    摘要： A method and system of controlling access to a hardware or software feature provided by a host is disclosed. An application seeking authorization to access a feature transmits a credential and an index to a host agent within the host. The index is associated with the requested feature. The host agent reads credential validation data from a storage location corresponding to the index in a non-volatile storage device in communication with the host. The validity of the credential is determined based on the credential validation data, and an authorization is transmitted if the credential is valid. A third party can control the outcome of the validity determination by sending an instruction to the host to replace the credential validation data with invalid data that causes the validity test to fail. The third party can also control the non-volatile storage device data used by the application to calculate the credential.

    摘要： Systems and methods of identifying a file path of a removable storage device are disclosed. A method includes, at a host device that is coupled to the removable storage device, selecting a file path that is associated with the removable storage device by accessing a size associated with a root directory accessible to the host device, where the root directory corresponds to the removable storage device. The file path is selected based upon the size associated with the root directory. The selected file path is verified by initiating a memory access operation using the selected file path.

    摘要： In order to write data to a storage system accessible with a first and second file system, a manager receives a data write request associated with a file. The manager determines if a function supported by the second file system is needed to complete the write request. If so, the file is opened and extended with the first file system. The file is then opened and written to by the second file system. The file is truncated by the first file system, and closed by both file systems. If the second file system function is not needed, the file is opened, written, and closed by the first file system. In order to read data from a storage system using a function supported by the second file system, the second file system's cached storage system index is updated, then the file is opened, read, and closed by the second file system.

    摘要： Techniques are presented for sending an application instruction from a hosting digital appliance to a portable medium, where the instruction is structured as one or more units whose size is a first size, or number of bytes. After flushing the contents of a cache, the instruction is written to the cache, where the cache is structured as logical blocks having a size that is a second size that is larger (in terms of number of bytes) than the first size. In writing the instruction (having a command part and, possibly, a data part), the start of the instruction is aligned with one of the logical block boundaries in the cache and the instruction is padded out with dummy data so that it fills an integral number of the cache blocks. When a response from a portable device to an instruction is received at a hosting digital appliance, the cache is similarly flushed prior to receiving the response. The response is then stored to align with a logical block boundary of the cache.

    摘要： A file system and method of file access are disclosed. In a particular embodiment, a method is performed at a host device coupled to a non-volatile memory, where the host device includes a memory having a first file data structure. A first directory entry in a file directory of a file system is located where the first directory entry corresponds to a first file stored in the non-volatile memory. First data associated with the first directory entry, including first location data indicating a location of the first file in the non-volatile memory, is retrieved and stored in the first file data structure. A request to open the first file is received. In response, the first location data of the first file is retrieved from the first file data structure and data of the first file from the non-volatile memory is read. First metadata associated with the first file is extracted from the data read from the non-volatile memory.
