Writing Quality
We used Mitsui 80min 32x & 40x certified media burned many CDs at 32x
and 40x recording speeds with LiteOn LTR-40125S. We used Nero 5.5.8.2 as a CDR
software. The produced CDs were measured by DigitalDrives
and the results are illustrated in the following tables:

As it seems with 74min CDs, LiteOn LTR-40125S has some problems to keep the
writing quality high in the first 10 minutes. The drive makes a high peak at
around 5mins, which is worrying. The writing quality in the rest of the disc
seems very good. This problem was not noticed when writing 80min CDs, and the
average C1 error rate is low (0.4). Below is the C1 error rate graph when writing
74min CDs:

When writing at Mitsui 74min CDs the drive again has problems and produces
high C1 error rate in the first 10 minutes. With other media, even with Mitsui
16x the error rate is lower. Especially with Taiyo Yuden media, the C1 average
error rate is 0.2. The picture below comes from Mitsui 74min 32x certified:
With Imation 80min 32x CDs, the drive produced C2 (un-correctable) errors in
the end of the disc:
