I see. Thank you for telling me that. I understand it is
RAIDframe way. Knowing it is better than nothing.
It's little bad for me since current FT100 IDE driver is not
stable under some "going wrong" condition. It's sensitive
and causes unrecoverable error if the situation is going
bad. I like this driver and appreciate to the author
though. Maybe I should put some syslog checker into my
crontab to check those wd error messages as soon as

There are tons of DMA error and correction messages for
both. I should notice them, but I didn't. Then, system was
crashed. For the people who have an interest, check below.
It's contains all hard disk related messages starting from
one day before the crash day.

I've been using this machine several months in the same
configuration. This machine had been on from June 10 when
it was crashed. I think this is caused by heat, since I
don't have air conditioner here and these days, it's hot.
I'm using HDD coolers to keep them as cool as possible
On the other hand, I remember the same situation I
experienced when one hard drive was running out. It showed
DMA error sometimes, then showed it often, and finally gone.

There was no panic message as far as I remember. It crashed

Yes. I'll send them later. Thanks.
