Flexible disk drive control method capable of preventing a seek error from occurring

摘要

In a flexible disk drive for driving a flexible disk (40) inserted in the flexible disk drive, when a power supply is turned on (step S1) and when the flexible disk drive is not inserted in the flexible disk drive (N of a step S7, N of a step S12), a seek operation is inhibited and a track 00 signal (TKO) is supplied to a host system just as if the flexible disk drive normally operate (step S8, step S14).
