Can't open data files after burning DVD - invalid file formats.

I've burned several DVD's using this drive with no problems. On this one disc, I cannot open any of my files. They are listed in Explorer with the correct icons and the file sizes are > 0kb. There is data on this disc!! These are mostly Photoshop and JPG files. When I try to open a photoshop file for example, it takes the time to read from the DVD, but eventually I get an "invalild photoshop file format error"

I can even copy the files from the DVD to my desktop, still no luck.

I used an Iomega DVD +/-RW drive. I used the included HOTBurn software to create the data disc.

Any suggestions how to revocer these files?

Can you open this image files up in another program like MS Paint or even Internet Explorer?  So you could copy the files to your hard drive but still can't open it?  This is a long shot, but try copying it using the command prompt.  Go to Start->Run and type in command and hit OK.  Now type in

X:

where 'X' is the letter of your dvd burner and hit Enter.  Next type in:

copy X:\*.* C:

Again replace X with the letter of the burner.  Then for the second paratmeter, enter the path where you want to store it (ex: C:\Docume~1\your_username\Desktop that's if you are using XP).

I copied an image to my hard drive using DOS commands, and the image will not open in any program. I have several hundred TIF files and I've tried Photoshop, IE, Windows Image and Fax viewer, etc... It fails every time.

Any other ideas?

If you can open the orginal file , I can say the DVD is not properly burnt.
Otherwise, clean the downside of the DVD with soft cloth from inside to outside direction and try it on another machine (best with a new DVD drive).
I feel your files not fully copied to the HDD.
if the file fully copied, the Photoshop will certainly does its work.

callander is the man, conceptually - create a HD copy of your culprit DVD onto the harddrive as a disc image file and then mount that with one of the virtual DVD apps as a drive letter. i'm using daemon tools which is probably one of the better ones, at least it's free and it always worked for me.

if you can open your files from the image file/virtual disk you got them, otherwise your DVD is a coaster.
