An I/O operation failed for both the primary and the redundant copy of the data. It is unlikely that bad spots have appeared at the same offset on both disks.
Make sure the drives are on-line and are functioning properly. Check for Eventlog entries close to this one that indicate a hardware problem with one or both drives.
