Just tried to burn some HD backups last night, and kept getting an error saying that the Power Calibration Area was full, and that the drive couldn't write to the disc. I tried four or five blank CDs, all with the same result. I've been using this burner for a long time now, and the discs are off the same spindle that I've been using with no problems up until this point. Just wondering if this could be an issue with XP? I've tried this under Adaptec 5.0, as well as the latest version of Nero, and I'm using an HP 7200i CD writer (worked fine for four years now). Any ideas?
