Disk Status
Click on the tabbed menu on the desktop to enter the Disk Status window. The rst information
is the Logical volume working status.
The second window displays the working status of individual disk drives, including model
name, capacity, S.M.A.R.T., state, and temperature. Note that if a hard drive is stated as
an ArrayMember, the physical drive has already been included into a logical, multi-drive
conguration such as RAID0 or RAID1.
Click the tabbed menu below to see more information such as the current working status
reported through SMART.
S.M.A.R.T. is short for Self-Monitoring, Analysis, and Reporting Technology. S.M.A.R.T. provides
near-term failure prediction that monitors predetermined disk drive attributes that are susceptible
to degradation over time. Predictions are limited to the attributes implemented by the HDD
manufacturers.
Although attributes are drive specific, a variety of typical characteristics can be identified, for
example:
Head ying height, Data throughput performance, Spin-up time, re-allocated sector count, seek
error rate, seek time, spin try recount, and drive calibration retry count, etc.
