    I have 2 discs which were burned using Windows-7 that were opening fine. Then, both discs refuse to be opened on 2 different computers (both using Windows-7). Both discs show that they have data on them but neither one will show any files. They were burned and ejected properly and both worked fine. Then, additional data was added and, again, both were ejected using the proper protocol. Now, neither disc will open!

    These discs were burned with the protocol of being like a flash drive.

    Anyone have any suggestions as to how to get these discs to open?

    Problem defused!

    Since I still had the information on one computer, I burned new discs. This time I burned a set using the "flash drive" properties and another set as "permanent". Both sets work fine. So, burned additional sets, using both protocols, as "backup".

    The blank DVDs, both the faulty discs and the new "good" discs, were from the same batch of Phillips DVD-R. Frankly, I don't have any idea as to what caused the failure of the first set.

    The bad disks. are not scratched on ether side?
    Were they by chance left some place where direct sunlight could strike them?

    Neither disc has any physical problems and both were laying beside the computer out in my main radio shack.

    I did try both in my "backup" computer (which also has Windows-7) and at least on that computer an error message that both discs were "damaged" appeared. The newer computers, one with Windows-7 32-bit and the other with Windows-7 64-bit, come up with a screen to "burn" files. The oldest computer also has Windows-7 32-bit. I do have a computer that is not hooked to anything, that has Windows Vista but did not try to use it.

    Both discs were burned using the Windows-7 32-bit computer at my main operating position.

    That is indeed a bit strange.

    It could be that they need to be finalized.

    If they were made so you could add more data, normally they only work on the original drive they were Created on until you close / finalized them (Write the TOC). Depends on the software used to create them.

    The Data is probably there. Just hiding from you.

    That is a very good point; I usually save up enough data to fill a disk, but when I don't I I make sure the disk has the root directory written and is closed.

    Both discs went through the "finalization" procedure which happens when the "eject" is "clicked upon". I tried putting both back in the drive seeing if this was the problem. However, the only thing that happens is that the screen for adding more files comes up. I tried adding another file and then the computer wants to reformat the disk.

    As such, since I still had all of the data on the computer I just burned some new discs. However, as each disc was finalized, I removed it from the drive and then reinserted it in the drive to see if it will open properly. That worked fine.

    To avoid losing the data again, I burned the data to discs both formatted as a "flash" drive and formatted as a "permanent" record.

    I'm confused. I thought you said in your original post that you added more data to the disks at a later time. If the disks were really finalized (or closed), it would have been impossible to add any more data to them.

    Very True.
