LG GSA-5120D External USB DVD Burner and error messages

[zillah]

I tried to use LG GSA-5120D External USB DVD Burner that I borrowed from my friend,I hooked to the Desktop Win2003 SP2, I have 3 different images on the HDs (not only one, if it is one image we might be think the problem with that image itself ) and I have used two different softwares for burning these images, Nero7 and MagicISO.

The process of burning was ok, but when it came to play thes DVDs I received this message :

Windows cannot read from this disk.The disk might be corrupted, or it could be using a format that is not compatible with Windows.

and with other DVD, I received this error :

F:\ is not accessible,,,,,letter F for the DVD
The files or directory is corrupted and unreadable.

I did a test , I brought a DVD that is already burned and play with GSA-5120D, it worked.

The DVD barnd that I am using are : Imation, LG

I updated firmware from A102 to A104

There was only one option for the speed which was 5500
