It's a Yamaha CRW-F1E CD-R/RW burner. Bought it three years ago. My motherboard's BIOS is able to recognize the drive; Windows XP recognizes the drive as well, and I can even use Nero to make backups of my documents and data files (end of semester approaching so I wanted to back up my stuff in case something happens during exam period). Nero even reports that the burn was completed successfully. But when I try to access the drive from either Windows Explorer or plain DOS prompt in order to check the contents of the disc, nothing happens. It's as if there is no disc in the drive even though I just loaded the disc. Same thing with normal CDs like an audio CD or any software installation disc. The drive will not read it. Had to ask my room mate to check the discs on his laptop, and they are okay. So it's a problem with my CD burner. It's the only CD drive installed on my system, so now I figure I have to buy a new drive, prob. one of the newer DVD burners. But it's the first time I ever heard of a drive being able to write to blank discs but being unable to read them!
