Ultra ATA Drive Guidelines and Features

*If there are three or more devices, two or more of which are hard drives, two hard drives should

be attached to the primary controller first before following the General Attach Sequence Rule.

4.3.4 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.

■ When Ultra ATA and SCSI hard drives are mixed in the same system, the Ultra ATA drive

will become the boot drive unless the boot order is changed in Computer Setup (F10 Setup).

4.4 SMART

The Self Monitoring Analysis and Recording Technology (SMART) ATA drives for the HP

Personal Computers 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.
