read error is generally a failed hard drive.

Thank You

Alex
