Abstract

Systems and methods are provided for performing diagnostics on a removable media drive. An example system includes a monitoring unit configured to collect information about a media access to the media drive and a media access to a removable media contained in the media drive. The example system also includes a storage unit having a threshold table with at least one threshold value for the media access to the media drive. A processing unit is configured to compare the collected information of the monitoring unit to the at least one threshold value contained in the threshold table. The processing unit is also configured to determine diagnostic data relating to the removable media drive in accordance with the comparison.

Claims

1. A system for performing diagnostics on a removable media drive, the system comprising:

a monitoring unit configured to collect information about a media access to the media drive and a media access to a removable media contained in the media drive;

a storage unit having a threshold table with at least one threshold value for the media access to the media drive; and

a processing unit configured to compare the collected information of the monitoring unit to the at least one threshold value contained in the threshold table and configured to determine diagnostic data relating to the removable media drive in accordance with the comparison,

where the monitoring unit is configured to collect media session information in a media drive table where a media session begins with an insertion of the removable media into the media drive and concludes when the removable media is ejected from the media drive, and is configured to collect drive session information in a drive session table stored separately from the media session information, the drive session information being collected until the removable media drive is exchanged, and

where the processing unit determines the remaining lifetime by comparing data from the drive session table to the threshold values contained in the threshold table, and using a determination of an evolution of the readability of the removable media in the media drive based on the information stored in the different media tables.

2. The system of claim 1 where the monitoring unit is configured to generate a media drive table for each removable media inserted into the media drive.

3. The system of claim 1 where the monitoring unit is configured to collect a media serial number and to store the media serial number together with the media drive table of the media session.

4. The system of claims 1 where the monitoring unit is configured to first collect the media session information in a media session table, the processing unit being configured to transfer the data contained in the media session table to the media drive table of the media session when the removable media is ejected from the media drive, and to clear the media session table by when a new media is inserted into the removable media drive.

5. The system of claim 1 where the processing unit is configured to determine a remaining lifetime of the removable media drive in accordance with the comparison.

6. The system of claim 1 where the processing unit is configured to generate the media drive tables for each removable media session in a persistent area of the storage unit.

7. The system of claim 1 further comprising a drive handler configured to detect an eject event of the removable media and transmitting the eject event to the processing unit.

8. A method for generating diagnostic information for a removable media drive, the method comprising:

collecting information about a media access to the media drive and a media access to a removable media contained in the media drive;

providing a threshold table with at least one threshold value for the media access to the media drive;

comparing the collected information about the media access to the media drive and the media access to the removable media contained in the media drive to the at least one threshold value contained in the threshold table and determining diagnostic data relating to the removable media drive in accordance with the comparison a diagnostic information for the removable media drive in accordance with the comparison;

collecting media session information relating to a media session in a media drive table, where the media session begins with an insertion of the removable media into the media drive and concludes when the removable media is ejected from the media drive; and

collecting drive session information in a drive session table separately from the media session information, the step of collecting being performed until the removable media drive is exchanged.

9. The method of claim 8 further comprising:

generating a media drive table for each removable media inserted into the media drive.

10. The method of claim 8 further comprising:

collecting the media session information in a media session table;

transferring the data contained in the media session table to the media drive table of the media session when the removable media is ejected from the media drive; and

clearing the media session table when it is detected that a new media is inserted into the removable media drive.

11. The method of claim 8 further comprising:

determining the diagnostic information by comparing data from the different media tables and the drive session table to the threshold values contained in the threshold table.

12. The method of claim 8 further comprising:

determining the remaining lifetime of the removable media drive; and

including the remaining lifetime of the removable media drive as the diagnostic information.

13. The method of claim 8 where the step of collecting information includes the step of:

counting the number of starts or stops of a media reader used in the media drive for reading the removable media.

14. The method of claim 8 where the step of collecting information includes the step of:

counting the number of working hours.

15. The method of claim 8 where the step of collecting information includes the step of:

determining the number of drive resets.

16. The method of claim 8 where the step of collecting information includes the step of:

determining the number of read errors.

17. The method of claim 8 where the step of collecting information includes the step of:

determining the drive temperature.

18. The method of claim 8 where the step of collecting information includes the step of:

determining the number of media insertions in the removable media drive.
