SAMSUNG HARD DISK DRIVE
The existing IDE specification enable to adhere only 2 drives and transferring speed was low.
But HDD efficiency are resulted to low the whole capacity according to getting system efficiency
Enhanced
higher. Enhanced IDE has specification of revised IDE-AT interface by current BIOS and 528Mb
IDE
barrier and we settled the low speed problem with this new spec. Same as Fast-IDE Interface
or Local Bus IDE-AT Interface.
EOL End of Life.
EPROM Erasable programmable read only memory.
EVT Engineering verification test.
File allocation table. Data table is recorded at the most outer side of disk, inform sector
FAT
location and order of each recorded file to Operating system.
FCI Flux change per inch. magnetization rotation density per unit inch.
Flux Change Per Inch. Magnetization rotating density per unit inch. Concerned with BPI, this
FCI/FCPI/Flu
value is decided by track has maximum radius. BPI is proportion to FCI according to difference
x Density
of coding method.
FDD Floppy Disk Drive. 5.25"/3.5" drive is used for PC
FILTER Components filtering particle from the flowed air to the inside/outside of HDA.
Firmware Hardware control program, this is stored in
Flash Among PROM of the memory for searching only which can re-write, memory chip enable to
Memory rewrite and erase the old contents electrically.
Flexure Control rising by Slider ABS, flying height of slider and make slider move to proper track by
Assembly connecting to head positioning mechanism.
Flux Density Flux density, the number of magnetic field pattern can be recorded on the disk surface.
Distance between Read/write head and disk surface. Air resistance due to disk rotation can
Flying
maintain this distance, the small flying height is, the large data recording density is, but it need
Height
more specified mechanical design.
Form factor Industrial specification decided diameter of Disk. 3.5", 2.5" in case of Samsung.
Recording the particular signal to divide track and sector and this information should be recorded
Format on disk in first before user want to store data. Be careful because formatting erase all recorded
information.
Formatted
Available HDD capacity after HDD formatting.
capacity
Flexible Printed Circuit, or PCC, inputted parts enable to flow current to the flexible material.
FPC

Half height One of the standard height specification of HDD and the real height is 1.6inch
Hard
Hard error is a continuous misreading due to defect of disk surface) and it can read correct
Error/Soft
data if in case of read again, we call this soft error.
