i just bought some cd-rw's but the software i'm using is kind of primitive. i'm using them to b/u my key files, which is about 500 to 600mb but it keeps on telling me i have don't have enough space even though it recognizes that it's a cd-rw in there. i completely checked the software and found the only switch but it still doen't work. i'm using "my cd" which came with my hp9150 8x4x32. i'm looking for better software. my nephew suggested "nero". he said it even copies some the real tough ones, i also saw adaptec's software seems to be popular. nero 5.5 is about $70 at my local comp usa, i don't my spending the money if it would be worth it. any suggestions?
