I was using Brasero to burn a Win7 .iso for a friend (sorry, couldn't convince him to try Linux e.e) and when it was at 80% the process stopped with a "SCSI error on write(1248864, 16)". I burnt some DVDs a day or two ago and it worked perfectly, and I know for sure the error isn't caused by the .iso file. I'm using a DVD from a pack I bought today, they're Verbatim DVD+R, while the other day I was using DVD-R. My computer is pretty old but I changed the DVD burner a couple of years ago or so, and DVD+R are supposed to be compatible with more DVD players, so I can't guess where's the error.
I'm using Ubuntu 12.04. Any idea will be welcome. Thank you.
PS: And please, ask me for information in case you needed it.
