Maxtor 80-160GB manual ATA Bus Adapter, CLJ Jumper Out

Installation

3.3.1.4Cylinder Limitation Jumper (CLJ)

For user capacities below 66,055,248 sectors (32GB), inserting the CLJ jumper limits the Number of Cylinders field 1 to a value of 16,383, as reported in IDENTIFY DEVICE data word. This allows software drivers to determine that the actual capacity is larger than indicated by the maximum CHS, requiring LBA addressing to use the full capacity.

A summary of these effects for the DiamondMax 17 80-160GB AT drives is shown in the following table:

	CLJ Jumper Out
	C=16,383
80GB	H=16
	S=63
	LBA = 156,301,488
	C=16,383
160GB	H=16
	S=63
	LBA = 312,581,808
