How do I solve problems with my Liteonit CDRW drive?
It has been reported that it is not possible to upgrade the firmware of some 12 and 24 speed CD writers produced by a company called LiteOnIt. One user reports that this is due to problems when using the Highpoint controller. The solution is to ensure the CDRW is only connected to the VIA IDE controller and that the Windows boot disk is also connected to the VIA controller. If you normally boot from the Highpoint controller you will need to temporarily move the disk to the VIA IDE controller whilst performing the firmware update (although this is not possible if you use RAID). Otherwise, the solution is to perform the update on a different machine. Note that if the flashing fails you can jumper the CDRW to “LiteOn BOOT” and then the BIOS finds it and you can flash the CDRW to an old Firmware (LS17 is probably the last DOS Firmware updater) from DOS - see here.
Other problems with LiteOn drives, such as random ejects, are usually due to an insufficient power supply. Upgrade to at least 350W! Note however that LiteOnIt have released a firmware update http://www.liteonit.com/webfw/LTR-24102B/USER/R245S57.zip with the following description: “Solve the issue that part of CD-RW drives will always tray-eject after power on the PC with certain brands of motherboards due to its power supply is not 0 volt when power-off”
