Hello everyone,

I have a SBS2011 Server up and running.
It boots from a RAID 1. (The RAID crashed a year ago and was repaired, if further information about that is needed, i might be able to provide it)

Since a few days, the Server-Backup fails and in the event-logs i see, there are I/O Device Errors for Partition C.
A partitioning tool tells me, that drive c has bad geometry and in detail, that the boundaries of partiton c exceed their container.
In Windows Storage Management Console a right-click on C -> shrink volume only gives me a message, that this operation couldn't be done due to an I/O Device-Error (but not for another partition on the same physical drive, so i think it might not be hardware failure)
The RAID Mangement Console tells me the RAID is in optimal state.

Partiton C contains the system, the start-partiton and is active. ( I think before the crash a year ago, the start-partition was on a 100MB system-reserved partition)

The server is up and running and a productive system, I can only reboot it on the weekend or at night.

Maybe someone can help me find out what is going wrong, thank you!

Best regards Roy
