device timeouts on hard disks no matter what..

Hi all,

I started to got these device timeouts while writing or reading
hard disks. I thought it was my cheap Mini-ITX motherboard that
was too slow or something, but now that I have changed everything
else than NetBSD, and I just got this, basically without any
load on the server:

wd1a: device timeout reading fsbn 301867968 of 301867968-301868095 (wd1 bn 
301868031; cn 299472 tn 4 sn 3), retrying
ahcisata1 port 1: device present, speed: 3.0Gb/s
wd1: soft error (corrected)
wd1a: device timeout reading fsbn 521875008 of 521875008-521875135 (wd1 bn 
521875071; cn 517733 tn 3 sn 18), retrying
ahcisata1 port 1: device present, speed: 3.0Gb/s
wd1: soft error (corrected)

I emphasize that I have first changed disks, then motherboard, cables,
chassis, and the rest, except the operating system.

Why are these errors there? Do you get them? Is it certain that it is
a hardware problem or would there be something to be done in the NetBSD
code? Do all operating systems get those but they simply don't
print anything into their logs??

BR,
