Table 107 Set Max Address 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 Address 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 Address command is aborted.   

For more information, see “0   

commands” on Page 61.   

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 in 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.
