It should be stable enough to install new drivers. At times it runs for 6+ hours without a problem.
I was reading in another forum that people are seeing bad SATA cables (and one of the posts explicitly referred to the ones that came with ASUS boards). The event viewer doesn't seem to give me any clue as to which drive (if any specific one) is giving me problems.
Does it make sense to spend a few dollars on 4 new cables? Or is this not likely a cable issue? I'm also concerned that even if it is a cable issue, that swapping 4 new cables in might have me swapping in 3 good ones and one bad one.
