I've got a P1.8, 512MB, 2 WD 80gig drives (BB). In my quest to improve my DVD burns, I decided to defrag my D drive based on all the suggestions I got. I bought a copy of Perfect Disk and ran it using the Smart option and now the drive has slowed down tremendously. All files are defragged and I have an 8gig contiguous free space, but now I have massive buffer underruns when burning and avg maybe 1.5-2x speeds for a DVD, taking about 35 min per burn.
I ran Norton Disk Doctor and Scandisc and found no errors on the drive. Also did a virus/spyware check and have none. One night I let the defrag run, the next morning I wake up and the performance is terrible. I mean, extracting a 700MB RAR file that used to take maybe 2 min, now takes 8-9.
Anyone have any idea what could be the problem?
