Chapter 5 IDE RAID Setup
Appendix
RAID Terminology
Physical Drive
The physical drive is the IDE hard disk that is connected by cable to
the HyperDisk100 card. The hard drive contains platters which are
coated with material so that allows them to record data
magnetically. Another important feature is the read/write head,
which hovers over the surface of the platter. You can store and
access data much more quickly on a hard disk than on a floppy
disk.

Logical Drive
A logical drive is a partition in a physical array of disks that is made
up of contiguous data segments on the physical disks. A logical
drive can consist of an entire physical array or part of an array.
Disk Rebuild
You rebuild a disk drive by recreating the data that had been stored
on the drive before the drive failed. Rebuilding can be done only in
arrays with data redundancy, such as RAID level 1.IDE RAID
automatically and transparently rebuilds failed drives with user-
definable rebuild rates. If a hot spare is available, the rebuild starts
