Uhh.. no it don't. Using 2 instead of to and b instead of be just happens to make it more challenging infact to determine what you are trying to say.
However, what I believe you are tring to say is that you are putting in a CD, copying it by using the copy/paste function and getting an error. Here is what I have to say on that:
Sometimes when the disc is either dirty or scratched, it will not copy properly. Its because it is trying to read it as fast as it can, and it will cause errors from copying.
Also, if you copy and paste a CD, you can't mount it. Infact, it is the worst thing to do with CDs because really, its better to copy the iso.
Get a program that copies CDs to ISOs. Alcohol does this well and then you can mount it too. Make the ISO of the disc by using a slow read speed. This way, it will be able to use ECC in a better way (meaning that it should not get any errors unless the disc is REALLY dirty or scratched). Then you can mount it. If this is not your issue, please, for the love of god, think before you type so that we might comprehend what you are trying to say.
