Abstract

A storage medium driving device including a storage medium having a user area and a non-user area, and to record master boot record information that is backed up in the non-user area, and a controller to compare the backup master boot record information with master boot record information read from the user area, and to restore master boot record information recorded in the user area according to the comparison results.

Claims

1. A storage medium driving device comprising:

a storage medium including a user area and a non-user area, and to record master boot record information that is backed up in the non-user area; and

a controller to compare the backup master boot record information with master boot record information read from the user area, and to restore the master boot record information recorded in the user area according to the comparison result.

2. The storage medium driving device of claim 1, wherein the controller compares the backup master boot record information with master boot record information read from the user area based on a value of a flag that is set when the backup master boot record information has been read from the non-user area.

3. The storage medium driving device of claim 1, wherein, when the controller reads the backup master boot record information from the non-user area, the controller sets as a first value to a flag that the backup master boot record information has been read, and when the comparison between the backup master boot record information with master boot record information read from the user area is performed, the controller converts the flag to a second value.

4. The storage medium driving device of claim 3, wherein, when the controller receives a read command from a host and the flag is the second value, the controller does not compare the backup master boot record information with master boot record information read from the user area.

5. The storage medium driving device of claim 4, wherein, when the backup master boot record information is determined by the controller to be inconsistent with the master boot record information read from the user area, the controller copies the backup master boot record information to the user area when transmitting the backup master boot record information to the host to restore the master boot record information in the user area.

6. The storage medium driving device of claim 5, wherein when the backup master boot record information is determined by the controller to be consistent with the master boot record information read from the user area, the controller transmits the master boot record information read from the user area to the host.

7. The storage medium driving device of claim 1, wherein, when the backup master boot record information is determined by the controller to be inconsistent with the master boot record information read from the user area, the controller copies the backup master boot record information to the user area while transmitting the backup master boot record information to the host to perform the restoring.

8. A method of restoring a master boot record of a storage medium in a storage medium driving device, the method comprising:

comparing backup master boot record information read from a non-user area of a storage medium with master boot record information read from a user area of the storage medium; and

when the backup master boot record information is inconsistent with the master boot record information read from the user area, restoring the master boot record information recorded in the user area by using the backup master boot record information.

9. The method of claim 8, wherein the comparing is performed based on a value of a flag that is set when the backup master boot record information has been read from the non-user area.

10. The method of claim 8, wherein the comparing comprises:

setting a flag to a first value when the backup master boot record information has been read from the non-user area; and

converting the flag to a second value when the comparing of the backup master boot record information with the master boot record information is performed.

11. The method of claim 10, wherein the comparing further comprises:

when a read command is received from a host and when the flag is the second value, skipping the comparing of the backup master boot record information with the master boot record information.

12. The method of claim 10, wherein the restoring is performed such that when the backup master boot record information is inconsistent with the master boot record information read from the user area, the backup master boot record information is copied to the user area when being transmitted to the host to restore the master boot record information recorded in the user area.

13. The method of claim 12, wherein the restoring of the master boot record information further comprises:

transmitting the master boot record information read from the user area to the host when the backup master boot record information is consistent with the master boot record information read from the user area.

14. The method of claim 8, wherein the restoring is performed such that when the backup master boot record information is inconsistent with the master boot record information read from the user area, the backup master boot record information is copied to the user area when being transmitted to the host to restore the master boot record information recorded in the user area.

15. A non-transitory computer readable storage medium that includes computer-readable codes that, when executed by a computer, performs the method of restoring a master boot record, the method comprising:

comparing backup master boot record information read from a non-user area of a storage medium with master boot record information read from a user area of the storage medium; and

when the backup master boot record information is inconsistent with the master boot record information read from the user area, restoring master boot record information recorded in the user area by using backup master boot record information.

16. A method of restoring a master boot record of a storage medium in a storage medium driving device, the method comprising:

determining whether backup master boot record information matches master boot record information stored in a first area of the storage medium; and

when the master boot record information matches master boot record information of the first area, restoring the master boot record information of the first area with the backup master boot record information.

17. The method of claim 16, further comprising:

when the backup master book record information matches master boot record information stored in the first area of the storage medium, transmitting the master boot record in formation of the user area to a host that is communicatively coupled to the storage medium driving device.

18. The method of claim 16, further comprising:

transmitting the backup master boot record information to a host that is communicatively coupled to the storage medium driving device.

19. A storage medium driving device comprising:

a storage medium including a first area having master boot record information, and a second area having backup master boot record information; and

a controller to compare the backup master boot record information of the second area with the master boot record information of the first area, and to restore master boot record information recorded in the first area using the backup master boot record information when the master boot record information of the first area does not match the backup master boot record information of the second area.
