Some questions about Fastfat.sys driver?

Dear All sirs:

Please help me about the questions as follows:
(1).Do someone tell me what’s the fastfat.sys functionality? I just found out that it has the function about FAT32…
(2).After I compilered the fastfat.sys(in IFS->wxp folder), I just copy it into \system32\drivers to cover the original one, should I switch off the System File Protection feature?
(3).How do I trace the IRP code when if I installed the fastfat.sys driver succeedly?
(e.g.what action do I operate that can make the debug message show in DebugView to observe the fastfat.sys working?)

Best Regards,

parkerlived.

This is a file system driver for fat32.

(2).After I compilered the fastfat.sys(in IFS->wxp folder), I just copy it
into \system32\drivers to cover the original one, should I switch off the
System File Protection feature?

Yes, you should. But there is a more simple solution - provide a path to
your driver instead replacing the system one.

(3).How do I trace the IRP code when if I installed the fastfat.sys driver
succeedly?

See FatDebugTraceLevel, it is used as a filter. Set it to any combination of
DEBUG_TRACE_* .

FAT and FAT32 support for Windows.

(2).After I compilered the fastfat.sys(in IFS->wxp folder), I just copy it

\system32\drivers to cover the original one, should I switch off the System
File
Protection feature?

Yes, or better name in MyFastFat.sys and add ImagePath value to
…\Services\FastFat registry key.
