Method for processing file system service requests in a computer having an attached disk drive that can reproduce stream data and non-stream data

Apparatus for processing file system service requests in a computer having an attached disk drive with stream and non-stream modes of_operation that in response to commands from the computer can write data to or read data from disk locations to reproduce stream data and non-stream data, comprising:

• means for responding to a first file system service request by,
• recording whether the first file system service request is for non-stream or stream data,
• associating a first set of disk locations of the disk drive with the file system service request, and
• preparing a first command that requires access to the first set of disk locations for causing the disk drive to operate in a stream or non-stream mode in accordance with the first file system service request, the first command including control data categorizing the command as a non-stream access command or as a stream access command in response to the recording;
• and
• means for transmitting the first command to the disk drive.
