Resolved Windows 7 showing incorrect DVD properties

Hi. I have Windows 7 64 bit. If I click on 'Computer' it shows a list of drives and folders on the left pane. On the right pane is a list of drives showing storage capacity. For example, my C: drive shows 816 GB free of 919GB. However, my E: drive (namely my DVD drive) is shown as having nothing on it, even though the DVD is half full. It is reading the drive because I can see the E: drive's folders on the left and when I click on the folders, lots of files are shown. If I look at drive properties, it too shows the disk as empty. Exactly the same thing happens with my F: drive (BD drive)

Does anyone know why this is ?

 

I had the same experience except That if I opened XP Mode on the same machine (Win 7's XP Mode) I could see the jpegs. This happened with the same disk on two seperate machines running Win &. I copied the Jpegs off of the disk in XP Mode and burned a copy very slowly and all machines in all modes could read the disk. I have no explanation for this. The drives would read, however, program install disks and DVD's, I have yet to try a commercial Movie, however.

 

I tried a commercial movie and it showed the correct disk capacity and use. Is must be the DVD+RW disks that I'm using. They tend to behave strangely. For example, they sometime show old home movie clips, even after I've formatted them. Oh well, thanks for your reply.
