</div>Thanks Garrett,<br>
<br>
memtest86+ had been run prior to updating BIOS. No issues.<br>
<br>
Boot drive is a Barracuda 7200.12 500GB, recording space is a pair of Barracuda 7200.12 1TB. They were all thoroughly tested using a certify process that ran over 12 hours for the 500GB, and 19 hours for the 1TBs. I use this process to weed out drives before taking the time to install them in a machine.<br>
SMART shows no errors.<br>
<br>
It took a while to figure out how to download Hiren's Boot CD since there are no download links on that page. 8) It's superslow, but will try seatools once I've finished downloading.<br>

The gui disk managment utility gives good smart tools reports, you can see the drive temp. but just in passing, I note you have 3 hard drives. We have a server that did random lock ups and I replaced every single item of hardware within (January this year), untill the whole thing was a new system apart from ubuntu 8.04.4 OS.<br>
I ended up modding the case slightly to put a big 120mm fan right in front of the bank of 4 hard drives to keep them cool. Problem solved. It never skipped a beat since then. I'd spent hours before then, sweated over restoring databases that had corrupted in the reboots/lockups or segfaults (I can't really remember which errors) and a quick replacement of the MB/CPU/RAM confirmed it wasn't them. (I kept the new dual core setup, only cost me about $380 all up) - Had already put a big new PS in.<br>
<br>Lesson learned: Extraction of the heat was not enough, CPU core temp did not tell the whole story. Cool the drives.<br></div></div><br><div style="text-align: left;">Barry Clearwater<br><div style="margin-left: 40px;">
