A disk drive comprising a disk, a head actuated over the disk, a read/write channel, a control processor, and a servo system is disclosed. The servo system is configured to read servo information from a servo wedge on the disk via the read/write channel, to generate first and second status information based on the read servo information, to output the first and second status information to the control processor, and to output first and second interrupt signals to the control processor, the first and second interrupt signals being spaced apart by a time delay. In response to the first interrupt signal, the control processor is configured to determine whether to release data from a host based on the first status information, and in response to the second interrupt signal, the control processor is configured to determine whether to release data from the host based on the second status information.
