Drive Groups, Drive Packs
A group of individual disk drives (preferably identical) that are logically tied
to each other and are addressed as a single unit. In some cases this may be
called a drive “pack” when referring to just the physical devices.
All the physical devices in a drive group should have the same size;
otherwise, each of the disks in the group will effectively have the capacity of
the smallest member. The total size of the drive group will be the size of the
smallest disk in the group multiplied by the number of disks in the group.
For example, if you have 4 disks of 400MB each and 1 disk of 200MB in a
pack, the effective capacity available for use is only 1000MB (5x200), not
1800MB.
Drivers
A software routine that receives I/O requests from higher levels within the
operating system and converts those requests to the protocol required by a
specific hardware device.
ECC
Error Correcting Code, a method of generating redundant information which
can be used to detect and correct errors in stored or transmitted data.

EPROM
Erasable Programmable Read Only Memory, memory which can be erased
