Let me save you some time! While you consider the time that I saved you with this... Consider that I pay for yallfind.com, my website, with Google supported ads. Surely I saved you enough time for a visit and if anything interest you. a click.
1. Name four ATA standards for interfacing with hard drives?
Parallel ATA, EIDE, Fast ATA, Ultra ATA, Ultra ATA/66, Ultra ATA/100, Ultra ATA/133 and Serial ATA(SATA)
2. What are the two data transfer modes used by hard drives?
DMA and PIO
3. What are the two types of parallel ATA data cables used with hard drives?
Under parallel ata, two types of ribbon cable are used. The 80-conductor ide cable has 40 pins and 80 wires Forty wires are used for communication and data, and an additional 40 ground wires reduce crosstalk on the cable. An older 40-conducror cable has 40 wires and 40 pins.
4. What is the name of the ATA standard that uses a serial data cable?
SATA- serial ATA cable, these standards use a serial data path rather tha traditional data path.
5. What are the two most popular spindle speeds measured in RPMs currently used for hard drives?
5400 and 7200 RPM's.
6. How does serial ATA help keep a computer case cool better that a parallel ATA?
Serial ATA are thin cables that don't hinder airflow inside a case as much as the wide parallel ATA cables do.
7. If a hard drive has three platters, how many heads does it have?
Six heads, two for each platter.
8. Given that there are 512 bytes per sector, calculate the hard drive storage for the following: heads=32, tracks (cylinders)= 1024, sectors/track =63.
1.0569GB which rounds up to 1.06GB
9. What are three modes that system BIOS can use to relate to hard drives?
CHS mode, ECHS mode, and LBA(Logical Block Addressing) mode also known as limitation mode. these mode are use by the bios to figure the hard drive space.
10. Which mode must be used for a 10 GB hard drive?
LBA (logical block addressing) mode
11. What is the ATA standard that changed the number of bits used to address data on a hard drive?
ATA/ATAPI-6 standard (aka ATA/100) allows for 48-bit addressing over the original 28-bits. This allowed for the breaking of the 137GB barrier limitation.
12. How does block mode give faster access to a hard drive? How can you disable block mode?
it allows multiple data transfers each time software request data. you can disable block mode in CMOS Setup
13. When installing a hard drive and a CD-ROM drive on the same IDE channel, which do you configure as the master and which as the slave?
Configure the hard drive as the master and the CD-ROM as the slave.
14. What are three ATA hard drive interface standards that do not use a 40-conductor hard drive cable?
atapi-4, atapi-5, atapi-6
15. Generally, which transfer mode is faster, DMA or PIO?
DMA
16. When two drives are connected to the same data cable connected to an IDE channel, how does BUIS know which drive controls the channel?
The jumpers on each drive have been set to either Master or Slave, or the drive jumpers have been sent to Cable Select the bios will select the first connector as Master and second connector as Slave
17. If a motherboard has two parallel ATA connections, how many EIDE devices can the system support?
The system will be able to support 4 EDIE devices, 2 devices per cable.
18. If a hard drive is too small to physically fit snugly into the drive bay, what can you do?
You can use the universal kit to snugly fit the hard drive into the drive bay.
19. How can you tell which side of a hard drive's data cable connects to pin 1 on the drive?
These PC cables have a notch or key on one side of plug and can only be inserted in one orientation in connector socket. If the notch is missing, you may also look for a small arrow mark on pin 1 of the cable plug. Other marking is that the ribbon or flat cable some times will have the first wire in a different color compared to rest of the cable.
20. If your BIOS does not support a large-capacity drive that you want to install what five choices do you have?
Let the Bios see the drive as a smaller drive
Upgrade the bios
Replace the motherboard
Use software that interfaces between the older bios and the newer drive
Use an ATA Controller card to provide the ATA connector and firmware substitute for the motherboard bios
21. Which ATA standard allows for serial ATA and serial attached SCSI to coexist in the same system?
ATA/ATAPI-7 -Serial SCSI standard is compatible with serial ATA drives in the same system
22. What is the name of the power connector used with floppy drives?
Berg connector
23. How many pins does a floppy drive cable have?
A standard floppy drive cable in a computer has 34 pins.
24. What was the underlying cause that prevented hard drives from breaking the 137 GB size barrier until the ata/atapi-6 standard was released?
The fact that the hard drive, the system BIOS, and the OS used 28 bits to communicate addresses to the data on the drive.
25. Why does the serial ATA drive sometime have two power connectors on the drive?
One power connector is for the SATA power cable and the other is for the standard power cable. Use one or the other depending on what power connectors you have available in your system but not both.
26. What is the name of the expansion card in a SCSI system the controls the SCSI bus?
The expansion card called the host adapter is responsible for managing all devices on the SCSI bus.
SCSI is a peer to peer interface.
27. Why is it not necessary to inform CMOS setup about the installation of a new hard drive?
Most drive standards are automatically detected.
28. Which has a faster interface to the system, and external serial ATA head drive or an external FireWire hard drive?
external serial ATA is six times faster
29. On a floppy disk, how many bits are used for each entry in the FAT?
The width of each entry in the FAT is 12 bits.
30. How can you tell if your motherboard chipset supports Ultra DMA mode?
Pentium motherboards that have the Intel TX Chipset, Pentium II motherboards starting with the Intel LX, BX and subsequent Intel Chipsets have UDMA capability. The chipset is displayed on system startup, which is called CMOS Setup. If unsure, consult system or motherboard documentation or manufacturer for chipset and UDMA performance verification.

USB
A computer store sold a total of 300 items last monthThe store sold six times as many hard drives as they did CD-ROM drivesand half as many floppy drives as hard drivesBased on this informationhow?
240 hard drives, 20 floppy drives and 40 CD-ROM drives.
What are the advantage of external drives?
One of the advantages of external hard drives is they are available in large capacities. Options are available for hard drives that have mass storing capability.

Hard drives, floppy drives, case fans, motherboard
How long do Solid State Hard Drives last?
There are two major types of solid-state hard drives - multi-level cell (MLC) and single-level cell (SLC) drives. MLC drives can generally last for five to six years before failure; on the other hand, SLC drives may potentially be able to last decades.

Portable hard drives work by interfacing with whichever computer they are connected to. In most cases, this connection is established by USB. Once the portable drives are connected they allow the user access to the data contained on it and the drive's storage capacity.

Can i use four 500GB SATA hard disks simultaneously on my Intel 102GGc2 motherboard. It has 4 slots of SATA drives. I am running Windows 7 Pro. 1GB RAM intel 2.66GHz pentium D 450 W power supply?
If your SATA controller can handle four drives (if it has four SATA ports, then presumably it can), then yes, you can use four drives.
