Now let's take a look at what Nero Infotool reports about this LiteOn drive:
Maximum read and write speed is detected as 52x, the drive supports C2 error report and the Mount Rainier format. Buffer underrun protection is of course also present. The buffersize of the LiteOn drive is 2 MB.
Smart-Burn
LiteOn's buffer underrun protection technology is, of course, included in the Smart-Burn technology. If the drive's (rather small) buffer of 2 MB runs empty, Smart-Burn allows to stop the recording process, wait until the buffer is filled again, and continue the recording process then. The gap caused by such an interruption is not supposed to cause trouble for any drive which reads such a disc. Unlike the Burnproof-feature which Plextor CD writers include, LiteOn's buffer underrun protection system is always active and cannot be switched off.
Smart-Burn has a second task, besides buffer underrun recovery: It is supposed to determine the best recording speed for any inserted media. This avoids coasters due to too fast recording.
Mount Rainier
"Packet writing" is an invention which allows a CD-RW (or DVD-RW) disc to be used exactly as if it were a large floppy disc. The goal of Mount Rainier is not only to add support for packet writing, but also to standardize packet writing. Former "packet writing systems" are not completely compatible to each other. A disc formatted with an old DirectCD version cannot be written with InCD, and vice versa. So these programs seem to do the same, but they do it in different ways. Mount Rainier is supposed to be a solution for this issue, and to guarranty interchangeability of discs. If you are interested in Mount Rainier, you might want to read a more thorough explanation of it.
Let's continue with a CloneCD screenshot:
As you can see, the drive supports RAW-SAO and RAW-DAO mode (RAW-DAO is needed to backup some copy protected games).
Next, we'll have a look at the data reading capabilities of this drive...
The Package
I'm just waiting for my LiteOn LTR-52246S to arrive. :4
In other things . igot the CMC media and no way i can even burn it at 24x .. It gives me coasters. i have to use 16x. For some odd reason. With some 24x media .. im able to go up to 48x.
BTW, i've got s07 firmware.

JamworkS
The writing quality with many media is very bad, i never buy a writer like this
