You must have a CD-Rom drive that support RAW sector reads so that you can build a RAW image.

Regards, Max P.S. I've heard it is not legal to make images from copy-protected CDs, do not agry, 'cause in this case you can accuse the manufactures of knives when somebody used a knife for murder. -----Original Message----- From: bounce-ntdev-5529@lists.osr.com [mailto:bounce-ntdev-5529@lists.osr.com]On Behalf Of Eric Lee Steadle Sent: Tuesday, September 25, 2001 10:28 PM To: NT Developers Interest List Subject: [ntdev] RE: Virtual Miniport: Copy Protection -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Gary, While you certainly could be named in a lawsuit (anyone can and for no good reason), the aiding and abetting charge most certainly would be dismissed by any competent judge. The digital millennium copyright act aims to change that (they'd like to presume you guilty), but most everyone who cares about the subject believes that the supreme court will eventually find it flawed and large parts of it will be struck down. In any case, the ability of an end user to use their legally purchased media in a manner not consistent (or even conceived of) by the author is not grounds for a lawsuit or jail time. One of the most annoying things about any modern game you can purchase off the shelf is it's insistence on being IN the CD Rom tray while you're playing the game. This despite the fact that you chose "Full Install". While I'm gaming, I want to use my SPDIF CD Rom drive for what god intended - - to play music. You can't do that if the damned game wants its CD in there. The words I like to repeat are "fair use". Congress long ago said, and the Supreme Court agreed, that its OK to make copies of your licensed copyright material for your own personal use. This is why it's OK to make an audio tape of your CD so that you can listen to it in your car. This is also why it's OK to make a backup copy of your software. Nevermind the fact that the license agreement almost always says that you CAN make backup copies (so long as you don't use them simultaneously), the law says it first. I suspect that our friend Arun is developing a CD image mounting system whereby, I the copyright licensee can create an image of my (legally purchased) CD on my hard disk, run the Virtual CD software, and promptly lose the CD and it's associated hassles. The decision whether to use this kind of tool to violate copyright is with the end user -- right where it belongs. To that end, I offer the following information: http://www.daemon-tools.com/main.htm http://www.gamecopyworld.com/ Arun, In all of the documentation I've seen regarding the creation of CD image backups, it is imperative that the CD image be created with bad sectors in mind. The CD manufacturing, mastering, and duplication process is oblivious to bad sectors, but your CD rom reader is not, nor is the application that reads those bad sectors. The CD manufacturers that understand this are TDK and Plextor and they have made devices that will create images using a raw-bit read mode rather than a logical sector mode, allowing bad sectors, illegal TOCs, and other gimmicks to be burned to a CD. There are applications that are capable of creating this image, and unfortunately their names escape me at the moment. But I'll try and get back to you on which they are. I think your best bet is to try and obtain one of these programs and test your driver with an image created by it, rather than what you're using now. Mail me separately as I think this will develop into an off-topic conversation.
