Does anyone know if it is possible to temporarily disable
filesystem buffering? I am writing a disk utility that
attmpts to isolate intermittently bad sectors on an ide
hard drive and if the first read is successful, all subsequent
reads will also be successful when buffering is used.
Alternatively, is there a way in a user-space program running
as root to read a sector directly from a hard drive without
invalidating anything the kernel knows about the drive?
Thanks,
Dave Rivenburg
