Installation
Maxtor DiamondMax 17 80-160GB AT Hard Disk Drive 3-7
3.3.1.4 Cylinder 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:

There are two ways you can configure a system to allow the DiamondMax 17
80-160GB AT hard disk drives to communicate over the ATA bus of an IBM
or IBM-compatible PC:
1. Connect the drive to a 40-pin ATA bus connector (if available) on the
motherboard of the PC.
2. Install an IDE-compatible adapter board in the PC, and connect the drive to
the adapter board.
