Windows 7 - Backing up a DVD

Of late my laptop's DVD-ROM has been giving a lot of problems to me. It isn't being able to read CDs/DVDs. Each time I have to eject the disc, then insert it and do the entire process a lot of times for the CD/DVD to be read.

This problem has irritated me for a while now. There are many games which need the CD/DVD to be inserted, and each time when I change the discs, it takes away at least 5-6 minutes.

Is there a way by which I can back up the discs in my HDD and play the games without inserting each CD/DVD every time?

And the problem is DVD specific. For instance, the DVD of Ashes Cricket 09 is read in 2-3 attempts but that of NBA 2K11 takes at least 7-8 attempts for the laptop to read the disc. Is it a problem with my laptop or the DVDs?

And I tried installing Alcohol 120% and Daemon Tools, but the installation process keeps on asking me to reboot. After a reboot, it gives the same message.
I read somewhere that there are some issues of SPTD drivers on Windows 7 but couldn't really find a solution to it.

Any sort of help will be appreciated.
Thanks.

Will the drive read anydisk? It could be the drive is bad. I don;t know a way to test this other than replacing it.
Here are SPTD drivers.

You can try to extract an .iso image of the disk(s) with UltraISO. Then you can use it to mount that image to a virtual drive, just like you have a separate drive.

All the discs are read perfectly except the two I mentioned. And I use VirtualClone Drive to mount images, but I need a software to create the images.

I read that only Alcohol 120% can be used in my case as the two discs are protected by SecuROM and so creating an image won't work unless created by Alcohol 120%.

And I've already downloaded the driver available in the link. I had downloaded the first one, 'SPTD for Windows 2000/XP/2003/Vista/Windows 7 (32 bit)' but the installation issues for Alcohol 120% persist.

This will do it.
Probably you have 2 bad disks? Do you need a SPTD driver?
