Here is a quote from the CDRinfo website review below. They stated clearly that LiteOn 24x CDRW drives can't write below 8x speed. But spanner, you say you can. That is interesting. Well, perhaps they made a mistake in the review?
BTW, what are the reasons you are burning at those slower speeds? Inquiring minds want to know!
"Conclusion
Positive (+):
- Supports 20x and 24x writing (Z-CLV) speeds
- "Smart-BURN" anti-coaster technology
- Very Good data reading performance
- Very Good Seek times
- Very Good DAE ripping quality
- Very good packet reading/writing performance
- Supports DAO-RAW
- Can read/write SubChannel Data from Audio/Data tracks
- Can produce perfect SD2 backups!!!
- Supports CD-Text (reading/writing)
- Supports Overburning (up to 99mins)
- Supports Ultra-DMA 33 connection interface
- Very good behavior even with non-24x certified media (not even a single coaster!)
- Retail package contains Nero 5.5x
- Low noise when operating
- Low price (170$<=) compared to the competition
Negative (-):
- Low reading performance with HS-RW media (16x CLV)
- Low DAE ripping speed compared to the competition...
- Very bad CloneCD reading speeds
- Doesn't support lower recording speeds than 8X
- No cooling fan
LiteOn's attempt at the 24x writing speed is much more than satisfactory. The LTR-24102B seems to be the faster recorder, for now, and managed to outperform both Sanyo and TDK 24x drives in many reading/writing tests. The drive's overall performance was very good and -for sure- users will enjoy both 20x and 24x writing speeds. Other important features such as: support for SD2 protected discs, overburning (up to 99min) and reading/writing SubChannel data are present. Of course nothing is perfect and the drive needs improvement at the DAE ripping speed and when reading protected CDs. Also the drive doesn't support 1X, 2X, 4X recording speeds, which maybe be wanted from some users."
