Maybe your CMOS battery is on it's way out :lol:

I'm glad you got it working, though it's scary how much you can mess up with just one little tweak. I was messing around with disks at the weekend and my Maxtor (heap of crud that it was) was the only drive on the IDE bus and had it's jumper set to master. So I put in a Caviar and put it's jumper to master as well. On boot up it all worked but was very very slow in starting up. As I'd made other changes as well I went through everything changing this and that back and forth, until eventually I just removed the jumer and bingo, booted like a rocket! If it just hadn't worked at all I'd have done that before but the fact that it did work, but just slow threw me off the scent! That was a fun waste of three hours :evil:

For what it's worth:
I had a similar problem w/ a new HD.
Pulled the HD and ran drive fitness tester.
Turns out the drive was dying!

James:
There was all sorts of entries in /var/log/messages.
Nothing that would indicate a failing HD.
I was just thinking "what's new".
The Maxtor drive was about 2 hours old.
They sent me a re-furb.
But, I am still having issues with swap and purge.
I watched swap fill to 100% in about 1/2 hour.
The system then crashed for about 45 minutes
Since this is intended to be an un-tended system, I am running it on the bench and watching what happens when the "purge" command is run (85%).
So far: 1 crash, 1 peacefull pass.

I had a drive that progressively failed a few weeks ago. There were entries on the console indicating incomplete reads etc and bad checksums. It lasted a while longer but then gave up the ghost completely when I thrashed it a bit trying to duplicate it. I did the freezer trick with it which seemed to help a bit.

if you have some info on a drive and you want to recover it and you have tried everything else, stick it in the frezer for a bit, then once damn cold connect it back up hope it boots and get everything off it as soon as you can, works well for badly scratched cd's too

I would add that you should stick the HDD in an airtight plastic bag before you put it in otherwise it will (a) get all wet and (b) probably bond itself to the ice :lol:

update on this i have stripped the machine out and replaced it with an amd dualcore. On getting it home i noticed that the northbridge fan wasnt working. After a couple of hours 2 funny beeps come from it then everything slows to a crawl. I have replaced the fan (well placed one on top 4 now) and will leave it running in mocord mode at 100fps and see how it is in the morning
