SATA hard drives
The Self Monitoring Analysis and Recording Technology (SMART) ATA drives for the HP Personal Computers
h
ave 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.
Table 3-3 SATA hard drive characteristics
Serial ATA hard drive characteristics
Number of pins/conductors in data cable
7/7
Number of pins in power cable 15
Maximum data cable length 100 cm (39.37 in)
Data interface voltage
dierential 400 mV–700 mV
Drive voltages 3.3 V, 5 V, 12 V
Jumpers for conguring drive N/A
Data transfer rate 6.0 Gbps
Always use an HP-approved SATA 6.0 Gbps cable because it is fully backwards compatible with the SATA 1.5
Gb
ps drives. Current HP desktop products ship with SATA 6.0 Gbps hard drives.
SATA data cables are susceptible to damage if overexed. 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, seven-pin cable designed to transmit data for only a single drive.
Cable management
Always follow good cable management practices when working inside the computer.
● Keep cables away from major heat sources like the heat sink.
● Keep cables clear of sliding or moveable parts to prevent them from being cut or crimped when the parts
ar
e moved.
● When folding a at ribbon cable, never fold to a sharp crease. Sharp creases can damage the wires.
● Do not bend any cable sharply. A sharp bend can break the internal wires.
● Never bend a SATA data cable tighter than a 30 mm (1.18 in) radius.
● Never crease a SATA data cable.
