Abstract
A system for delaying the release of a memory space holding a data block in a disk drive controller until an acknowledge signal is received. The present invention is implemented in a disk drive controller having a memory buffer. The disk drive controller receives a request for data from a host device. The disk drive controller then reads the data block from the disk and stores the data block in the memory buffer. The data block is then transmitted to the host device. The host device then either transmits an acknowledge signal or a busy signal. The disk drive controller does not release the data block unless an acknowledge signal has been received.
