Abstract
Techniques for reducing mount time for a peripheral device connected to an external host device are presented. In some implementations, when a connection is detected, file system data is pre-fetched before a request for such data is sent by the external host device. This allows faster access to the file system data used for initiating read/write communications. In other implementations, in response to a data access command from the external host device, a reply message is delayed from the peripheral device to prevent data access command failures. This delayed response prevents the external host device from pausing before attempting subsequent communication requests.
