CD Burner issue

I still have this annoying problem with my LG burner. I mostly use Maxell's 700 mb cd-r's. I can burn a disc and read data off of it just fine, put it away for a week or two or more, take it out and put it in, and I can't access it at all, or I can access some files but not all. Especially large files. What the heck could be causing this? Then at times the drive just ends up in this "condition" where regardless of what cd I put in the drive it will say the disc is "bad media" until I reboot, after which it'll work again.

Do you know of any software I could use to perform really exhaustive tests on the burner to perhaps find out if this is a software problem, or hardware problem? And would that even help?

It could be that your drive is bad. Try burning at a lower speed to see if it helps out at all.
