Flux
the tiny magnetic fields in an HDD can switch north/south polarity back and forth through a process called what
Flux Reversal
what are groups of flux reversals called?
Runs
What data endoding system allows any combination of ones and zeroes to be stored in a preset combination of about 15 different runs?
RLL (Run Length limited)
What range is the maximum run length for PRML drives?
16 to 20 fluxes
What are the only two technologies HDD manufacturers used to move the actuator arms?
Stepper motor
Voice Coil
Which HDD technology moved the actuator arm in fixed increments?
stepper motor
Which HDD technology uses a permanent magnet surrounding a coil on the actuator arm?
Voice coil
what are the 3 critical values that define a hard drive’s geometry?
(CHS)
1. Cylinders
2. Heads
3. Sectors per track
Older HDD's would spread data a little farther apart
once it got to a particular cylinder. What was this cylinder called?
Write Precompensation Cylinder
Older hard drives had a real problem with the fact that sectors toward the inside of the drives were much smaller than sectors toward the outside.
What was the unused cylinder used as a “parking place” for the read/write heads of older HDD's called?
Landing zone
used only on stepper motor HDD's
What type of Hard Drives use memory chips to store data instead of platters, arms etc.
SSD (Solid State Drive)
What are the 2 type of ATA drives?
1. SATA
2. PATA (Older technology)
How many wires do a PATA ribbon cable have. (2 Sizes)
What does the colored stripe down one side of an IDE ribbon represent?
Pin 1
The real layout of the CHS inside an HDD is called what?
Physical geometry
The "fake" CHS described to the CMOS by the onboard circuitry of an HDD was called what?
Logical geometry
What the name of the ATA2 extension that enabled non–hard drive devices such as CD-ROM drives and tape backups to connect to the PC via the ATA controllers?
Advanced Technology Attachment Packet Interface (ATAPI)
How many pins do ATAPI drives have?
40-pins
What new feature did ATA3 techonology introduce?
(S.M.A.R.T.) Self-Monitoring,
Analysis, and Reporting Technology
what is S.M.A.R.T Techonology?
It helps predict when a hard drive is going to fail by monitoring the hard drive’s mechanical components
What new feature did ATA4 techonology introduce?
Ultra DMA
Which Ultra DMA mode transfered at 16.7 MBps?
Mode 0
Which Ultra DMA mode transfered at 25.0 MBps

Mode 2
Which Ultra DMA mode transfered at 44.4 MBps
Mode 3
Which Ultra DMA mode transfered at 66.6 MBps
Mode 4 aka ATA/33
A system with INT13 extensions can handle up to what size drives?
137 GB
what is the maximum length of SATA cables?
40 Inches
What device allows you to use a PATA drive with a SATA ribbon cable?
SATA Bridge
what disk-optimization feature for SATA drives enables faster read and write speeds?
Native command queuing (NCQ)
http://en.wikipedia.org/wiki/Native_Command_Queuing
What is the process of connecting a device directly to another device then to another device then on and on called?
Daisy Chaining
The device at the end of a SCSI daisy chain must be have what setting enabled?
Termination
Some devices have this feature automatically enabled
What is Raid 0
Disk Striping
http://www.prepressure.com/library/technology/raid
Which level of RAID requires at least two drives, does not provide redundancy to data and if any one drive fails, all data is lost?
RAID 0—Disk Striping
http://www.prepressure.com/library/technology/raid
What is RAID 1
Disk Mirroring/Duplexing
http://www.prepressure.com/library/technology/raid
Which level of RAID stores data twice by writing them to both the data disk and mirror disk?
RAID 1
http://www.prepressure.com/library/technology/raid
Which level of RAID data had blocks subdivided (striped) and written in parallel on two or more drives had an additional drive to store parity information?
RAID 3
http://www.prepressure.com/library/technology/raid
On an ATA66 IDE cable what color is the connector that goes to the controller on the motherboard?
Blue
ATA 5 Cable
On an ATA 66 IDE ribbon cable what color is the connector that goes to a Slave drive?
Grey
ATA 5 IDE; has 40 pins
On an ATA66 IDE ribbon cable what color is the connector that connects to a Master drive?
Black
just think of 40 acres and a mule (Master / Black)
Data is transferred to disks by independent read and write operations (not in parallel). Which level of RAID is this?
instead of a dedicated parity disk, parity information is spread across all the drives.
What is the maximum amount of SCSI devices can you put in a daisy chain?
15 Devices
