The READ BLOCK LIMITS command requests that the drive return its limits for Block Length. The READ BLOCK LIMITS data shown below will be sent during the DATA-IN phase of the command. The command does not reflect the currently selected block size, only the available limits. MODE SENSE returns the current block size. 2 bytes is the minimum and 8 Mbytes byte is the maximum block size which the unit can support.

Table 6-71: READ BLOCK LIMITS Data

Bit	7	6	5	4	3	2		1	0

4	(MSB)		Minimum Block Length Limit (00 04h)
5									(LSB)

GRANULARITY: This field indicates the block size granularity of the logical unit and the recording format. For this logical unit, the value is 2, indicating a granularity of 2**GRANULARITY.

The maximum block length limit and minimum block length limit field values are shown in Table 6-71.
