Method to improve speed of hard disk diagnostics

Hard disk capacity on personal computers is growing at a rapid pace. 80 to 100 gigabyte files are now common and the growth in size is expected to continue into the foreseeable future. Hard disk test programs (diagnostics) traditionally use sector by sector, track by track logic and test the entire hard disk. This can lead to very long run times on large hard files and for this reason, these programs are often not run by customers or service personnel. This leads to hard files sometimes being replaced for no good reason. A method for speeding up hard file diagnostics without loosing effectiveness is needed.

Our invention would have the disk diagnostics use a list of file types along with the operating systems file allocation directories to create a list of sectors that are actually being used and are critical to system operation. This list would be much smaller than the total disk size so an effective test of the disk would run much faster.

The diagnostic program would be supplied with a default set of file extensions for file types that were critical to system operation (e.g. .com, .dll, .exe). It would search through the operating system's file directory structures to determine which physical sectors was associated with every file with these file extensions. These would be the only sectors tested.

A facility would be provided for the user to add additional file types to be included in the diagnostic checks. An in...
