It used to take me about 2:35 to burn a whole disk. Now no matter what software I use (and I am using the same media, and have tried others) the burn will reach 50X or so at about 80% of the way into the burn, then slow down to about 24X. The burn takes about 3:10 instead of 2:25 like it used to. I have defragged the hard disk, changed IDE drivers (yes, the drive is in DMA mode), etc., etc., all to no avail. The occasional disk will still burn at full speed and finish in just over 2 1/2 minutes, but there seems to be no consistency. I used to have ALL my full CDs finish in that time. I have talked to Plextor tech support, and they think the drive is fine, that this is an IDE driver problem, but changing those drivers did not help. Any help would be appreciated.
