Format table consists of the number of sectors ( 16 bits ) per track . Upper byte represents sector number,
and lower byte represents format type.
The drive supports only 00H format type. Intending to maintain compatibility with previous models, the drive
accepts any format type, but the function will not change.
Sector interleave is always set to one regardless of sector sequence in the format table. Data subsequent
to format table are handled as “Don't care”.

starts seek operation. After the completion of a seek operation, the drive asserts DSC

, negates BSY ,
and return the interrupt.
If CY, HD and SN registers show invalid address, “ID Not Found” error is reported and no seek operation
shall be executed. All commands related to data access possess Implied Seek function and don't need this
command.
