This command moves the R/W heads to the cylinder specified in the task files.    The drive sets BSY and 
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.
