re-write on rewritable CD-RW?

  QUADDRA 12:45 25 Jul 2006


So this is probably a simple problem but I don’t seem to be able to work it out.
I have a number of CD-Rws with music on them. My doughter wants to save some photos to a portable disk so I thought I could use these re-writable disks. I tried to erase / delete / format, write over the disks but it would not let me. The same message that the media is read only. So what am I doing wrong?

Thanks in advance.

You don't say how you tried to erase the disks. To do so you have to go into your CD writing program and find the option to erase rewritable disks.

You are normally given the option of quick erase or full erase. Usually, the quick erase works well and only takes a couple of minutes.

Nero or Roxio

Hi FelixTCat,
Thanks for the quick response.
The disks were written directly from itunes, I’ve tried using itunes to delete or even write over the top of the existing but it don’t want to know.

Hi Big Byte,

I used itunes to make the disk.
I have Pinnacle Instant CD/DVD supplied pre installed on a Mesh PC but it has stopped working and is asking for the installation disk that wasn’t supplied with the machine so I am waiting on a response from Mesh to see how to get it working again.

You could try downloading a trial version of Nero here click here and using it to erase the disk(s).

You could also try Microsoft's solution; see click here

Just found out a simple way to erase the contents of a cd-rw
Open windows Media player, most of us have it.
Click the burn tab
On the right window you will see a list of cd contents
Just above this window are 4 buttons
The last one on the right looks like a pencil eraser?, click it and all contents are erased.
All looks good but now every time I try to save something on it, it says write protected replace the disk.
Next question how do you turn off the write protection?

Looks like it needs to be re-formatted.

When creating a CD-R(write once) or a CD-RW (rewritable), there is a function called Session(at least that's what the Adaptec CD software calls it). If you want to write to a CD-R or CD-RW again (called creating a multi-session), you must leave the Session Open. If you close a Session, you can't write again to a CD-R.

If you close a Session on a CD-RW, you have to reformat the CD-RW, if you want to reuse it.

All you have done is erase the files on the disk.
you will need to format the disc with Nero INCD

try this first
If you are using Windos XP right click on the dirve with the CD-rw. In the menu that appears you should see a entry called "Erase this CD-RW". That will clear the data of the CD-rw and you can use the CD like a blank one.

If QUADDRA formats using INCD he will only be able to use a packet writing program to use the cd again.
He needs to use a program such as Nero to do a full erase of the disc.

Hi, Still having problems, tried a number of the above programs but still the same message :-
Error copying file or folder
Cannot copy ******** The disk is write protected.
Remove the write-protection or use another disk.

Any ideas?
