Disk Status

Click on the tabbed menu on the desktop to enter the Disk Status window. The first 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 configuration 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 flying 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.
