Abstract

Methods and removable storage devices are provided. Some such removable storage devices may include a file specifying a name of a program to be executed automatically by a host, may include settings for a secure storage area, where the settings are user-configurable, may include a secure partition that is not accessible by an operating system of a host, may be configured to cause a health of the removable device to be automatically checked when the removable device is coupled to a host, may be configured to cause a program for formatting the removable device to be executed when the removable device is coupled to a host, or may include a secure partition configured to store information so that formatting/reformatting does not alter the stored information.

Claims

1. A removable storage device, comprising:

a device port for coupling the removable storage device to a host; and

a file specifying a name of a program to be executed automatically by the host;

wherein the program causes the removable storage device to appear as non-removable to the host.

2. The removable storage device of claim 1, wherein the program is executed automatically in response to coupling the removable storage device to the host.

3. The removable storage device of claim 1, wherein the program is configured to check a health of the removable storage device.

4. The removable storage device of claim 1, wherein the program is configured to determine an integrity of a file system of the removable storage device.

5. The removable storage device of claim 4, wherein the program is configured to determine the integrity of the file system by validating entries of an allocation table of the removable storage device.

6. The removable storage device of claim 1, wherein the program is configured to look for errors in a file system of the removable storage device.

7. The removable storage device of claim 6, wherein the program is configured to attempt to fix any errors that are identified by the program.

8. The removable storage device of claim 7, wherein the program attempts to fix errors that are identified by the program in response to a user input.

9. The removable storage device of claim 6, wherein the program is configured to cause a report to be generated, indicating that the removable storage device is healthy in response to not identifying any errors.

10. The removable storage device of claim 1, wherein the file comprises a program configured to request a user input indicative of the user'"'"'s desire to format the removable storage device.

11. The removable storage device of claim 1, wherein the program resides on the host.

12. The removable storage device of claim 1, wherein the program resides on the removable storage device.

13. The removable storage device of claim 1, wherein the file is stored in a root directory of the removable storage device.
