Re: A USB HDD is trouble outbreak in debian7.7
GLANTANK is a gigabit version of LANTANK. IO-DATA's child company
Chousensha (Challenger) produced these in response to the Kurobako
(with which some here may be familiar).
These are customizable NAS units, apparently running a customized
debian (MAKAI -- MAKe Again ISO Image) internally.
LANTANK had an SH4 cpu, but the GLANTANK has an ARM (XScale).

The summary here is that the GLANTANK seems not to like the
SYNCHRONIZE CACHE command.
話をまとめると GLANTANK が SYNCHRONIZE CACHE の命令に応じないようです。
Alan Stern says that the kernel should be able to handle this in 3.18
or later, but Jun indicates that 3.18 does not handle it yet.
スターン氏によると、カーネルの 3.18 なら対処できるであろう、ということでした。その反面、 JunItou の結果はそうではなかった。

I'm thinking that the best place to fix this would be in the MAKAI
community, but, as I check back in the Japanese list from last month,
it looks like Jun has already tried contacting them. And that
community seems to be an abandoned sourceforge.jp project, completely
untouched since 2010. And the Makai project doesn't seem to have a
place to post bugs.
it appears that last month I seem to have found something that made it
look to me like the once-maintainer of MAKAI, kin-neko, has
more-or-less washed his hands of a ten-year-old project that never
developed a self-sustaining community. I don't remember where I found

Anybody here in user, arm, or embedded (or d-japanese) have a suggestion?
Be careful when you look at conspiracy.
Look first in your own heart,
and ask yourself if you are not your own worst enemy.
Arm yourself with knowledge of yourself, as well.
