I've searched the forums on this, yes, so don't worry I've also had my hand at a few Google searches related to these codes but nothing new learned their either, so here goes: I was running 10.3.8 and burning with RiData 8x DVD+R blanks under Toast and everything was working well. It had been some time since I burned a DVD (although numerous CDs) and since then I've gone through 10.3.9 (which did work with these DVDs) and recently to 10.4.2 (and now .3) which until recently I hadn't burned a DVD with. So last night I figured it was time to back up a few files of images (also on a couple other drives, but nice on DVD sometimes) and I can't burn anything to DVD, files, movies, anything. I keep getting: The drive reported an error: Sense Key = HARDWARE ERROR Sense Code = 0x09, 0x01 TRACKING SERVO FAILURE and once ok'ed, followed by (sometimes): The drive reported an error: Sense Key = MEDIUM ERROR Sense Code = 0x0C WRITE ERROR So after reading on here and links through Google, some suggest it is a media-related issue (they worked fine before ) and others say it's a drive issue. Anyone here having or had anything like this? I purchased two cakeboxes of this media (100pk) when they were über-cheap on Newegg and I'm only halfway through on the first....so hopefully something can be done. Anyone know if Toast 7.0.2 fixes this?
