There are 2 main types of CDs: CD-Rs and CD-RWs.
* If the CD is a CD-RW (or CD+RW) then yes, you can wipe it and start again. To do this use any CD burning program: something like Nero would do fine. * CD-Rs are not erasable. However, if you originally created the disc with something like Nero, you may have been offered the option of "Starting a Multi-session disc" or something like that. If you chose that option, then you would be able to burn more files onto the CD until it is full, however you still would not be able to change or delete existing files.
It can be erased and used again, instead of buying new CD-R's just erase a CD-RW and put the new data on it.
A CD-R cannot be erased, once media is put on it, it cannot be taken off, but a CD-RW can be erased and resotred as many times as you want.
yes it can be written but unfortunatly it cannot be erased
A CD has a certain amount of memory and is blank until something is loaded or burned on it. When a program or file is burned on the CD, the CD no longer acts as a memory space but as a readable file. Every time that disc gets put in another computer, it will be read for the file that was burned on it.
It can be written and erased thoroughly.
It really depends on how hot the fire is... No really, burning a CD means that a laser is etching information on it. Most CD's are write once, meaning that you can etch(burn) info on the disk but when its full that's it. It cannot be reused. Re-writable disks are available that can be erased and written to again. So to answer your question, burning a disk in a CD drive will normally not damage it, but after you have 'burned ' what you want on it then the disk can only be used to access the info on it and cannot be burned again.
CD-R can't be formatted. (erased)
i burned the CD
The most obvious reason is because you burned the CD incorrectly.
To reformat a CD-RW use a disk utility application, or an application like Toast. Reformatting will erase all media on the CD-RW. The CD-RW can then be re-written, or burned again with new information.
A CD Drive reads CDs.A CD-R drive writes to CD-R discs. Rewrite not possible.A CD-RW drive writes to CD-RW discs. Rewrite capable.CD drive can only read a CD and not write to it, the drive is called a CD-ROM drive. CD-R is a recordable drive, it will burn to CD-R discs, which can only be burned to one time.CD-RW drives support CD-R and CD-RW, which is the ability to burn to CD-RW discs, which can be burned to, and erased, hundreds of times.
CD-r's are permanent CDs and cannot be erased.
