Hi MMC and Fuji,

Final MMC 5 says:

Table 320 — INQUIRY Data for ATAPI and USB Drives

Response Data Format 0011b

HiSup 0b

NormACA 0b

However, Mt Fuji 6 and 7 says:

The ATAPI Transport Version field shall contain 03h to comply with this version of the Specification. This field

indicates the version of the ATAPI Transport that is being used. For more information on the transport, see the INCITS

T13/1153D standard. For a SCSI logical unit this field is defined by the SCSI SPC-2 standard.

A Response Data Format value of 02h indicates that the data shall be in the format specified in this Specification.

Response Data Format values less than two are obsolete. Response Data Format values greater than two are

reserved.

-*-

Note: A value of 3 for ATAPI Transport Version would match NormACA 1b and HiSup 1b. The response data format values contradict as well.

Our Microsoft WLK test is currently verifying versus the MMC requirement above, thus the Fuji compliant devices get failed. Standard committees, which is the right specification here?

Also, how does the host know if it should decode according to SCSI or according to ATAPI for the Fuji specification of inquiry response?

With regards,

David Burg.
