Hi,everyone!
I have used command “diskperf -YV”(you can use command “diskperf H”
for detail) and reset my computer,DeviceTree report:
…
-------------DEV \Device\HarddiskVolume3
|ATT Attached:(unnamed) -\Driver\Diskperf
|[FT] File System:(unnamed) -\Filesystem\Fastfat
-------------DEV \Device\HarddiskVolume2
|ATT Attached:(unnamed) -\Driver\Diskperf
|[FT] File System:(unnamed) -\Filesystem\Fastfat
-------------DEV \Device\HarddiskVolume1
|ATT Attached:(unnamed) -\Driver\Diskperf
|[FT] File System:(unnamed) -\Filesystem\Ntfs
…
Yesterday,I compiled the sample DDK\src\storage\filters\Addfilter and
used command “addfilter /device \HarddiskVolume2 /add diskperf.sys” to
filter logical disk d:.After I doing this and boot my computer,My disk d:
disappeared.
Before doing that,I have shut down diskperf with command"diskperf -N" .
DeviceTree then reported:
…
-------------DEV \Device\HarddiskVolume3
|____[FT] File System:(unnamed) -\Filesystem\Fastfat
-------------DEV \Device\HarddiskVolume2
|____[FT] File System:(unnamed) -\Filesystem\Fastfat
-------------DEV \Device\HarddiskVolume1
|____[FT] File System:(unnamed) -\Filesystem\Ntfs
…
After I doing that,logical disk d: disappeard .DeviceTree report:
-------------DEV \Device\HarddiskVolume3
|____[FT] File System:(unnamed) -\Filesystem\Fastfat
-------------DEV \Device\HarddiskVolume2
-------------DEV \Device\HarddiskVolume1
|____[FT] File System:(unnamed) -\Filesystem\Ntfs
Why File System on d: disappeard?Why command “diskperf -YV” can load
diskperf.sys correctly but “addfilter /device \HarddiskVolume2 /add
diskperf.sys” done incorrectly?
Anyone can tell me How to install a volume disk filter driver correctly?
Thanks a lot.
