7 pins
How many pins are on the power connector of a SATA drive?
15 pins
What type of hard drive transfers data in parallel?
Parallel ATA (PATA)
How many pins are the connectors on an IDE drive?
40 pins
How many wires are on the IDE cables?
40 wires on the older versions.
80 wires on the newer versions.
What type of hard drive transmits data in full-duplex, meaning it can send and receive simultaneously?
Serial ATA (SATA)
How many pins are on a SATA data cable?
7 pins
How many pins are on a SATA power connector?
15 pins
What are the maximum data transfer rates for SATA?
Revision 1.0 - 1.5 Gb/s
Revision 2.0 - 3 Gb/s
Revision 3.0 - 6 Gb/s
Older SATA drives installed to newer SATA controllers can run:
Only at the speed of the drive.
The specifications of a hard drive are:
Capacity Data transfer rate Rotational speed Cache Latency
What are louder sounding hard drives that are often used in servers and power workstations that need high data throughput?
Small computer system interface (SCSI)
True or false:
A SCSI drive must be terminated at the end of each chain and each device it gets its own ID.
True
Hard drives are non-volatile.
Which means that any information stored on them cannot be lost when the computer is turned off.
What ID number does the SCSI controller normally use?
ID 7
What are the maximum data transfer rates for SCSI drives?
Ultra3: 160 MB/s
Ultra-320: 320 MB/s
Ultra-640: 640 MB/s
SAS (Serial Attached SCSI): 300 MB/s
What are the different ways to defragment a hard drive?
Disk Defragmenter,
Command line defrag,
Command line defrag -f, if you have less than 15% free space.
Several issues when troubleshooting hard drives are:
BIOS does not see the drive.
Windows does not see a second drive.
Slow reaction time
Missing files at startup
Noisy drive/lockups
What type of hard drive storage that has one or more hard drives installed into a device that connect directly to the network called?
Network attached storage (NAS)
How many pins are in the power connector for a floppy drive?
4 pin mini power connector
How many pins are in the data connector for a floppy drive?
34 pins
What happens if the data cable is upside down connected to a floppy drive?
The activity light will stay on.
What type of drive uses removable media in the form of magnetic tape cartridges and has a high capacity?
Tape drive
