Hi Aron,
From our field experiences and customers' feedbacks, all of them direct to
vibration and power issues.
The vibration could be caused by FANs not only by themselves.
You mentioned it could be the F/W issue.
If the environment does not meet the prerequisite, FW could not work
correctly.
Actually FW just reacts to the situations not it causes the issue.
Please check it out!!
Thank you,

I've now tried with both 90 and 120 for the timeout value, and the
problem still persists. It seems to happen when lots of small writes
are occuring, e.g. when installing something.

I really don't think the disks are vibrating, I don't see how they
could. One more thing I'm going to test is to use the legacy ATA power
connector instead of the SATA power connector. This was what I was
using before when I only had a single drive and no RAID controller.
Maybe my power supply is malfunctioning and not giving enough power on
the SATA power connectors.. but I doubt it.

Is there anything else that could cause this? Have you guys at Areca
tested the ARC-1200 with Raptors in RAID1?

:(

Regards,
Aron
