7. 8 Disk Statistics
The page shows information on the disks in the
system.
Each disk displays its Reads, Writes, Others, Transfer
Retries, and Media Retries. If a disk is generating
errors, it may fail sometime in the future. RAID 5
configurations should distribute reads and writes
evenly among all of the drives.
Available Information:
