Very strange...I turned off the system and swapped an sata cable with the hdd that was giving me trouble and restarted the system to my main hdd (the one giving me trouble). I stayed on it for maybe an half hour and no warnings were given.

I then swapped the cable back to the original cable and rebooted to the main hdd of trouble and have been on it for close to an hour now maybe and no warnings.

So it seems it wasn't the cable (you guys probably already knew that but it didn't hurt to test it, heh).

The only option left that makes any sense then is what H_TeXMeX_H was saying about some software somewhere. Surely nothing I've installed like an app, but something in the 'system' stuff is all I can think of (and I'm not anywhere near as knowledgeable as you guys about this stuff!), or maybe, just maybe it *is* a heat problem, since I happen to have kept the side panel off the case during my cable swap testing. I'll see if I can install lmsensors and see if that shows me anything, and/or just play with the side panel off and on for a while each way to see if that does anything.

I honestly appreciate the help you guys are giving.

1. hard drive is more than 4 years old. May not be the cause.
2. Bad PSU. Generally, PSU should be twice of total wattage of all components.
3. Electromagnetic/Neutron Interference.

PSU is a good one and less than a year old. It's a nice one with a good deal more than twice what I actually need (XFX 450 Watt Core Ed. Full Wired 80 + Bronze PSU).

As for #3...maybe crossed wires from something like a case fan over the sata cable or touching the MoBo somewhere perhaps? I mean it works with car and truck motors where you hear the sparks in the spark-plug wires through the radio if they're not grounded correctly or are cheapo wires.

Either way, it seems to be solved. Been on my main hdd since last reporting and no problems whatsoever.

(btw, that Paul Johnson (whoever that is) sounds like a brow-beaten mama's boy whose ol' lady wears the pants and has a bigger set than he, lol. Does he also mean it's okay for him to 'talk down' to the uneducated with words they don't understand? I know, I know...it's just a sig, but I had to say something about that one, heh heh)

you cannot be sure, it is good one, even you bought it yesterday from shop, until you see that all lines throught oscillograph under a load.
i speak very seriously. i have see many of cases with very different symptoms, who in final is getting from PSU. PSU is veru important piece in modern computers, and its problems usually not can be see with eyes, and in many cases even throuht cheap "psu testers" or voltage monitoring via motherboard built in monitors...

Oh yes, I know about the importance of a PSU and of getting good from cheap. In the years I've been using computers I've had two PSU's actually blow up on me. Each time it was a very loud 'POP' (about like a Colt .45 automatic) and some smoke rising up from the tower. Luckily I was there when it happened each time, though there was no fire, if there *had* been I could have put it out quickly and easily.

In this case though, I don't think it's the PSU no matter what, as I said that the secondary hdd worked just fine with no warning pop-up windows or anything else for that mtter and now too the primary hdd is working fine too.

It's very, very strange though, because I can't seem to find anything about it ever happening to anyone else and can only agree that it was some kind of software messing up somewhere during boot or something (though I didn't see anything strange in dmsg either).

Just want to show a sample of some of the syslog error windows that pop up at random times but if I were to guess, maybe close to three or four minutes apart when the windows suddenly pop up.. This is just a sample. There's usually quite a few more 'below' the screen that I have to click on to get rid of, and of course the errors aren't only what you see here, but there are others. I've done a warranty registration with AMD to get another CPU as I think this one is bad.
