Hi Yogesh,
If you match Apple_HFS content, then produce Apple_HFS content, then
you would match recursively forever. It is advisable to either change
the partition type to com_spsoftindia_HFS on the specific volumes the
user is interested in enabling your software on, or if it needs to be
transparent to all volumes, then add a property on the media object you
produce, such that you can tell when it recurses in your probe() by
checking for the property, and failing the match if you see it.

Hi folks,
I had gone through the Mass storage driver pdf and according to the
example given in the pdf for Developing filter scheme driver write
sample filter scheme driver and it works fine for the diskimage which i
had created through hdiutil
In this example i specify "Content Hint" property as
MySoftwareCompany_MyContent in the IOKit personality for driver
matching
and read/write calls in my filter scheme driver works fine when i write
or read on this partition.
But when i specify "Content Hint" property as Apple_HFS which i think
is
the default content hint for the partitions created on MAC OS X and
load
my filter scheme driver which also has this property with the value
Apple_HFS i doesn't get the read/write IOLogs on the console and sees
only start and init function IOLogs repeatedly.
I have four partitons with Apple_HFS content hint which i had created
during installation of MAC OS X.
I want to know if i specify the "Content Hint" as Apple_HFS will my
filter scheme driver work for all the four partitions other than the
diskimage partition i have created using hdiutil???
Thanks in advance,
