Although my problem is similar to others discussed here, it's a bit different. I have two disk drives on my Dell 8300. They play CDs and DVDs fine. But, when I put a blank CD-R or DVD+R into the drive, I get (on the E drive) E:\ is not accessible. Incorrect Error. Or, on the D drive, "Disk is not formatted. Disk might be corrupted or using a format that is not compatible. Can anyone help?
