Command Specifications

c.Page descriptor

The "Page Descriptor" consists of a two-byte page header (or four-byte page header when using subpage format) followed by a parameter field. It is classified based on the parameter function attribute into units called "Pages." The individual "Page descriptors" in the MODE SELECT and MODE SELECT EXTENDED commands may be specified independently by the INIT and multiple "Page descriptors" may be specified continuously in the desired sequence.

−Page code

This field specifies a code (Page No.) that indicates the type of "Page descriptor."

−SPF (Sub Page Format)

When this bit is set to "0," this indicates that the Page_0 Format (Short Page Format) is being used, and when this bit is set to "1," this indicates that the Sub_Page Format (Long Page Format) is being used.

If "1" is specified for a page that does not support the Sub_Page Format (pages other than Page 19 and Page 1C), the MODE SELECT command is terminated with the CHECK CONDITION status (ILLEGAL REQUEST [= 5]/Invalid Field in Parameter List [= 26/00]) and all the parameters specified with the command are invalidated.

−Page length

This field indicates the length (in bytes) of the parameter field subsequent to byte 2 (or byte 4 when using subpage format), excluding the page header of the Page Descriptor." This length is specific to each page code. The INIT must specify the same value as the page length reported by the HDD in the MODE SENSE or MODE SENSE EXTENDED command, except in cases it is described in each of the page descriptor descriptions in this item.

d.MODE SELECT parameters of the HDD

The parameter list configuration and its length that can be transferred to the HDD by the INIT in the MODE SENSE or MODE SENSE EXTENDED command are as shown in Table 4.13. If a "Page descriptor" that is not supported by the HDD is specified, the command is terminated with a CHECK CONDITION status (ILLEGAL REQUEST [=5] / Invalid field in parameter list [=26-00]), and all the MODE SELECT parameters transferred in the command are disabled.
