Hi Clifton,

I don't recall exactly anymore, but at least 3 cables have been used
without problems on other systems. I'm wondering, the mainboard acts
weird sometimes as well: when I press the reset button, it sometimes powers down.
Also, I just did a reset after it deadlocked on shutdown because of the errors,
and when the system booted, 2 disks were not seen by the bios.
I had to power down the box and when it came up again, the disks were back.
Can software leave the disks in a state that the bios doesn't detect
them after pressing the reset button?
I'm 100% certain that on my previous installation, in a 100% different
system, I got the same errors. That should normally mean either software or disk.
The disk has been replaced, the OS is the same. I'm either having really bad luck or something else is wrong.
What is a good way of stress testing disks?
Thanks!

- Remco
