Subj: Re: FWD: Tool for reading optical disks
I don't know much about optical devices or OSMS, so asking them
directly may be a better choice. The group handing the drives
has a VAXnotes conference somewhere. I don't know the hostname,
but the conference name is "OPTICAL". ASK_SSAG on SSAG may be
a better place to start.
There are three ways to read raw sectors:
o Install the SCSI CAM Layered Components OP driver and just
open the raw device and read sectors. If they have OSMS
installed, they'll have this driver installed.
o Write a program using the CAM User Agent to send SCSI Read
commands. Difficult, but not impossible.
o If the particular optical has a switch or mode page setting
that turns it from an optical device to direct-access device
use the base systme disk driver.
