Fujitsu MBC2073RC, MBC2036RC, MBA3300RC, MBA3147RC, MBA3073RC specifications Defect data conditions

Command Specifications

3.Even if defect data of the type specified in the CDB do not exist in the defect list (P List or G List) (if the defect list is empty), "1" is displayed in the "PList" bit and the "GList" bit in the header transferred to the INIT corresponding to the specification in the CDB.

4.By the INIT issuing this command specifying "4" in the "Transfer Byte Length" field in the CDB, and by investigating the information in the header transferred by the HDD, it can know the length (number) of data included in the P List and G List.

5.Depending on the combination of defect data type specifications and format specifications, the following conditions exist concerning the transferred defect data, so caution is necessary.

Table 4.45 Defect data conditions

Defect List Format	PList	GList
Block Address Format	2)	2)
Byte Distance from the Index Format	1)	1), 3)
Physical Sector Address Format	1)	1)

1)Regardless of the size of the User Space, all the defect position information for the disk media other than the system space is reported. Defect position information is also reported for areas which cannot be clearly accessed from the INIT, such as the spare sectors for alternate blocks.

2)Logical data blocks which have undergone slip processing due to defective sectors, and logical data blocks which have undergone alternate processing, are reported. Defect position information is not reported for areas which cannot be clearly accessed from the INIT (areas which do not have logical block addresses) such as cylinders and sectors, etc. which are not used as User Space or CE Space.

3)The byte position which indicates the first byte in defective sector data is reported.
