I bought an LG 16X External Super Multi DVD/CD Rewriter from PC World.

I wanted it to use DVD Ram discs.

After succesfully transfering a few files over I got an error message saying the disc might be full.

When I checked properties it did indeed say the disc was full even though I had only transferred a couple of small files.

I took the drive back to PC World and they replaced it.

After using the new one with no problems for a week the same thing has started to happen.

Is it likely that 2 drives would have exactly the same fault or is the error with my computer ??
