Problem with CD-RW discs

I bought some CD-RW discs some time ago and have not had cause to use them until recently. When I came to use them, to back up some data for teaching, the copier, Easy CD Creator 4, began the copying process and then after a while ejected the disc and then closed the ejector door. Writing to the disc continued for a while but then stopped with the error message "Writing not complete, CD is write protected."

This was a bit of a surprise as I thought that I could write to the discs, after all they are CD-RW.

I was advised to format the disc using Direct CD. This I tried but got the message "You cannot use this drive for this CD, formatting not complete".

I have e-mailed TDK, the disc manufacturer, but so far I have not had a response. I don't want to put the info onto floppy disc as it would take too many discs, but I need the info on something other than paper so that I can use it in a lesson.

Anyone got any ideas?

Also does anyone know of the merits of Nero over Easy CD creator. I have been looking at this but reviews I have read seem biased. I have not any problems with Easy CD Creator before now and the software writes to CD-R with no problems. According to the live update for the software all is up to date.

Thanks

in basics when writing to rewritable CD's.....

You can either use a "packet writing" programme, such as "Direct CD", (or the equivalent from Ahead/Nero, called InCD), or use a more "conventional writing prog, such as Easy CD Creator, or Nero...

If you arre using a "packet writing" prog then the CD has to be formatted first. (The formatting is known as UDF, Universal disc format.) When this is done then the formatted CD is written to in exactly the same way as you would write to a floppy, eg "drag and drop". The formatting process has other consequencies;

1) To read such a CD the PC must have software that can read UDF discs. This will be achieved by having either "Direct CD" or "InCD" installed, or a generic UDF reader. (and probably others of which I am unaware)

2) Formatting takes some space, so a formatted 650M disc only has about 500M useable space.

3) A disc so formatted cannot be used with "conventional" CD writing software, (Nero, or Easy CD Creator), as you have discovered without first being completely erased.


I hope this helps. I add 2 riders...

I know that Windows XP has it's own CD writing capabilities that is different to both the above but I don't know how it behaves.

I know that some "packet writing" software will also format CDR's (ie, not rewritable discs). Again I'm not sure of details of this.

I hope this helps!

I know lots' of folk report reliabilty problems with CDRW discs... This has not been my experience, at all, when using them formatted/packet writing. I do this all the time.

I don't often use them with "conventional" software. When I did, in the distant past, I did have failures.

Thanks for the advise.

I have used the scan CD facility and it reports all OK. I have used Direct CD to wipe the CD and then tried to format it but it still doesn't work, when it tries, I get the error message saying "you cannot use this drive (D) for these CDs". This is puzzling me because I the drive is set to "D" works fine for all installing etc., from other CDs and lets me write to CD-R.

I wouldn't have bothered with CD-RW just for back up generally, but what I want on the CDs for teaching purposes have updates fairly regularly and I didn't want a big wad of CD-Rs cluttering my briefcase if one or two CD-RWs would do.

I tried the drive with some other CDs and as above works fine, I also backed up some other stuff to CD-R which worked fine. So I don't know whether it is a software problem or a CD problem. Update for software reports all is up to date.

Thanks

I have tried another disc from the pack (of 10) and it won't have that either. I am getting Nero at the weekend so I will give it a try on that and also I will try my brothers PC, he too runs ME, and he as both Nero and Easy/Direct CD.

Thanks again

that when you get Nero you will also need to install the "InCD" programme if you want to use the packet writing technique.

I THINK I'm correct in saying that you MUST install Nero before InCD. It's not that it wont work without it, but when InCD installs it looks to see if Nero is installed and is registered. I fit doesn't see a registered installation of Nero it wont install InCD.

As usual, I'm open to correctionon this.. it's along time since I had to do it!

(And thanks for that pointer The Sack!)

Nero can be used with CD-Rs in multisession form - once the disk is full switch to a new disk. It's particularly handy for storing small programs, utilities, updates, patches etc.

I've had no problems with CD-RWs, which I have never formatted, but the real difference is that they are not as reflective as CD-Rs, hence the problems many users have with them being read properly, especially if they have been burned to several times.

The latest versions of Nero - the very last one of Nero 5.5 is 5.5.10.42 - can be used with virtually any rewriter; one of the main reasons for the constant updates by ahead was to ensure that new drive models were supported.

Been to the Roxio site and looked for updates, apparently all updated, so I don't know. I am going to get some other CD-RWs from my brother and try one of those.

I have never had trouble with any TDK product before, in fact it is my first choice for ALL media formats.

Got Nero and installed it fine, but it won't recognise my CD-RW/DVD combo for burning. It is shown on the list but there is a "no entry" icon on it. All I get is the Image File option for burning CDs. I suspect that I have been given an OEM version, although my brother did give me the CD to install Nero, and the Nero toolkit shows my drive manufacturer name, lists drivers etc., etc..

Before installing Nero I remvoved Easy CD Creator and Direct CD to avoid any conflicts.

If I have an OEM version I will probably have to buy a serial key, in the meantime does anyone have any ideas on how to get round this?

Many Thanks

Thanks.

I have e-mailed Ahead and explained to them what has happened, I don't mind paying for a key, but I would rather not have had the hassle of installing etc., to find that it would not work.

Bought a full working version of Nero and it works fine except with the CD-RWs as mentioned above.

On my PC and others I have tested them on they show as full, there is no free space left at all. When I try to use them without Nero, for example like a floppy disk, I get the message asking me to insert a disk into drive D. I know there is a disk there because I put it there. If I try to use IN-CD I get a similar message. However one of the IT technicians at work put some stuff on one of them for me and said he had no problems.

I have no problems with CD-R and according to the update for my drive it is all updated.

Can anyone help on this. The disks cannot go back to the shop as it is well over six months since I purchased them and I would hate to lose money. I have e-mailed TDK twice now and had no response.
