Command (7)
Command (7)
The Read-Long-Sector command performs similarly to the Read-Sector(s) command except that it
returns 516 Bytes of data instead of 512 Bytes. During a Read-Long-Sector command, the ATA Flash
Disk Controller does not check the ECC bytes to determine if there has been a data error. Only single-
sector Read-Long-Sector operations are supported. The transfer consists of 512 Bytes of data
transferred in Word-Mode followed by 4 Bytes of ECC data transferred in Byte-Mode. This command
has the same protocol as the Read-Sector(s) command. Use of this command is not recommended.
This command returns the native maximum address. The native maximum address is the highest
address accepted by the device in the factory default condition. The native maximum address is the
maximum address that is valid when using the Set-Max-Address command.
The Read-Native-Max-Address command output will take the following format:
