Question | Answer |
---|---|
low level formatting | A process (usually performed at the factory) that electronically creates the hard drive tracks and sectors and tests for bad spots on the disk surface. |
operating system formatting | Formatting performed by the Windows Format program |
parallel ATA | An older IDE cabling method that uses a 40-pin flat or round data cable or an 80- conductor cable and a 40-pin IDE connector. See also serial ATA. |
PIO | A transfer mode that uses the CPU to transfer data from the hard drive to memory. PIO mode is slower than DMA mode. |
read/write head | A sealed, magnetic coil device that moves across the surface of a disk either reading data from or writing data to the disk. |
SCSI ID | A number from 0 to 15 assigned to each SCSI device attached to the daisy chain. |
serial ATA | An ATAPI cabling method that uses a narrower and more reliable cable than the 80-conductor cable. See also parallel ATA. |
serial ATA cable | An IDE cable that is narrower and has fewer pins than the parallel IDE 80-conductor cable. |
terminating resistor | The resistor added at the end of a SCSI chain to dampen the voltage at the end of the chain. |
zone bit recording | used by disk drives to store more sectors per track on outer tracks than on inner tracks. It is also called Zone Constant Angular Velocity (Zone CAV or Z-CAV or ZCAV). |
