I did miss that step, didn't I? Sorry! Here are all the smartctl -a outputs: http://l-i-e.com/ad0.txt http://l-i-e.com/ad1.txt http://l-i-e.com/ad2.txt http://l-i-e.com/ad3.txt ad3 is giving the most errors... ad1 gives a fair amount though And the ad0 and ad2 seem to be giving the spinup errors. ad0 is pretty much full ad1 is the one I'm filling up currently ad2 and ad3 have no actual content on them yet, but will "soon" All the drives are kind of in an old PC tower (XT? AT???), except the outer casing is, errr, not there... Just the framework. ad2 and ad3 are in one of these Thermaltake iCage things: http://www.performance-pcs.com/catalog/index.php?main_page=product_info&cPath=257&products_id=3533 which converts the old-school floppy drive[s] bay into an IDE bay, and puts a big honking fan blowing on them. I'm not claiming it's "good enough" but I tried. I left the iCage "bay" between them empty for airflow/cooling. ad0 and ad1 are in the usual IDE bay of a tower. I have a fan in there, but without the cover to shape the airflow, perhaps that is not doing much useful... I can touch the exposed front and back top (above IDE cable) and lay my finger along it. It's "hot" but not like, "ouch hot" :-) I don't think it's 100C+ hot, as that's boiling -- but perhaps the thermometer is somewhere inside or... Seems more likely, though, that that number is Fahrenheit (sp?) and not Celcius.. I didn't even realize it said C, and thought it was F... Still seemed pretty dang hot to me. I could haul in the outer casing and slap it on though, if needed. I think. That big ol' fan might make that kinda hard. Oh well. I've got tin-snips somewhere around here... :-v > > Oh, here's a rather long excerpt of the log in case there's minutae > > within it that I've failed to include: > > http://l-i-e.com/smartd.log > > The output of smartctl -a for one or two of your drives would likely > be > much more indicative.

I am definitely not a hardware guy, as you have probably already surmised. :-) -- Some people have a "gift" link here. Know what I want? I want you to buy a CD from some starving artist. http://cdbaby.com/browse/from/lynch Yeah, I get a buck. So?
