Most Reliabe Liteon 52327S Firmware?

Postby y2deep on Sun Aug 17, 2003 7:07 pm

Hi everyone.

I just bought a brand new computer and asked them to put in the LiteOn CDRW (52327S).

I was just wondering because i've been reading that the new drive had quality issues or wasn't as good as the 52246S in some regards. Have the firmwares addressed this.

If so, which firmware is the best for this drive that settles all the problems, because i've also been reading some of the newer ones have problems.

Thanks. Your help would be greratly appreciated.

I'd be interested to see what sort of problems the latest firmware has? I've only seen good comments.

I think the new QS08 is the best, but I might be wrong.

well for example a topic like this?
http://www.cdrlabs.com/phpBB/viewtopic. ... light=qs08

is that just a media thing. Has it been addressed?

By the way is there a QS09? I read one of your posts talking about it? but is it official?

I thought that QS09 was better than QS08, but I don't know for sure because because I can't test it because my 52327S is on backorder. :(

There is a QS09, get it from dhc014.rpc1.org. There is a link in the top right hand corner of the page. rdgrimes has done a few tests of this firmware, and he has found it to be the best currently available.

There is one potential change in the 08 and 09 firmware. Due to further adjustments in the laser calibration, some media is now causing the drive to slow the burn speed late in the burn. The result is a longer burn time than if you had chosen a slower burn speed. This is a drive-specific issue, just as it is with the 6S drives, some drives will behave differently than others. TY media is affected, as are others. It's the cost of increasing laser power in order to lower read eror rates.
One interesting note is that the 7S drive can downshift the burn speed without pausing, a very nifty trick. If you're not watching the speed indicator in Nero, or listening to the drive, you'll never know it happened.
But anyway, earlier firmware will give you higher measured read-error rates with faster speed on more media, later firmware will give you lower error rates and less speed. With RW media, the later fimmware gives the best quality.

Thanks, that really helps a lot. I'll get the QS09 firmware. How much of a slow down by the way. something insignificant?

Thanks

The slow down will be completely drive-specific, and is also related to things like case temp, drive temp, and media. With a cool drive, I don't usually see it. I saw one report of a drive doing it on TY at only 50%, which is a significant slow-down. But setting the burn speed at 40x will avoid it and result in a faster time. My 6S drive has always done this on TY.
