Notes.
[1] The Peripheral Qualifier field and Peripheral Device Type field value of 00h indicates a direct-access
device (magnetic disc) is connected to this logical unit.
[2] Page 80h provides the product serial number and product circuit board number for the drive.
[3] The Page Length field specifies the length in bytes of the product serial number page. Older products that
only support the Product Serial Number parameter will have a page length of 08h, while newer products
that support both parameters will have a page length of 14h. If the allocation length is too small to transfer
all of the page, the page length shall not be adjusted to reflect the truncation.
[4] The Product Serial Number field contains ASCII data. The least significant ASCII character of the serial
number shall appear as the last byte of this field. If the product serial number is not available, the drive
returns ASCII spaces (20h) in this field.
[5] The Board Serial Number field contains ASCII data that is vendor specific. The least significant ASCII
character of the serial number shall appear as the last byte of this field. If the board serial number is not
available, the target shall return ASCII spaces (20h) in this field.
