or cable select (CS). Normally you would set Parallel ATA hard drives to CS and use an
80-conductor cable.
To learn more about configuring PATA drives, see “ ATA Standards , ” p. 370 ( Chapter
7 ) .
Because Serial ATA drives connect to the SATA host adapter in a point-to-point config-
uration using a dedicated cable, there is no master, slave, or cable select setting as there
is with Parallel ATA drives. Note, however, that some SATA hard disk drives might have
jumpers to help solve compatibility issues, such as to lock a newer 3Gbps interface speed
drive into the slower 1.5Gbps mode to work around problems with some older 1.5Gbps
host adapters.
Drive Installation
Some computer cases use plastic or metal rails that are secured to the sides of a drive so
it can slide into the bay in the chassis. Other case designs have drive bays that directly
accept the drive via screws through the side supports, and no other hardware is necessary.
Some cases have tool-free designs with sliding latches to secure drives without screws.
Still others use a cage arrangement in which you first install the drives into a cage and
then slide the cage into the case (see Figure 19.28 ). If your case uses rails or a cage, these
are usually included with the case. With the proper mounting mechanism supplied via the
case, all you need is the bare drive to install.
