Abstract
A method is provided including: generating a virtual block device including a file allocation table area located in an internal storage of an electronic device, and a cluster heap area located in a memory card that is inserted in the electronic device; and mounting a file system of the memory card using the generated virtual block device.
Claims18
A method in an electronic device, comprising:
- detecting, by a processor, whether a backup boot record is present in a boot record area of an internal storage of the electronic device and identical to a boot record stored in a boot record area of a memory card inserted into the electronic device;
- when the backup boot record is present and identical, generating a virtual block device in the internal storage by synchronizing a boot record area of the virtual block device with the boot record area of the internal storage and synchronizing a file allocation table (FAT) area of the virtual block device with a FAT area of the internal device, and synchronizing a cluster heap area of the virtual block device with a cluster heap area of the memory card;
- when the backup boot record is absent or nonidentical, generating the virtual block device by copying the boot record stored in the boot record area of the memory card to the boot record area of the internal storage and copying a FAT of the memory card to the FAT area of the internal storage;
- and
- mounting a file system of the memory card using the generated virtual block device.

An electronic device comprising:
- an internal storage;
- and
- a processing circuitry configured to:
- detect whether a backup boot record is present in a boot record area of an internal storage of the electronic device and identical to a boot record stored in a boot record area of a memory card inserted into the electronic device;
- when the backup boot record is present and identical, generate a virtual block device in the internal storage by synchronizing a boot record area of the virtual block device with the boot record area of the internal storage and synchronizing a file allocation table (FAT) area of the virtual block device with a FAT area of the internal storage, and synchronizing a cluster heap area of the virtual block device with a cluster heap area of the memory card;
- and
- mount a file system of the memory card using the generated virtual block device.
