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.

Pseudo-mounting unformatted removable media

An invention is disclosed for automatically preparing removable media for content, such as by automatically formatting media such as CDs and DVDs. A drive type is determined for a drive present on a computer system. The drive type defines characteristics of the drive. In addition, a media type is detected for removable media, such as a compact disc or floppy disk, present in the drive. Similar to the drive type, the media type defines characteristics of the removable media. Based on the drive type and media type, the removable media is automatically prepared for content in response to receiving a request to write to the removable media.

Methods and an apparatus for a caching mechanism which improves system performance are provided. One exemplary method includes reading files in response to a request from an operating system. Then, copies of the read files are stored in a cache where the cache is located within a random access memory of the computer. Next, frequency factors are assigned to each of the files stored in the cache, where the frequency factors indicate how often each of the corresponding files has been accessed by the operating system. Then, the frequency factors are scanned in response to a capacity of the cache being attained. Next, a least frequently and least recently used file is identified. Then, the least frequently and least recently used file is eliminated to liberate capacity of the cache.
