Create mirror software raid with bad blocks hdd. How to check data integrity?
- by rumburak
There is error in System event log like this one: "The device, \Device\Harddisk1\DR1, has a bad block."
Because of above I created Raid 1 on this disk and other one. I'm using Windows Server 2008 R2 software RAID volumes.
Volume in Disk Manager is marked as "Failed Redundancy" and "At Risk". I could command to "Reactivate Disk" and it's starts to re-sync, but after a while it stops and returns to previous state. It stops re-sync on bad block on old disk and creates same error in System event log.
Old disk status is Errors, new disk status is Online.
How can I check that there is exact copy of the old disk on new one ? It is server machine so I would prefer to keep it running during this check.
