Got a Coolermaster GXLite 500W. According to their calcs, 420W should be enough, but it's "only" got 6 SATA plugs. So let's see what happens when I tear the box apart tomorrow. Need to re-tighten the elastic anyway (the disks are *all* suspended) and then I won't put the new 2TB in the array. So it will be just 1 + 1 + 1 + 1 + 1.5, making around 3.7TB net. That's enough to be going on with (it'll be pretty full, mind...)
Deduplication will *not* be turned on this time. Atime will be turned off. The rest? Let's see how the performance goes for the short term. I need stability first and performance second, 60MB/s is fine, thanks.

PSU?!
So, the saga of the data that's not elsewhere continues.
I tried probably 15 times to boot the box yesterday, and every single time after ten minutes or so, it would lock up.
Then I set the PnP OS in the BIOS to "NO" and hey presto, it got better.
Removing one of the disks made it even better. So from here, it looks, smells and feels like there's a heat and PSU issue. I moved it back onto the table this morning (it locked up at 05:11) and in the process took down the NTFS disk attached (grr!) so I've started the copy *again*. If this works, then I'm 99% sure I need a new PSU as the old one seems to struggle under load and again under heat. It's pretty boxed-in back there, so I could sort of understand this.
In the mean time, then, I'll try to re-copy the data for the umpteenth time (lost another NTFS disk yesterday, main file table corrupt so Windows 7 says "NO!") and if I get that fixed, I'll be a happy bunny.
Moral? Sort your backups out before it's too late....

verkkokauppa.com rocks!
teh 7200.11s in the previous post; they were remanufactured disks. Bought from verkkokauppa.com.
I had no receipt, but the original "packaging" (antistatic bags). I took them back.
No issues. No replacements, but the "money" back and I've added €40 to it and got an HD204UI. Nice. No requirements on their part - and their customer service is really rather good.
Now, if only they could sort the transport out to their store...

CHS0 / DRDY / ATA issues under Ubuntu
I've been messing with Ubuntu for a while now, but I'm slowly hitting a brick wall. I had some major problems yesterday with my server box, where two Seagate 7200.11s appear to have died, and so I'm trying to pull the last of the data off that I'm not 100% sure is elsewhere.
1.2TB of it.
That takes time. Now, the disks were running OK yesterday - but the box locked up as soon as I tried to access the Samba share at one point. At another, it was running fine with 45MB/s transfer rates... and now? Now it's running 15 locally to a disk that's on the SATA bus!
Anyways, I don't care if the 2011 directory is copied safely.
The reason I write this post; I appear to have been having major problems with the SATA bus, and changing the graphics card appears to have helped. I do not understand this 100%, but if it's the cure for the issue, I'm not really bothered.
I'll keep you updated...
the new ZFS, by the way, will have Dedup and atime disabled from the start and will probably have either five disks in a single vdev for around 3.5TB of space or maybe two three-disk vdevs. Haven't decided yet, need to do some research. The box "only" has 8GB of memory and 6 disks (potentially 7), and performance is supposed to be best with only five disks. Performance would be nice, but 60MB/s is enough.
Just hoping the data comes off cleanly and then I can work on getting it back on again.
The 7200.11s were giving me the above SATA issue; one of them would drop off the bus five minutes after boot and the other would give the DRDY error every three seconds or so, reducing speeds to 2MB/s.
If the PATA system disk is dying, that's fair enough, I'll have to replace that, too, but at least that can be something slow and it's not a problem.
