utility then polls the hard drives for statuses of the key attributes of its working conditions. The

Quick test checks the electrical and mechanical performance as well as the read performance

of the disk. Electrical tests might include a test of buffer RAM, a read/write circuitry test, or a test

Scans small parts of the drive's surface (area is vendor-specic and there is a time limit on the

test). The test checks the list of Pending sectors that may have read errors.
