This will be one of two things, 1- a driver glitch, you will need to uninstall the drivers for the cd/dvd drive from the device manager, then reboot. The machine will find the drive and reinstall the drivers automatically. This will fix it if it's a driver problem. You can also try any updated driver utilities, or patches for the drive from Acer's support site. 2- the cd/dvd drive has failed and needs replaced. These are basically plug and play devices, they either work or they don't, so a majority of the time when the machine stops recognizing the drive, it's because the drive has malfunctioned. Unfortunately, these drives are considered sealed units and replacement parts aren't available.

The problem when a cd or dvd player cannot detect a disc even though one is there can be two distinct problems. The most common is that the laser reader diode or led lense as some call it needs to be cleaned. Usually a good cd lense cleaner that looks like a cd works, but if it is not turning at all to start it off, it won't work. That is the second problem that if the disc does not turn at all, then it will give the same message or error. To be sure you need to take the cover off with it unplugged so that you can see the lens pointing up towards the middle of where the disc would be. Use a q-tip dipped in isopropyl alcohol to clean the lens then with the dry side of the q-tip to dry off any excess that has not evaporated. This usually fixes over 90% of those types of problems. Let me know if I can help you in any other way.

SOURCE: I cannot run any CDs
These are typical symptoms of the drive itself having failed. Usually it starts off not wanting to burn dvd's then not wanting to read them. It can still read cd's at this point but eventually has problems with these as well. You may have seen errors or a lot of activity that also took longer to do the same thing and so on.
What happens is the drives read/write head gets out of alignment over time. DVD's need the most accuracy and fail first while the cd's are much more tolerant.
Unfortunately the only fix is replacement of the drive. The cost of the drive from a online laptop or parts place will be $50-$100. This is definitely something you can fix. You need to remove ONE screw, pull the drive out, and put the new one in and put that screw back in. The drive just pops in. Probably took longer to type this than it does to change the drive ;-]
Have a look online for the drive and keep an eye out for instructions on replacing it so you can see if you are comfortable doing it. Most places will have a pictorial guide and some have online videos. It really is simple so you can do it. If you do a search for laptop repair parts you will find several web sites. Just look for your model to find your drive. If you aren't find the contact button and email them. Most places are quite happy to help. Some places will have used drives while other will offer new parts for about the same price.
