Really poor FileServer

[thavinci]

Well i don't know the model of the 500w either. It is the only stuff the distrubuters have over here..

But i can't see how it can still be a problem....

Looks like i havent had any issues with the one drive since the replacement (ad6).

However ad2 still permanantly has issues while copying to it...

However this has not crashed server yet and data seems to be intact.
The issue with ad6 caused hangs and eventually a reboot on server.

What is the explanation of the errors i was receiving on ad6 and the ones im getting on ad2?

And is it safe to simply ignore these errors?
