Notes.
[1] The Peripheral Qualifier field and the Peripheral Device Type field are as defined previously. (see Table
5.1.1-8 notes).
[2] Page C1h provides the date code from the disc drive defect list (see Table 5.1.1-10g).
[3] The Page Length field specifies the length of the product date code. 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 Date Code field contains BCD data. The least significant hex character of the date code shall appear
as the last byte of a successful data transfer.
Date is represented by 4 binary bits per date digit (0-9 hex), giving 6 hex digits for a date of the form
mmddyy. Add 30h to each hex digit to create a date in ASCII form (30-39 in ASCII is 0-9 decimal).
