When CTPurge™ is completed, the drive will return ready status but will no longer be able to
process any new ATA commands as all internal rmware has been erased.
7.2.3. Status Reporting
The time required to perform a CTPurge™ operation depends on the capacity of the drive and
the type of purge operation that is being performed. The host should ensure that power to the
card/drive is maintained for the entire duration during the purge process. The following table
lists some typical numbers that can be expected.
The power consumption during a CTPurge™ operation is also dependent on drive capacity, the
type of purge operation requested and, to a lesser extent, the particular overwrite pattern used.
Some typical numbers are shown below:

CTWPROT™
7.3.
CTWPROT™ enables write protect function on the entire Cactus Technologies drive. This feature can
be activated in hardware or software. Hardware activation is by a mechanical write protect jumper.
The write protect function is sampled once during power on and cannot be toggled during device
operation. When the write protect function is activated, all subsequent Write commands that attempt
to store data to the ash memory will be accepted but silently rejected by the device; no Error status
will be returned to the host.
