US 12,608,312 B2 · Data access control method of memory card and computer system

Abstract

A data access control method of a memory card and a computer system are provided. The computer system detects whether a memory card supports a first communication protocol version and a second communication protocol version. When the memory card supports the second communication protocol version, a access protection setting of the memory card is stored according to the first communication protocol version through a first driver. The access protection setting is used to restrict access to the memory card. The computer system unmounts the first driver. A disk corresponding to the memory card is set in an operating system of the computer system according to the access protection setting through a disk configuration service in 10 the computer system. The disk configuration service runs on the operating system, and the disk is configured with the access protection setting.

Dependent claims

A data access control method of a memory card, suitable for a computer system to access the memory card, wherein the data access control method of the memory card comprises:

detecting, by the computer system, whether the memory card supports a first communication protocol version and a second communication protocol version;
when the memory card supports the second communication protocol version, storing, by the computer system, an access protection setting of the memory card through a first driver according to the first communication protocol version, wherein the access protection setting is used to restrict access to the memory card;
unmounting, by the computer system, the first driver;
and
setting a disk corresponding to the memory card in an operating system of the computer system according to the access protection setting through a disk configuration service in the computer system, wherein the disk configuration service runs on the operating system, and the disk is configured with the access protection setting.

2 more elements

A computer system, comprising:

a storage used to store at least one program code corresponding to a first driver and a disk configuration service, wherein the disk configuration service runs on an operating system;
a control circuit used to be electrically connected to a memory card and detect a communication protocol version of the memory card;
and
a processor coupled to the storage and configured to load the at least one program code and the operating system to execute:
detecting whether the memory card supports a first communication protocol version and a second communication protocol version through the computer system;
when the memory card supports the second communication protocol version, storing an access protection setting of the memory card according to the first communication protocol version through a first driver, wherein the access protection setting is used to restrict access to the memory card;
unmounting the first driver;
and
setting a disk corresponding to the memory card in the operating system according to the access protection setting through the disk configuration service, wherein the disk configuration service runs on the operating system, and the disk is configured with the access protection setting.
