Storage\Disk Media Errors Disk Media Errors is the count of errors encountered by the disk
controller when accessing disk blocks on the physical disk.
Often the controller can access the disk block with a specific
retry policy. When a disk block cannot be accessed via the retry
policy the controller reassigns the block.
In either case, disk errors are indicative of disk IO latencies, and
an increasing number could potentially indicate disk
replacement. Typically this should be a zero value.
Note that a single “bad block” being repeatedly accessed could
cause this value to increase, so there is no definite rule that
guarantees that a certain number of errors occurring within a
specific time interval would warrant a disk replacement. This is
simply provided to view the error occurrence pattern for a
physical disk so it could related to other system behaviors.
