Here is what I experience
1) The drive can read perfectly all types of cds
2) Using Nero CD/DVD speed I managed to complete perfectly the write test
3) I can erase any CD-RW media
4) When it comes to actually writing something on the cd Nero always fails on lead-in. In fact it writes nothing at all on the cd and the cd can be used again on my ASUS 52x\24x\52x CD-RW drive.
