Abstract

An invention is disclosed for automatically formatting removable media. A default media image is generated in computer memory in response to detecting unformatted media in a computer drive. The media image includes default file system structures for the media. In response to receiving a request to read the media, data is returned based on the default file system structures. However, the removable media is automatically prepared for content in response to receiving a request to write information to the media, wherein the default media image in memory is committed to the media.

Claims

1. A method for automatically formatting removable media, comprising the operations of:

generating a default media image in computer memory and entering a pseudo-mount state in response to detecting unformatted removable media in a computer drive, the default media image including default file system structures for the unformatted removable media;

returning pseudo-data based on the default file system structures in the default media image in response to receiving a request to read the unformatted removable media to give an impression that the unformatted removable media is formatted and mounted; and

automatically preparing the unformatted removable media for content in response to receiving a request to write information to the unformatted removable media, wherein the default media image is committed to the unformatted removable media.

2. A method as recited in claim 1, further comprising the operation of writing the information to the removable media after the default media image is committed to the unformatted removable media.

3. A method as recited in claim 1, further comprising the operation of modifying the default media image to include the information requested to be written prior to committing the default media image to the unformatted removable media.

4. A method as recited in claim 1, further comprising the operation of analyzing the removable media to detect a file system present on the removable media.

5. A method as recited in claim 4, further comprising the operation of mounting the removable media when a predefined file system is detected on the removable media.

6. A method as recited in claim 4, further comprising the operation of determining the removable media is audio media when the removable media includes non-zero data and a file system is not detected on the removable media.

7. A method as recited in claim 1, wherein the removable media is a compact disc.

8. A method as recited in claim 1, wherein the removable media is a digital video disc.

9. A method as recited in claim 1, wherein the removable media is a floppy disk.

10. A file system driver recorded on a computer readable medium for use in conjunction with an operating system, the file system driver comprising:

a code segment that, when executed by a computer, detects an unformatted removable media in a computer drive and in response to the detecting, generates a default media image in computer memory and enters the unformatted removable media into a pseudo-mount state, the default media image including default file system structures for the unformatted removable media;

a code segment that, when executed by a computer, returns pseudo-data based on the default file system structures in response to receiving a request to read the media to give an impression that the unformatted removable media is formatted and mounted; and

a code segment that, when executed by a computer, automatically prepares the unformatted removable media for content in response to receiving a request to write information to the unformatted removable media, wherein the media image is committed to the media.

11. A file system driver as recited in claim 10, wherein the information is written to the removable media after the default media image is committed to the unformatted removable media.

12. A file system driver as recited in claim 10, wherein the default media image is modified to include the information prior to committing the default media image to the unformatted removable media.

13. A file system driver as recited in claim 10, further comprising a code segment that analyzes the removable media to detect a file system present on the removable media.

14. A file system driver as recited in claim 13, wherein the file system driver mounts the removable media when a predefined file system is detected on the removable media.

15. A file system driver as recited in claim 13, wherein the file system driver determines the removable media is audio media when the media includes non-zero data and a file system is not detected on the removable media.

16. A file system driver recorded on a computer readable medium for automatically formatting removable media, comprising:

a code segment that, when executed by a computer, analyzes media to detect a file system present on the media in response to detecting removable media in a computer drive;

a code segment that, when executed by a computer, mounts the removable media when the file system detected on the removable media is a predefined file system;

a code segment that, when executed by a computer, detects an unformatted removable media in a computer drive and in response to the detecting, generates a default media image in computer memory and enters the unformatted removable media into a pseudo-mount state, the default media image including default file system structures for the unformatted removable media;

a code segment that, when executed by a computer, returns pseudo-data based on the default file system structures in response to receiving a request to read the unformatted removable media to give an impression that the unformatted removable media is formatted and mounted; and

a code segment that, when executed by a computer, automatically prepares the unformatted removable media for content in response to receiving a request to write information to the unformatted removable media, wherein the default media image is committed to the media.

17. A file system driver as recited in claim 16, wherein the information is written to the removable media after the default media image is committed to the unformatted removable media.

18. A file system driver as recited in claim 16, wherein the default media image is modified to include the information prior to committing the default media image to the unformatted removable media.

19. A file system driver as recited in claim 16, wherein the removable media is a compact disc.

20. A file system driver as recited in claim 16, wherein the removable media is a digital video disc.

21. A file system driver as recited in claim 16, wherein the removable media is a floppy disk.
