If it's not burning properly, then it is probably broken, for whatever reason. It should last for way more than 100 burns, but these things do sometimes just fail unexpectedly and for no visible reason. Next time, keep the computer somewhere less hairy, and maybe the drive will last longer!
I have a dvd burner that I have used for a bout 100 dvd's. There are times eately that the dvds do notbuirn well and pioxel up the stop. I think it is from my black labs hair getting in. It gets everywhere. When we dust you could make a new dog from all the hair. How can I clean this drive or I am I deluding myself and just need to pop for a new one? Hpow many burns is a drive good for anyhow?
