Do CD-RW drives have a limited number of burns? A couple of computer science majors at my old school told me this and I didn't really beleive it. However, my HP CD-RW has stopped writing discs (but still reads fine). I've had it since the summer of 2000 but granted it's 4 years old, I haven't really pushed it hard. I use it to read CD-ROMS and play music CDs occasionally, and have probably burned a couple-dozen music CDs. Is it kaput, in need of cleaning, or what?
