ACER CD/RW drive constantly can't read blank media or says drive not ready
flightsim1 Feb-26-02 08:10 PM
My ACER CD/RW drive has been giving me fits lately. Whenever I try to backup or copy a CD it says the drive is not ready and can't read that I have a new blank disk in the drive ready to go. Sometimes if I reboot several times it MAY recognize that I have media in the drive, but more than likely it doesn't. If I put a written CD in the drive it can read it fine...what gives? I've tried several CD copy programs (Nero, Cd Clone, etc) and I still get the same message...drive not ready or no media inserted. I also have an ACER DVD drive and I have switched both drives cables and tried running the CD/RW alone..same problem. I've tried different media too thinking it didn't like the brand CD's I had...no good. Windows show a perfectly good drive letter and that it is working fine too. Any ideas?

If you are sure the media is good and the drive and software are installed correctly, try the drive in another computer to isolate the problem to the drive itself or the computer? Larry

Given the information you have given it is likely that the drive needs to be cleaned. (I mean the Laser lens)
A blank disk is not really blank!!
There IS info on the disk wich contain data of the capacety and a pre-written Guidance Track.
A written CD contains much more contrast in reflections than a blank CD.
Therefore a dirty Laserlens meight be able to read standard and recorded disks, while unrecorded disks are unreadable.

I have found that CD drive cleaning kits don't usually work. I understand they can actually damage some drives, but that was a long time ago. Have you found one that works? Larry

No, i am sorry.
Some of my CD-Rom drives were damaged as well.
I do it myself now.
I opens the drive and clean the lens with 96% Isoprpoyl (Alcohol) and a cotton tip.
Afcourse you should do it VERY carefully!
After that IMEDEATELY clean again with a NEW and dry cottin tip.
Close the drive and try if ithas improoved.

No, not that way! You will never rech the laser unit beceause it is behind de Spindle.

I remove the entire casing of the unit, and do the cleaning as discribed earlier.
Then i replaces the casing and rebuild it into the computer.

Thanks. I'll give that a try the next time I see the problem. That will of course void any warrantee. Larry

Yes, it WILL void warranty.
but, will warranty be worth it if the period has expired?
Mostly the problems will begin just after expiration!
If you do it gently and with very low pressure on the tip, it cannot fail.
The lens can really be moved around a bit without damaging it.
Vertical pressure is the most dangerous thing if applied to the lens.
