Right heres the deal. I have a windows XP PC and its fast enough (i don't think this problem is related to the specs of my PC so i'll skip them). I have a lite-on 812@832s burner, and everything has been fine for a long time.
However recently i noticed two problems. One is that my burner will no longer burn DVDs in the correct way, the buffer just drops to zero, the light turns orange (hence is pauses burning) and the buffer fills up again and its off on its merry way (does this lots of times during one burn). CD's burn fine, everything reads fine. I've never had this problem before. The second problem happened about the same time (hence i think they are related) and it is that i have my xbox connected to my PC for FTP purposes. Its always been fine, ran at maximum speed but now at best it runs at 3mb/s, i have not changed anything and besides i'm not a dummy, i would know if i done something to it and how to fix it.
Heres what i think the problem is, i just want other opinions before i go shell out for a new burner. My hard drive has been quite full for most of its life, i have a 120gb unbranded 7200rpm IDE drive. Both of the above problems happened at the same time so i thought the hard drive couldn't sustain such "high" transfer rates in order to keep the buffer filled up or to transfer at 10mb/s. I've used defragmenters, one of them crashed when i done an optimised defrag, and other tell me my hard drive takes 1.5 times longer than it should to access files. When i do an ordinary defrag i get about 3% improvement. And by the way, windows takes an age to shut down, and i mean like 10 minutes, no joke.
Now is it the burner and the motherboard thats the issue or is it the hard drive? Sorry for the long post, cheers.
