I recently installed the LiteOn 40x cd-rw (latest FW) and have been having both reading AND writing problems. I am running a Pentium III 800mhz system with 768mb ram, WinMe, and have experienced these problems with multiple software apps, including the latest versions of Nero, MusicMatch, EZcd 5, CloneCD, etc... And I have also made attempts at every IDE position possible (as a Master to another CD-ROM drv, as a slave, and all by itself, in both IDE slots on the motherboard).
Here's the situation...
In attempting to burn audio or data to media marked as 32x compatible (including TDK, Memorex, and Maxell) all is fine when I burn at speeds of 16x or less - very smooth, no problems. However, when I try to burn at the media's advertised speed of 32x, about 30% of the way through the burn I begin to hear the drive spin down, and up, and down... for as long as a minute, with no further writing (as if it's stuck), and then either my system locks up, forcing me to reboot, or the application returns a "Device Error, Burn Failed" message.
For a drive marked as 48x reading, the LiteOn seems a lot slower and less stable than my 24x cd-rom when installing programs, copying files, or even accessing the drive in Explorer to see what's on a disc. But my biggest problem has been playing media directly from the cd. Whether it's mp3, mpg, or an audio disc, the drive spins down to a stop and then spins up again nearly every 10 to 15 seconds, causing a few seconds of silence or skipping... all with media that plays absolutely fine in my other drive.
I've tried everything from toggling the DMA and smartburn to taking every other drive out of my computer in hopes of finding a technical conflict. Clearly, none of that has helped. I still encouter the same predictable problems. I'm just about ready to accept the fact that I have a deffective drive, but wanted to throw it out there to you all to see if maybe I'm missing something.
Thanks for taking the time to read this, and please let me know if you have any suggestions (or simmilar problems).
