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
overflexed.
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.
