LG GGW-H20L not recognizing BD-RE

[Salt]

Hi,

I have newly purchased a new PC with Vista 64-bit, and it came with an LG GGW-H20L blu-ray burner, and already I have problems.

The burner came with an LG BD-RE disc (25 GB). I finished editing a home video, and wanted to burn it to this disc. The movie is about 7 MB.

When burning (in Sony Architect), I first got a message that the burning was successful - after about 3 seconds. Clearly; it was not successful, and the disc contained nothing.

I tried a different software for burning (Nero 9), but then I got a message saying there was not enough space on the disc! But the disc is empty, and brand new!

I tried formatting it, but Windows could not do it. I tried looking at the properties of the disc, and windows tells me:

Used space: 0 byte
Free space 0 byte

What the h**l is going on?
