Disk Caching

[Guest]

Can disk caching be turned off for a given file or disk? Can this be done in the OS or at the application level in C? We tried FILE_ACCESS_MODE UNBUFFERED and it didn't work. Is this new to XP??

Because of the cache manager/file system design of Windows XP,
the file system cannot operate properly without the system cache enabled.
Windows XP uses the system cache to access it's metadata.
