Hi,
I have tried the simple SFilter sample, modified to attach to
all volumes (i.e. not just FILE_DEVICE_DISK_FILE_SYSTEM), and if I run
aHead InCD, the system cannot access the removable media (including
floppies).
I’m just guessing that the way SFilter attaches might be the
problem, but…
aHead hasn’t responded to this, yet, so if anyone has found this
problem, and knows a workaround, or has any ideas, please, let me know.

I saw something similar with Adaptec DirectCD. If something else
installed as upper filter above cdrom.sys, some programs (FAR manager for
example) sometimes can’t recognize media changing. Strange, but opening CD
drive in “My Computer” always cure the problem. I see that the explorer
issues some strange (?) PnP IRPs in that case.

Yes, similar thing:-)

In InCD case, the CD drive cannot even be seen, as I wrote:-)

One of the versions of this product was just buggy - after hibernate, the CD drive disappears.
