Tony,

I tend to agree with you, but I wonder then how it is possible that the disk worked fine for 13hrs straight uploading, and then all of a sudden started showing this behaviour. (after being +/- 80% full). And from that moment on every single time in the first 15 minutes.
That's why I would like to know if there's a way to perform a stress test on this HD.
Is it possible that a HD starts showing heat related problems after a period of usage??

I might also try to open the player up again tomorrow and remove that 48gig, only using the 10gig (like it was). Normally that 10gig shouldn't have any problems with uploads. If the problems don't turn up in the first 30 minutes then I'll know for sure.
There is no way that incorrect formatting or adding of directories could make the harddisk work ok for about 80% and then start showing problems?
All I did after all was format the music partition and add two directories, but I don't remember which they were - PGrzelak advised me and I can't remember which they were. But I would think that if the disk works for 80%, it should work 100%!

Bonzi,

I've enabled the HD led, and I'll see what happens now. Because of the command you provided I've been able to see that the second disk has not been used yet. All files so far have been put on the first hd. I will try what you suggest today, and see what it does. I suspect that I will do exactly what you say it will do : the problem will show up faster, probably even in the very first transers.

I will contact tech support tomorrow, and see what they say. I haven't done so yet, because I figured I'd see what the people on the board had to say about it first.
