CDs are used for storage but executable files can be ran from them - all you programs are loaded via the CD/DVD. Yes, all files burned to CD become read only and if you copy any back to your hard drive you will need to change the name if you intend to modify the file. I know nothing about re-writable CDs but I would suggest you erase everything when wiping it. Do not apologise for asking seemingly basic questions, asking is learning.

I found this at WorldStart which appeared in their Newsletter and it worked for me. I thought I would share it with others in case they have a similar problem. I quote: "Other Eject Options" I'm sure many of you have read our tips on how to eject a stuck CD from your computer, but even after going through all those steps, are you still having trouble getting that stubborn CD to come out? Sometimes those things can be so frustrating and after you mess with it for awhile, you probably just feel like throwing your whole computer out the window. Am I right? Well, before you go that far, give these alternative tricks a try. They may be just what you've been waiting for! First, try adding something to the CD. If you put an extra file or another song on it, that might be enough to coax it out. Also, when you're using a CD, make sure you eject it before you start up another program. If you leave the CD in its tray while you use other programs, it could cause some problems. Another thing to try is a simple reboot. Sometimes when you shut down your computer and then turn it back on, the CD will eject. Now, while all of those are good suggestions, they still might not work for you. So, if that's the case, you may want to try the other tips I mentioned in the first paragraph. One of them tells you to try the traditional method of right clicking on your CD drive and choosing Eject. I know that's the problem you're having, but if you try it more than once, it could finally open. You never know! The other tip we have tells you how to use a paperclip to get your CD out. You can read all about that here. Either way you go, I hope you're finally able to get your CD out so that you can enjoy your life in happy CD bliss once again!" end of quote.... IT WORKED FOR ME. Also, I bought a Laser Lens Cleaner for my CD-R, CD-RW, CD-ROM and DVD....and they are now cleaned.

RW type disks, whether it be CD or DVD, should only be used for short term storage. Either type disks will let you transfer files to a different computer. If you use the RW type disks you can edit the files on the disks. If you use the R type disks you can copy the files to a computer, then edit the files, and then put them on another disk, R or RW. RW type disks are not a reliable storage media. If you are just moving a file from one computer to another you shouldn't delete the original until until the copy is safely on the other computer. If you are just wanting to back up files on your computer, use the R type disks and make a new copy periodically. If you have a small number of files to back up consider using a web service to store them or get a USB jump drive. (very handy to have). Whatever backup solution you choose remember, it won't work if you don't use it. Pooh Bear

When you insert your CD I assume the activity light on the DVD player is activated for a few seconds? Your DVD would undoubtedly have the auto start feature where your photo CDs would not. So try right click on Start, click Explore in the pop up. Now look down the left side for your CD/DVD player and click on that to highlight. Hopefully all your photos or folders on that CD will now appear in the right side of your screen.
