SATA hard drive cables

SATA data cable

Always use an HP approved SATA 6.0 Gb/s cable as it is fully backwards compatible with the SATA 1.5 Gb/s

drives.

Current HP desktop products ship with SATA 6.0 Gb/s hard drives.

SATA data cables are susceptible to damage if overexed. Never crease a SATA data cable and never bend it

tighter than a 30 mm (1.18 in) radius.

The SATA data cable is a thin, 7-pin cable designed to transmit data for only a single drive.

SMART ATA drives

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.
