Abstract

A manufacturing system for a data storage device including a non-networked manufacturing device configured to write manufacturing data into a data storage device reliability log in a memory of a data storage device, and a networked manufacturing device configured to read the manufacturing data from the data storage device reliability log in the memory of the data storage device.

Claims

1. A manufacturing system for a data storage device, the manufacturing system comprising:

a non-networked manufacturing device configured for use during a manufacturing process of the data storage device, the non-networked manufacturing device configured to write manufacturing data into a data storage device reliability log in a memory of a data storage device as the data storage device moves through the non-networked manufacturing device during manufacturing of the data storage device, wherein the data storage device reliability log comprises the manufacturing data and a self-monitoring analysis and reporting technology (“

SMART”

) log; and

a networked manufacturing device configured for use during the manufacturing process of the data storage device, the networked manufacturing device configured to verify that the data storage device is manufactured correctly by reading the manufacturing data from the data storage device reliability log in the memory of the data storage device and configured to erase the manufacturing data from the data storage device reliability log without erasing the SMART log, as the data storage device moves through the networked manufacturing device during manufacturing of the data storage device.

2. The manufacturing system of claim 1 wherein the networked manufacturing device is further configured to generate a manufacturing log from the manufacturing data.

3. The manufacturing system of claim 2 wherein the networked manufacturing device comprises a network connection unit configured to connect to the network, and transmit the manufacturing log to the network.

4. The manufacturing system of claim 1 wherein the non-networked manufacturing device is further configured to encrypt the manufacturing data, and the networked manufacturing device is further configured to decrypt the manufacturing data.

5. The manufacturing system of claim 4 wherein the non-networked manufacturing device is further configured to encrypt the manufacturing data using an identifier of the data storage device.

6. The manufacturing system of claim 1 wherein the data storage device reliability log is configured to be stored in a non-user data section of the memory in the data storage device.

7. The manufacturing system of claim 1 wherein the manufacturing data comprises data regarding whether the data storage device was passed or failed by the non-networked manufacturing device.

8. The manufacturing system of claim 1 wherein the non-networked manufacturing device comprises at least one of an initializer device, a duplicator device, or an audit device.

9. The manufacturing system of claim 1 wherein the networked manufacturing device comprises a verification device.

10. The manufacturing system of claim 1 wherein the networked manufacturing device is further configured to analyze the manufacturing data and pass or fail the data storage device based on the manufacturing data.

11. The manufacturing system of claim 1 wherein the non-networked manufacturing device prevents unauthorized access to the manufacturing data during manufacturing of the data storage device.

12. A method for manufacturing a data storage device, the method comprising:

writing, during a manufacturing process of the data storage device, manufacturing data into a data storage device reliability log in a memory of a data storage device using a non-networked manufacturing device in a manufacturing system, wherein;

the manufacturing data is written into the data storage device as the data storage device moves through the non-networked manufacturing device during manufacturing of the data storage device; and

the data storage device reliability log comprises the manufacturing data and a self-monitoring analysis and reporting technology (“

SMART”

) log; and

verifying, during the manufacturing process of the data storage device, that the data storage device is manufactured properly by reading the manufacturing data from the data storage device reliability log in the memory of the data storage device using a networked manufacturing device in the manufacturing system, and erasing the manufacturing data from the data storage device reliability log without erasing the SMART log, wherein the manufacturing data is read from the data storage device and erased as the data storage device moves through the networked manufacturing device during manufacturing of the data storage device.

13. The method of claim 12 further comprising generating a manufacturing log from the manufacturing data using the networked manufacturing device.

14. The method of claim 13 further comprising:

connecting to the network using a network connection unit in the networked manufacturing device; and

transmitting the manufacturing log to the network using the network connection unit.

15. The method of claim 12 further comprising:

the manufacturing data stored in the data storage device reliability log is used by a networked manufacturing device to verify the data storage device is manufactured correctly during the manufacturing process of the data storage device;

the data storage device reliability log comprises a self-monitoring analysis and reporting technology (“

SMART”

) log stored separately from the manufacturing data; and

the manufacturing data is erased from the data storage device reliability log without erasing the SMART log; and

a controller configured to read data from and write data to the memory.

24. The data storage device of claim 23 wherein the manufacturing data comprises at least one of initializer device data from an initializer device in a manufacturing system, duplicator device data from a duplicator device in the manufacturing system, or verification device data from a verification device in the manufacturing system.
