Command Specifications

2.After changing anything in the "Block descriptor," "Format parameters (Page 3)" or "Drive parameters (Page 4)," with the MODE SELECT or MODE SELECT EXTENDED command, it is impossible to execute a command to access the data on the disk media until execution of the FORMAT UNIT command is completed, and a CHECK CONDITION status (MEDIUM ERROR [=3] / Medium format corrupted [=31-00]) is reported for all such commands.

The configuration and functions of the "Page descriptors" supported by the IDD are described in Section 4.1.

Note:

In the diagram that shows the configuration of each individual "Page Descriptor," the default column shows that parameter's "default" value and the "variable" column shows whether or not it is possible to vary that parameter ("1" indicates that it can be varied). The INIT can know those values and attributes by using the MODE SENSE or MODE SENSE EXTENDED command.

This command performs setting and changing of each type of parameter related to disk drive physical attributes, data format, timing of SCSI bus disconnect/reconnect processing and error recovery procedures, etc.

This command's function is the same as that of the Group 0 MODE SELECT command (Section 3.1.5), except that the format of its data transferred by the INIT differs partially from that of the (MODE SELECT) data format.
