Dear folks, Laptop met teac-dw-224e combo drive (burns CD's only, no DVD's), XP home. Situation A: I have no special burning software, I use standard XP features. CD & DVD's ready bought, or burned by others are working just fine. Burning of CD's doesn't work as XP doesn't recognize a blanc CD rw disc, CD drive makes jamming noise. Hardware seems to be fine. Situation B: After installation of NERO Oem all works fine for a few weeks, as well as burning of CD's.Today's situation: blanc CD rw's are recognised, burning process with Nero seems to be normal, but afterwards the freshly burned CD is not recognised, both Nero & My Computer (in which I tried to open the CD) get frozen and need to be closed with CTRL+ALT+DEL. CD drive makes jamming noise. Hardware seems to be fine. The same problem as in situation A, except: Nero recognises blanc CD rw's, burning process seems to work fine, but the freshly burned CD is not recognised. I tried many brand discs, all the same! Who can help me? Thanks, Max.
