I have recently bought 2 Maxtor Diamondmax 10 200GB 7200RPM S-ATA/150 harddrives and have now run into some problems.
The most obvious is that when I watch videofiles they are choppy. They stop for a second and then continue. This happens a couple of times a minute.
Yes I have all the right codecs installed, I have tried several different codecs, uninstalled and reinstalled all codecs and graphic card drives.
I then noticed that the problem only existed on one of the drives and I began to suspect the drives. I tested to
play a video file and also copy files between the drives. I noticed that the transfer speed at the same time as the movie "chopped" dropped to less than 1MB/s!
Then I tried HD Tune, a hardrive benchmark program, and got these results:
This is a benchmark of the problematic disk
This is a benchmark of the second disk that works fine
I have checked so that UDMA is not off, so that's not the problem. I've tested with Powermax, a diagnostic application from Maxtor and it showed no problem. Could it be the S-ATA controller that have problem with the transfer rate? If so, I don't have a clue how I can fix/update S-ATA controller-drives so if you think that's the problem, please explain how to do that
Also, if the "bad" drive is the "C:", then just the os can be acting as the interferance. This is why video edit systems have system drives and data drives... the System drive needs to act very differently, and cannot devote full resources to streaming data.
Partition or not - the drive heads still have to access that data on the Drive 0, vs the Drive 1 where they do not. You will never get the same speed and access times from Drive 0 and Drive 1...though they SHOULD be closer than what you are showing.
