I've seen that there are several posts about this problem around, but I haven't found a single one with the problem solved! So, if there's someone who REALLY knows about this: The laptop has Mats---a UJ-811 DVD drive. It all worked fine for more than a year. Now, it doesn't read or write any CDs (audio, data). It only reads and writes DVDs. I don't know about burning software installations/uninstallations on it, because I don't know the exact date when the CD reading function stopped working. After I insert a CD-ROM, nothing really happens. I go to Windows Explorer and double-click the CD-ROM drive icon. Then it says: "The request could not be performed because of an I/O device error." What does this mean? Please provide me some advice on things I should check/correct, starting from the easiest one. I would like to get an answer from someone who has solved this kind of a problem once.
