Question of Copy protection

vbimport

#1

I was wondering how protections that use subchannel data (like Securom) work with a CD/DVD-Rom that is unable to read subchannel data.

It seems to me that the protection would not be able to verify any signature on an original disc if the subchannel can not be read by the drive. So how does the protection function in this case?

If a drive was unable to read subchannel data at all the game would not play.

I may be way wrong here but I think all drives can read subs just some cannot extract or copy subs in DAO.

If the drive cannnot read subchannel data, the game will run regardless.
