Looks like a storage issue. You may want to run whatever hardware diagnostics are provided by the storage/server vendor.

also check firewall rules or AV settings, depending on how you're getting your storage, i.e. iSCSI can break your connection.SF - MCITP:EMA, MCTS: MOSS 2007, OCS 2007, Exchange 2007 -- http://www.scottfeltmann.com

Yes, this is a storage error. Please check your store hardware and let us know the result. Thanks,Elvis
