2.2.2 Cable-select option

Computers that use cable-select determine the master and slave drives by selecting or deselecting pin 28, CSEL, on the interface bus. Master and slave drives are determined by their physical position on the cable. To enable cable select, set a jumper on pins 5 and 6 as shown in Figure

2.Refer to your computer manual to determine whether your computer supports this option.

2.2.3 Alternate capacity jumper

Some older computers may “hang” at startup if their BIOS detects a hard drive that has values greater than either 4,092 cylinders or approximately

33.8Gbytes (32 GB). To eliminate this problem, the drive includes a capacity-limiting jumper that sets the drive’s default translation geometry to 4,092 cylinders (2.1 Gbytes) for models ST330621A, ST320413A, ST315311A and ST310211A. This limits the drive’s capacity to 2.1 Gbytes. The ST340823A is limited to 33.8 Gbytes (32 GB) when the alternate capacity jumper is used. To realize the full capacity of the drive, you can use third-party software such as DiscWizard or Disk Manager.

If the alternate capacity jumper is used on drives under 40 Gbytes, the drive’s true LBAs are found in ID words 60 and 61. On the 40-Gbyte drive, the alternate capacity jumper “freezes” words 60 and 61 at a value below the problem barrier point. The ATA Set Features subcommand F1H Report Full Capacity Available is used to “unfreeze” and fill the real values in words 60 and 61 after the subcommand is issued.

Windows 98 or newer versions are needed to support drives with capacities greater than 33.8 Gbytes.

2.2.4 Ultra ATA/100 cable

An 80-conductor 40-pin cable is required to run Ultra DMA mode 3, mode 4 and mode 5. This cable uses even-numbered conductors connected to the ground pins to improve signal integrity.

Notes:

1.The drive supports both host and drive cable detection. The host detects the 80-conductor cable by sampling pin 34, CBLID–, on the interface bus. The drive detects the 80-conductor cable by sensing a capacitor at the host side through the CBLID– signal. The result is reported in a Fast Rise Detected bit (bit 13 of word 93 in the Identify drive parameter block).

2.When using a 40-pin 80-conductor cable, attach the blue con- nector to the motherboard, the black connector to the master drive, and the grey connector to the slave.
