Cable-Select Option; Alternate Capacity Jumper - Seagate Barracuda ATA III Family Product Manual

Barracuda ATA III Family Product Manual, Rev. B

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 on page 18. 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 disc
drive with a capacity greater than 33.8 Gbytes (32 Gbytes). The 40-Gbyte
ST340824A limits the drive's capacity to 33.8 Gbytes (32 Gbytes) when
the alternate capacity jumper is used. To access the full capacity of the
drive, you can:
•
Update the BIOS
•
Use third-party software such as DiscWizard
•
Use a third-party host adapter
For drives with capacities greater than 33.8 Gbytes, the alternate capac-
ity jumper changes the total available LBA sectors to 33.8 Gbytes to solve
issues with some BIOS during power on. The ATA Set Features subcom-
mand "F1 Report Full Capacity Available" causes Identify Data words
H
60 and 61 to report the full capacity. See Section 3.1.3 on page 31 for
more details on the Set Features command.
Windows Me, Windows 98 or newer versions are needed to support
drives with capacities greater than 33.8 Gbytes.
