Abstract

A storage device includes a recording medium having a user-area and a system-area. The storage device conducts a self-diagnostic test on a recording medium. When conducting the self-diagnostic test, a writing/reading unit performs writing of data in and reading of data from the system area at a user-area write/read frequency that is a frequency for writing of data in and reading of data from the user area.

Claims

1. A storage device including a recording medium having a user-area and a system-area, and that implements a self-diagnostic test, the storage device comprising:

a writing/reading unit that, in the self-diagnostic test, performs writing of data in and reading of data from the system area at a user-area write/read frequency that is a frequency for writing of data in and reading of data from the user area.

2. The storage device according to claim 1, wherein the user-area includes a plurality of sectors each corresponding to a different user-area write/read frequency, and

the writing/reading unit, in the self-diagnostic test, performs writing of data in and reading of data from the system area at each of the different user-area write/read frequencies.

3. The storage device according to claim 2, wherein the writing/reading unit, in the self-diagnostic test, performs writing of data in and reading of data from the system area at a frequency that is highest from among the different user-area write/read frequencies.

4. A control device that causes a storage device to perform a self-diagnostic test on a recording medium having a user-area and a system-area, the self-diagnostic control device comprising:

a writing/reading unit that, when causing the storage device to perform the self-diagnostic test, performs writing of data in and reading of data from the system area at a user-area write/read frequency that is a frequency for writing of data in and reading of data from the user area.

5. The control device according to claim 4, wherein the user-area includes a plurality of sectors each corresponding to a different user-area write/read frequency, and

the writing/reading unit, in the self-diagnostic test, performs writing of data in and reading of data from the system area at each of the different user-area write/read frequencies.

6. The control device according to claim 5, wherein the writing/reading unit, in the self-diagnostic test, performs writing of data in and reading of data from the system area at a frequency that is highest from among the different user-area write/read frequencies.

7. A method of performing a self-diagnostic test on a recording medium having a user-area and a system-area, the method comprising:

performing, in the self-diagnostic test, writing of data in and reading of data from the system area at a user-area write/read frequency that is a frequency for writing of data in and reading of data from the user area.

8. The method according to claim 7, wherein the user-area includes a plurality of sectors each corresponding to a different user-area write/read frequency, and

the performing includes, in the self-diagnostic test, writing data in and reading data from the system area at each of the different user-area write/read frequencies.

9. The method according to claim 8, wherein the performing includes, in the self-diagnostic test, writing data in and reading data from the system area at a frequency that is highest from among the different user-area write/read frequencies.
