Device Overview
(8) Drive-specific function (specification)
The disk drive measures the environment temperature. When the temperature
becomes about -20ºC or lower, some of the functions of internal drive operation
are automatically changed. The functions to be changed are listed below.
1) Receiving Write-related commands (writing data into user areas)
The disk drive disables the Write cache function, which is described at (7),
writes data into user areas, and automatically performs the data verify
operation (Read check) for those areas.
2) SMART operation
While the SMART function is enabled, a SMART attribute value or other data
may be written into the system area of the disk drive for periodic information
storage. When the temperature becomes lower than the specified value,
however, the data is only updated in the memory of the disk drive and not
written into the system area (temporarily suspended).
