The application event on our mailbox server is giving the error :
At '9/28/2016 8:17:53 AM', database copy 'XXXXXXXX' on this server encountered an error. For more information, consult the Event log for "ExchangeStoreDb" or "MSExchangeRepl" events.
At '9/28/2016 8:17:51 AM' database copy 'XXXXXXXXX' on this server appears to have an I/O error that it may be able to repair. To help identify the failure, consult the Event log on the server for other storage and "ExchangeStoreDb" events. Service recovery was attempted by failover to another copy. The failover was unsuccessful in restoring the service because of the following error: 'There is only one copy of this mailbox database (XXXXXXXX). Automatic recovery is not available
In the system events the error is:
The device, \Device\Harddisk4\DR4, has a bad block.
disk 4 is hard drive on which the above database is located.
What should i do? Should i run a chkdsk on disk 4. The used capacity is 1.1 TB. Only two databases are giving error on the disk which has 5 databases. I am moving the mailboxes from the databases to a different hard disk. What is the best solution? Thanks.
