Subject: RE: System / libata IDE controller woes (long)

Hi There!
	Yea, I thought that it might be power related as well, so I moved
1/2 of the drives from the 500 Watt power supply onto a separate one, and it
did not change any of the symptoms.  So I think that it's been ruled out.

	Thanks,
		Erik.
