IOCTL_DISK_IS_WRITABLE

1

Request IOCTL_DISK_IS_WRITABLE sending in storage device stack ONLY at mounted volume moment?
In minifilter I don’t receive IOCTL_DISK_IS_WRITABLE for FSDevice?

2

File systems don’t receive this request, they can indicate a read only
volume in the volume properties or on a file by file basis within the
file attributes. But in general the read_only characteristic is a
property of the underlying storage device not the file system itself.

Peter Scott,thanx for reply!

Request IOCTL_DISK_IS_WRITABLE sending in storage device stack ONLY at mounted
volume moment? Or this request can sending for each written operation?

It is sent per application requests so not exclusively at mount time nor
at every write.
