Hi and thanks in advance,

My Mad Dog 16X3DVD9-8X drive will no longer read DVD's but it will still read CD's with no problem. I'm a grad student on an extremely limited budget and purchasing a new drive is not an option right now. My school materials are backed up to DVD so I need to have access to them.

Couple of questions:

Are there separate lenses for CD and DVD? Could this somehow be a dirty lens that allows CD's to be read but not DVD's?

Is it possible to take an internal drive apart and clean the lenses manually? I've never done this before but if it's do-able I will certainly try.

I've called the local repair shop to see if they have an old drive they removed from another computer that they could sell for a few bucks. They've helped me out in the past but unfortunately they don't have anything right now.

Any help would be appreciated.

If it is dirty it will usually read some times but not others. Also, there are different color laser out there that read different colored DVDs so your drive might not be able to read the DVD because it is a new format.

As for the fix. get a new drive they are less than $50.00 and I am sure you spend more than that on lunch for a week.

Thanks for the reply. I'll try cleaning the lens since a new drive is out of the question. Fifty bucks is my entire food budget for two weeks! LOL. I just need to keep this old machine going until I graduate next semester. It used to read DVD's fine, in fact I burned these discs using this drive. No recent hardware changes or software issues. If cleaning fails I'll start looking around for an old clunker I can scavenge for parts or maybe borrow someone's laptop to read the discs and transfer the data onto my machine.

Just wanted to follow-up and say the issue has been resolved. I took the drive apart, which was much easier than I expected, and gently cleaned the lens with alcohol and a q-tip. Works perfectly again!
