EIDE hard-disk drives must be physically formatted, partitioned, and logically format-
ted before they can be used to store data. Every hard-disk drive purchased from Dell
is physically formatted before it is sent to you.
Drives with a storage capacity of 8.4 gigabytes (GB) or smaller use the file allocation
table (FAT) 16 file system. For the Windows 95 operating system, drives with a stor-
age capacity greater than 8.4 GB use a single partition with the FAT 32 file system.

NOTE: When using Windows 95 or Windows NT with the FAT 16 file system, the pri-

mary partition for each hard-disk drive can be no larger than 2GB. Extended partitions

can be larger than 2 GB, but each logical drive within a n ex tended partitio n must be n o

larger than 2GB.

If you ever have to partition and logically format an EIDE hard-disk drive, use the pro-
gram(s) provided by the operating system.

To use small computer system interface (SCSI) devices in your Dell computer, you
must have a SCSI host adapter card, which comes with its own SCSI cable. This cable
can be used to attach a variety of SCSI devices (hard-disk drives, tape drives, and so
on). The SCSI host adapter configures the devices attached to it as one subsystem—
not as independent devices.
Although SCSI devices are installed essentially the same way as other devices, their
configuration requirements are different.

For details on configuring a SCSI subsystem, refer to the docu mentation that came
with the SCSI devices and/or the host adapter card. The fol lowi ng subsections offer
some general guidelines.
