Table 107 Set Max A ddress Ext Command (37h)
This command is immediately preceded by a Read Native Max Address Ext command.
This command overwrites the maximum number of Address of HDD in a range of actual device
capacity. Once device receives this command, all accesses beyond that Address are rejected with
setting ABORT bit in status register.
When the address requested is greater than 268,435,455, words (103:100) shall be modified to reflect
the requested value, but words (61:60) shall not modified. When the address requested is equal to or
less than 268,435,455, words (103:100) shall be modified to reflect the requested value, and words
(61:60) shall also be modified.
If this command is not supported, the maximum value to be set exceeds the capacity of the device, a
host protected area has been established by a Set Max Address command, the command is not
immediately preceded by a Read Native Max Address Ext command, or the device is in the Set Max
Locked or Set Max Frozen state, the device shall return command aborted.
The device returns the command aborted for a second non-volatile Set Max Address Ext command
until next power on.
Output Parameters To The Device
