According to Plextor's specs, this drive can burn CD-R at 1x, 4x, 8x, and 12x. It doesn't do 2x to CD-R media, only to CD-RW. 80-minute blanks have poorer reliability and compatibility than 74-minute blanks, because they push right up against the lower spacing limit of the Red Book spec. You'll get more reliable burns, with any drive, if you use 74-minute blanks. That being said, I've had extremely good results with all media I've tried (74- and 80-minute) in my 12/10/32S drive. Even some no-name 80-minute blanks I got for free (via a rebate program) burn perfectly at 12x. I've been told that modern media often work better at higher burn speeds than at lower speeds - the dye is optimized for a short laser exposure. Burning at 4x might work better than 1x in your case. I'm not sure what you mean by "medical grade" - I've never seen discs described that way, and have no idea what sort of testing or certification is being done to them to justify this terminology. What brand are they? If you do a "cdrecord -atip" with a blank disc in the drive, what does it report re the vendor, etc.? You might also want to check to see if the drive is fastened down properly into its mounting bracket, and see if there are any sources of vibration (e.g. fast hard drives, etc.) which might be shaking the drive around. Burners usually need to be kept physically stable during a burn, to keep the beam from being jolted out of the groove. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
