The disk will then need to be formatted. Look in your software user
guide for further information, or in Windows Help. If you have a
CD-ROM drive fitted this will have to be renamed as drive E:, as a
second hard drive will be designated automatically as drive D: by
the operating system.
HDD control interface
There are two current designs of HDD control interface. The more
common type is the IDE (integrated drive electronics) which is built
into the motherboard. This requires comparatively simple electronics
on the motherboard and is a very efficient interface to the more
complex control electronics on the HDD itself. Access times and data
transfer rates are quite fast.
A secondary IDE interface, also on the motherboard, will control
drives such as the ATA-PI CD-ROM drive described on previous
pages. A single IDE interface can handle only two similar drives.
The second interface which can be fitted in the factory, is a plug in
SCSI (small computer system interface) controller. This will occupy
an expansion slot. It has its own control circuits and BIOS. There
are benefits in systems where multiple disk access is required, along
with repetitive access to large or complex data files.
The main advantage of the SCSI interface, that overcomes its higher
cost, is that it can handle several devices, not all of which need to be
similar. For example, 2 or 3 HDDs, a CD-ROM, a Tape drive, a
Scanner etc., could all be connected via a single SCSI ribbon cable in
the system. This does require great care and attention to detail when
installing and setting up new devices.
The basic installation requirements outlined above for an IDE HDD
will be the same for a SCSI drive, except that an 'ID' link will need
to be set on the SCSI drive instead of the master/slave link of the
IDE. Details of this will be supplied with the drive. SCSI devices
start from '0', which will be the 'bootable' HDD. There is a practical
limit on most SCSI interfaces of about six or seven logical devices.
