0 bytes shown drive properties after burning 52MB to DVD

I got my Toshiba M105-S322 as a refurb and tried to use the DVD "Super Multi Drive" (all formats) to burn a DVD for the first time yesterday.  I used ImgBurn to burn an ISO file that I downloaded (GParted) to a new DVD+RW disk.  The burn went fine, I can see the files on the disk in an Explorer window.  However, when I look at the drive properties it shows 52MB of used space and 0 bytes of free space.  What happened to the unused 4.6GB, more or less, that are on the DVD+RW disk?

Well strange...what kind of media are you using again?  brand?  part # ?  model #?  if there are such #'s or descriptions on the media...
You'll want to make sure you are buying RE-WRITEABLE media.....
otherwise the only other thing I can think of is you are closing the session or closing the disk.  If you close the disk, it makes the cd/dvd not able to write anymore info on it.

Is it a Rewriteable?  (the media that is...)

What it is is that the ISO is an IMAGE file....so it used up the whole disk because thats what the image is probably doing.  In order to reuse the RW....Assuming you mean RE-Writeable..., you would need to format the DVD and start over again.  A +RW drive only allows you to read and write many times.  However due to burning an Image it has closed the whole DVD.  If you were to just burn a file or files onto the DVD and not use an ISO or IMAGE or bin, etc....you should be able to write to it many times.  Here's some info for you to see:

Here's how DVD+rw's work...however does not tell you how to burn:

The problem doesn't seem related to the ISO burn.  I tried a test, copying a 1.16 MB PDF file to a new CD-R.  The file copy was successful and I can open the .pdf file from the CD.  However, the properties for the CD show 1.16 MB Used space and 0 bytes Free space.  I tried to copy and paste another file to the CD and got the error message "Cannot copy file.  Disk is write protected.  Remove write protection or use another disk".  I was logged into the administrator's account when I tried to copy the file to the CD, if that would make any difference.

Any idea what's going on?

I was wrong in my question - the media I was using was DVD-R, not DVD-RW.  Also I trolled the ImgBurn site and discovered that this software doesn't support multisession burns.  So, your second response nailed the problem.

Thanks for your help.

Great!  Glad you got it figured out! :)
Nero's a pretty good program if you want to give that one a shot!  I recomend it!
