SCSI filter driver

NTDEV

Anyone know if it is possible to deploy a SCSI filter driver without
rebooting. I want to capture I/O commands to a CDROM drive, and relay
stasticial data to a windows app.

Any help, or suggestions would be much appreciated.

Cheers

Hi, Lee:

I have developed an ecryption filter driver for CD-ROM drives as a lower
filter for that kind of devices, so I manage the drives using SCSI commands.
It’s possible to install the filter without rebooting (in somes cases, it
could depend on the drive… and I have seen CD-ROM units that force to
reboot :-(. The same is applicable in the remove process: sometimes, the
drive (or saying more correctly, the driver) doesn’t support removing (by
using the corresponding SetupDiXXX function).

I hope I have answered your question.

Regards,

Jose Vicente.

Doubts. On NT4, it is impossible.
On w2k+, this requires stopping and the restarting the CD devnode,
and, if stop fails, the installer suggests the reboot.

Yes, but it is complex. You would need an FS filter driver.
