Abstract

A method and an apparatus for copying data of a disc drive are provided. The method includes: determining whether the first disc drive has a predetermined jumper pin connection by identifying which of a plurality of jumper pins in a jumper block of the first disc drive are connected, the jumper block being used to determine an operation mode of the first disc drive; transmitting a copy command from the first disc drive to the second disc drive if the first disc drive has the predetermined jumper pin connection; and copying data recorded in the first disc drive to the second disc drive in response to the copy command. Accordingly, it is possible to copy data recorded in a first hard disc drive (HDD) to a second HDD without the aid of an additional host.

Claims

1. A method of copying data from a first disc drive to a second disc drive, comprising:

determining whether the first disc drive has a predetermined jumper pin connection by identifying which of a plurality of jumper pins in a jumper block of the first disc drive are connected, the jumper block being used to determine an operation mode of the first disc drive;

transmitting a copy command from the first disc drive to the second disc drive if the first disc drive has the predetermined jumper pin connection; and

copying data recorded in the first disc drive to the second disc drive in response to the copy command.

2. The method of claim 1, wherein the transmitting of the copy command comprises:

determining whether the first disc drive is set to a source mode in response to a first source mode setting command if the first disc drive has the predetermined jumper pin connection; and

transmitting the copy command from the first disc drive to the second disc drive if the first disc drive is set to the source mode.

3. The method of claim 2, wherein the first disc drive is set to the source mode by recording a predetermined data value in a source mode recording zone of the first disc drive in response to the first source mode setting command.

4. The method of claim 3, wherein the source mode recording zone comprises a non-volatile recording zone.

5. The method of claim 2, wherein the first source mode setting command is transmitted to the first disc drive by a host.

6. The method of claim 2, wherein the first source mode setting command is transmitted to the first disc drive by a disc drive which has the predetermined jumper pin connection and is set to the source mode.

7. The method of claim 1, wherein the copying of the data recorded in the first disc drive to the second disc drive is carried out in a Serial Advanced Technology Attachment (SATA) interface manner.

8. The method of claim 2 further comprising setting the second disc drive to the source mode after the copying of the data recorded in the first disc drive to the second disc drive.

9. The method of claim 8, wherein the second disc drive is set to the source mode in response to a second source mode setting command transmitted thereto by the first disc drive.

10. An apparatus for copying data from a first disc drive to a second disc drive, comprising:

a first disc drive to transmit a command to copy data recorded therein if it recognizes that it has a predetermined jumper pin connection by identifying which of a plurality of jumper pins in a jumper block thereof are connected, the jumper block being used to determine an operation mode of the first disc drive;

a second disc drive to copy the data recorded in the first disc drive in response to the command transmitted by the first disc drive; and

a communication path to connect an interface unit of the first disc drive and an interface unit of the second disc drive.

11. The apparatus of claim 10, wherein the first disc drive transmits the command if it further recognizes that it is set to a source mode in response to a source mode setting command.

12. The apparatus of claim 11, wherein the first disc drive recognizes whether it is set to the source mode with reference to a data value recorded in a source mode recording zone thereof.

13. The apparatus of claim 12, wherein the source mode recording zone comprises a non-volatile recording zone.

14. The apparatus of claim 12, wherein the source mode recording zone comprises a flash memory zone.

15. The apparatus of claim 12, wherein the data value recorded in the source mode recording zone of the first disc drive is different from a data value recorded in a source mode recording zone of the second disc drive.

16. The apparatus of claim 11, wherein the first disc drive sets the second disc drive to the source mode if the copying of the data recorded therein to the second disc drive is complete.

17. The apparatus of claim 10, wherein the first and second disc drives are SATA hard disc drives (HDD).

18. The apparatus of claim 10, wherein the communication path comprises a communication path connecting SATA HDDs.

19. The apparatus of claim 15, wherein the first disc drive cancels its setting to the source mode if it recognizes that the predetermined jumper pin connection is cut off.

20. A disc drive, comprising:

determination means for determining an operation mode of the disc drive; and

data sending means for sending data to a destination disc drive upon a predetermined operation mode of the disc drive being detected by the determination means.
