working conditions. The Rapid 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 of the read/write head elements. Mechanical test
includes seeking and servo on data tracks. Scans small parts of the drive's surface (area
is vendor-specific and there is a time limit on the test). The test checks the list of Pending

Note that a Complete test will scan through the HDD's disk sectors and will take a long
time to complete. A Complete test will take around 3 hours on a 1TB HDD.
