- Is a misnomer, not applicable to IBM's or Clones
* A "WORM" Drive
- Only refers to the type of transport mechanism used in some of the older hard-drives

- Can erase and re-write (or write-over), the data on the media used
- Both 2 & 3 are correct
* An "MO" Drive
- Is a fairly recent technology for writing data by laser
- Can erase and re-write the data on the medial used
- Both 1 & 2 are correct
- Is a misnomer, not applicable to IBM's or Clones
* "Logical" Drive Assignments
- Allow for higher capacity assignments than physical assignments
- Is accomplished with FDISK, and allows for organization of subject material on the drive
- Is only possible up to Drive "E"
- Is only used when there are multiple disk-drives
* "Interleave"
- Refers to the logical vs physical sector assignments on any floppy or hard disk drive
- Allows for more efficient data transfer to or from the media
- Must be always be set to 1:1
- Both 1 & 2 are correct
* The term "Cylinders"
- Refers specifically to the number of heads
- Refers to the number of sectors available per head
- Refers to the arrangement of tracks accessed during a single physical positioning of the heads
- Refers to the total number of sectors available on the entire disk
* "Blocks" or "Clusters"
- Refers to the number of subdivisions available on a disk
- Refers to the group of sectors that represent a subdivision of the disk
- May refer to a portion of sub-units of a file group on a disk
- Choices 1,2, & 3 are all correct
* "Defragging" a Hard-drive
- Should be done occasionally (or often), to improve overall run-time efficiency
- Should only be done as a last resort
- Is a method of re-sectioning a hard-drive
- Should only be done when "Clusters" have been lost
* "Low-Level-Formatting"
- Should be performed whenever a new operating system is installed
- Is only done at the factory, during manufacture
- Should not be attempted on "IDE" type drives without special software.
- Cannot be accomplished on "SCSI" type drives
* "High-Level-Formatting"
- Should never be attempted on "IDE" type drives
- Can be used to re-structure the logical drive assignments of a hard-drive
- Can be accomplished on a single logical drive assignment, without disturbing other logical assignments
- Cannot be accomplished on "RLL" type drives
* "RLL" Encoded Drives
- Cannot be low-level-formatted with an "MFM" Controller
- Will have less capacity than if formatted with an "MFM" Controller
- Have approximately 50% more capacity than if formatted with an "MFM" Controller
- Have slower data access than if formatted as "MFM"
* The curent 5-1/4" disk-drive, known as the "DS/DD", has
- 80 tracks & 9 sectors/track
- 40 tracks & 15 sectors/track
- 40 tracks & 9 sectors/track
- 80 tracks & 18 sectors/track
* The current 3-1/2" disk-drive, known as the "DS/DD", has
- 80 tracks & 9 sectors/track
- 40 tracks & 15 sectors/track
- 40 tracks & 9 sectors/track
- 80 tracks & 18 sectors/track
* The curent 5-1/4" disk-drive, known as the "DS/HD", has
- 80 tracks & 9 sectors/track
- 80 tracks & 15 sectors/track
- 40 tracks & 9 sectors/track
- 80 tracks & 18 sectors/track
* The curent 3-1/2" disk-drive, known as the "DS/HD", has
- 80 tracks & 9 sectors/track
- 40 tracks & 15 sectors/track
- 40 tracks & 9 sectors/track
- 80 tracks & 18 sectors/track
* The 5-1/4" disk-drive, known as the "DS/QD", has
- 80 tracks & 9 sectors/track
- 40 tracks & 15 sectors/track
- 40 tracks & 9 sectors/track
- 80 tracks & 18 sectors/track
* The physical positioning of the heads over a specific track location is identified as
- Track mapping
- Logical Partitioning
- Cylinders
- Skew
* The logical versus physical location of sectors within a track is known as
- Track partitioning
- Skew
- Sector Partioning
- Track Mapping
* Most current operating systems and trends in software allow
for large capacity disk access,
but many setups still utilize ( physical / logical ) partitioning of the hard-drives.
These are simply assignments of the divisioning
of the hard-drive.
True / False
* The physical location of the heads of a hard-drive over a specific track location is identified as "_____________", rather than tracks, because of multiple heads.
* The current 5-1/4" disk-drive, known as the "DS/DD", has ____ tracks, ____ sectors, and has a capacity of _____ Kb
* The current 5-1/4" disk-drive, known as the "DS/HD", has ____ tracks, ____ sectors, and has a capacity of _____ Kb
* An almost forgotten 5-1/4" disk-rive, that has 80 track, "DS/DD", is called a ________-Density Drive.
* The current 3-1/2" disk-drive, known as the "DS/DD", has ____ tracks, ____ sectors, and has a capacity of _____ Kb
* The current 3-1/2" disk-drive, known as the "DS/HD", has ____ tracks, ____ sectors, and has a capacity of _____ Kb
* During disk-drive alignment, the use of a standard alignment disk that has two signals on adjacent tracks, will show up on an oscilloscope as a special pattern like opposing simultaneous sine-waves, called the "_________- _______", to allow adjustment of head centering on the correct track.
