CD-to-CD copy VS All-Files copy ?

[winglesslight]

Hi
When I copy files like 1GB to another directory, doesn't PC ever miss a bit?
Do you also know if copying all the files from one CD to another is as good as disc-to-disc copy when burning a CD?
Which is better?
Thank you very much whoever replies.

Answer to question 1:

No the drive doesn't miss even a single bit. Error correction algorithms see to that. There is a incredibly small chance that it will happen anyway though, like 1 in 10 to the 15th power, chance that it will happen (the math is approximate). Or perhaps I should say that 1 out of every 10 to the 15th power bits could be lost.

Answer to question 2:

Whether you want to file copy or disk copy depends on what you are needing to do. If you want to, say... pirate a Windows XP CD (why you would want to do that is beyond me) then you would want to do a DISK to DISK copy (duplicate the entire disk, bit for bit). If you want to copy some of the files from one disk to another and don't need the two disks to be identical, then use file copy.

Supposing I burn a copy of Windows XP CD by copying all the files, what does it miss from the original CD, which makes the copy of CD useless?

that call-microsoft key, maybe the CD has some copy protection scheme which can be overcomed by using software like cloneCD.

Copying all the files won't necessarily result in a given file ending up in the same place physically on the copied CD. One method of copy protection would be to request a file located at a specific physical location rather than by directory structure. While I don't claim to know any specific CDs that use this method, I can't see any reason why it wouldn't work.
