The Set-Max-Address command must be immediately preceded by a successful execution of a Read-
Native-Max-Address command. Otherwise the Set-Max-Address command will be interpreted as
another Set-Max command or aborted as an invalid command.

Bits (3:0)
1: The maximum address value is an LBA value.
0: The maximum address value is a CHS value.
The selected device.
The native max address head number
(Identify-Device word 3 minus one) or LBA bits (27:24) value to be set.
Cyl High Contains the maximum cylinder high or LBA bits (23:16) value to be set
Cyl Low
Contains the maximum cylinder low or LBA bits (15:8) value to be set
Sec Num
Contains the native max address sector number (Identify-Device word 6) or
LBA bits (7:0) value to be set
Sec Cnt

Value Volatile
1: The device preserves the maximum values over Power-on or hardware reset.
0: The device reverts to the most recent non-volatile maximum address value
setting over Power-on or hardware reset.
After successful command completion, all Read and Write access attempts to addresses greater than
specified by the successful Set-Max-Address command is rejected with an IDNF error. Identify-Device
response words 1, 54, 57, 58, 60, and 61 reflect the maximum address set with this command.
Hosts should not issue more than one non-volatile Set-Max-Address command after a Power-on or hardware reset.
Devices should report an IDNF error upon receiving a second non-volatile Set-Max-Address command after a
Power-on or hardware reset.
The contents of Identify-Device words and the max address will not be changed if a Set-Max-Address command
fails.
After a successful Set-Max-Address command using a new maximum cylinder number value the content of all
Identify-Device words must comply with the following:
1. The content of words 3, 6, 55, and 56 are unchanged
2. The content of word 1 will equal (the new Set-Max cylinder number + 1) or 16,383, whichever is less
3. The content of words (61:60) equals [(the new content of word 1 as determined by the successful Set-Max-
Address command) * (the content of word 3) * (the content of word 6)]
