Backing up multiple CD-ROMs to a single BD-R

[Black5Lion]

So I want to back up a bunch of CD-ROMs (~20 of them) to a single BD-R to save up on space.
I have ImgBurn but it won't work :/ It goes all the way to 99% then fails, I think the CDs might be encrypted.
So how can I copy them?

I would make ISOs files first then backup the isos.

For me I do this on linux with dd:

dd if=/dev/sr0 of=MyISO.iso bs=2048 conv=notrunc

The problem is I can't make ISOs ImgBurn fails at 99% :/
I don't have any linux distro installed currently Is there a way I can do that from windows 7?

What type of cds are you trying to read? If they are games or other types of copy protected discs then you will need clonecd or another tool capable of backing up protected cds, depending on the type of protection.

Some old course CDs, they're a pain to use since there are around 20 of them :/
I'll try CloneCD thanks
