Additional Drive Application Notes

When replacing a hard drive, the replacement should be of the same type (Ultra ATA -33,
-66, or -100) as that being removed to retain the same level of performance.
Your system supports a maximum of three drives. A second hard drive can be install in your
system; however, you MUST remove the diskette drive to create an available drive bay.
Some graphics cards (such as the nVIDIA Quadro4 400 NVS) will require the removal of the
diskette drive (or hard drive, if installed) in bay 1. See Chapter 5 for Drive Positions.
SMART Drives
The Self Monitoring Analysis and Recording Technology (SMART) ATA drives for HP
workstations have built-in drive failure prediction that warns the user or network administrator of
an impending failure or crash of the hard drive. The SMART drive tracks fault prediction and
failure indication parameters such as reallocated sector count, spin retry count, and calibration
retry count. If the drive determines that a failure is imminent, it generates a fault alert.

Drive Capacities

The combination of the file system and the operating system used in the workstation determines
the maximum usable size of a drive partition. A drive partition is the largest segment of a drive
that may be properly accessed by the operating system. A single hard drive may therefore be
subdivided into a number of unique drive partitions in order to make use of all of its space.
The table that follows identifies the capabilities and restrictions imposed on the workstation by
the combinations of BIOS, file and operating systems.
