Table  106 Set Max A ddress Command  (F9h)   
The Set Max Address command overwrites the max LBA/CYL of HDD in a range of actual device 
capacities. The device receives this command, all accesses beyond that LBA/CYL are rejected with 
setting ABORT bit in status register. Identify device command and Identify device DMA command 
returns the LBA/CYL which is set via this command as a default value.   
This command implement SET Max security extension commands as subcommands. But regardless 
of Feature register value, the case this command is immediately preceded by a Read Native Max 
Address command, it is interpreted as a Set Max A ddress command.   
The Read  Native Max Address command should be issued and completed immediately prior to 
issuing Set Max Address command. Otherwise this command is interpreted as a Set Max security 
extension command which is  destinated by feature register. If Set Max security mode  is in the 
Locked or Frozen, the Set Max A ddress command is aborted.  
For more information, see “12.10.2  Set Max security extension commands ” on Page 66.   
In CHS mode, LBA High, LBA Mid specify the max cylinder number. The Head number of Device 
and LBA Low are ignored. The default value(See default CHS i n Identify device information) is used 
for that.   
In LBA mode, the Head number of Device, LBA High, LBA Mid and LBA Low specify the max LBA. 
This command sets this LBA as the max LBA of the device.   
After a successful command completion, Identify Device response words (61:60) shall reflect the 
maximum address set with this command.   
If the 48-bit Address feature set is supported, the value placed in Identify Device response words 
(103:100) shall be the same as the value placed in words (61:60). However, if  the device contains 
greater than 268,435,455 sectors, the capacity addressable with 28-bit commands, and the address 
requested is 268,435,455, the max address shall be changed to the native maximum address, the 
value placed in words (61:60) shall be 268,435,455 and the value placed in words (103:100) shall be 
the native maximum address.   
If a host protected area has been established by a Set Max Address Ext command, the device shall 
return command aborted.
