Ok, I think this subject has been brought up in multiple forums but the topics seem to be the issue of getting Windows to notice that it has a CDROM drive.

My problem is that, even though Windows can see my CDROM drive, my drive is doing a hokey job of reading discs.

Every time I want to run a CD-R or retail CD I have to play around in properties with auto start and then eject and reload the CD or refresh the drive's driver.

Even then it still doesn't do all that great of job reading from or running retail software that requires a lot of data to be installed properly from the disk.

I have the dreaded LiteOn LTR 482475 which has no driver updates whatsoever from Microsoft's or LiteOn's sites.

I'm not quite comfortable with flashing firmware or overclocking but I think if I can find a similar driver, I might be able to fix it.

My other choice was editing the registery and removing the upper and lower filters but would that help MY situation or is that tactic only for people who can't find their CDROM drive at all?

It won't hurt to remove the filters. If you're using XP, this will do the same thing: http://www.dougknox.com/xp/scripts_d...cd_dvd_fix.htm

Firmware updates are very easy and safe IF you close all other apps and do NOT reboot or shut down the PC during the flash.
Your problem is a very common sign of a failing drive.

Thanks for the info and the link. I've got all sorts of viruses and trojans on my pc so it does the reboot thing at the most coincidental times - meaning flashing might be a bit dangerous for me.

then you should likely clean up the PC before troubleshooting hardware.
