Can CD-R be formatted?

What is the difference between CD-R & CD-RW. Why it is not possible to erase any file from CD-R? I want to know whether it is linked with hardware or software?

    CD-R can be formatted... ONCE, usually to UDF/MDF. Once it's formatted, it pretty much won't be of use to anything else.

    As others said, CD-R you can only write to ONCE (the portions you did NOT write to can still be written to later) Whereas CD-RW can be re-written / reformatted and erased.

    Why? That's the way CD-R works. The marks are actually BURNED onto the media by a laser. It cannot be unburned. Why do you think they are called "burners"?

    CD-RWs use a different technology (phase change) to record the on/off bits. It requires very different circuitry. CD-R is most similar to original CD standard, which is why CD-R is almost universally compatible whereas CD-RW compatibility must be specified.

    So to answer your last question: hardware.

    Technically you may format a CD-RW with the intention to erase it and use it back. yet you are able to format a CD-R in a feeling. some courses will allow you to 'practice' a CD-R so as which you will write to it 'on the fly'. yet this has very intense overhead (filespace) and would deliver approximately matters with different structures being waiting to examine it.

    No. CD-R means CD-Recordable...ONCE it is a WORM (Write Once Read Many) disc. CD-RW means CD-Re-Writable, which allows it to be written and erased several times.

    It's related to hardware. You can just cut whatever it is on a CD-R, so who uses it won't see those files, but they take physical memory.

    No. CD-R means that after you burn it, it is done. You can't do anything about it affter you burn it.

    CD-RW mans that you can burn it, but you can burn it again and again and it can be edited.
