Hi there,
When I do a DefineDosDevice to introduce my virtual disk to the NT
system , I use the string :
“\Device\diskDriver\;L:\V0” where diskDriver is the name of my
‘disk’ driver (diskDriver.sys) , L: is the DosDevice
name and V0 is the volumeName .
when I do CreateFile(“L:”, … ) first time , I do get a
IRP_MJ_FILE_SYSTEM_CONTROL / IRP_MN_MOUNT_VOLUME
and there I create a volum DeviceObject , deal with Vpb etc .
But when I try to mount another disk of my kind by a DefineDosDevice
with the string L"\Device\diskDrive\;M:\V1"
and does CreateFile(“M:”,… ) then the I/O manager delivers to my FSD
the same previous DeviceObject of L: instead
of issuing a new IRP_MN_MOUNT_VOLUME for the new disk !
Any idea how to overcome the problem ?
thanks

“\Device\diskDriver\;L:\V0”
is not correct for DefineDEosDevice
Try:
“\device\diskdriver\L:”
