Systems and methods for detecting and compensating for runt block data transfers

A method for detecting a runt block transfer in a data transfer processing system, comprising:

• requesting a data transfer from a source to a host;
• transferring the data from the source to the host and decrementing a counter in a controller upon each data transfer;
• and
• continuing to transfer data until a value in the counter is nonzero but less than a value in a register that tracks the amount of data to be transferred in a single data phase.

A data transfer processor stored on a computer-readable medium, the data transfer processor being executable by a controller, comprising:

• logic configured to request a storage medium to transfer at least one data sector of a plurality of data sectors remaining in a request;
• logic configured to determine whether sectors remaining in the request are evenly divisible by a defined block size;
• and
• logic configured to interrupt a data sector transfer request when a number of data sectors requested is not evenly divisible by the block size.

A system for detecting runt block transfers, comprising:

• a host device for setting a size of data blocks;
• a storage medium for storing data in data sectors;
• and
• a runt block transfer system operatively coupled between the host device and the storage medium, the runt block system adapted to transfer data sectors between the host device and the storage medium while the data sectors are evenly divisible by block size.

A system for detecting runt block transfers, comprising:

• means for setting a size of data blocks;
• means for storing data in data sectors;
• and
• means that couples the means for setting the size of data blocks to the means for storing data in data sectors, the means adapted to transfer data sectors between the means for setting the size of data blocks and the means for storing data in data sectors while the data sectors are evenly divisible by the block size.
