For the last few weeks I've had the occasional warning from my DIY Windows Home Server that one of the drive wasn't 100% stable. It would work fine then... just stop. SMART said it was fine when I'd restart but...

Then on Sunday it died and wouldn't restart, so a quick trip to Frys for a new drive, whip off the case, stick in the new drive (replacing the cables as well just to be sure).

Powered it all up. Let it balance storage and... good as new, no files lost (though it did have to delete some backups as there wasn't enough space on the single drive to store everything) but way better than a crash and burn.

Now I might get an extra PCI SATA card and add a couple more drives...
