Hi Ivo Sorry for being away for the last week and thank you all for your time and > patience! > Today I tried to collect newer log file than one attached in my first post. > I used the same HDD with no modifications of config or OS, on the same > computer with the same interface cable (original MGE, not hand-made).

I can test them with NUT. > > Sorry for (maybe) false allarm. > not a false alarm at all, since you had an actual issue! I'll follow-up in my answer to Martin. cheers, Arnaud -- Network UPS Tools (NUT) Project Leader - http://www.networkupstools.org Debian Developer - http://www.debian.org Free Software Developer - http://arnaud.quette.fr
