This HDD's history
The hard drive is 1.5TB, 6 years old. IIRC it's 7200RPM with a ATA133 interface, using the motherboard's onboard controller. It gave perfect service in a big desktop PC, then 1 year ago I moved it to a mini-itx TVPC with a little Celeron G530 2.4ghz and basically nothing else, booting up daily for movies/browsing for 1 year without any issue, then suddenly one day it could not boot, giving disk IO errors.
The TVPC has continued daily service using a Linux live USB.
Now a month later, I scanned the hard drive using badblocks -svw /dev/sda
It completed
- 100% write pass
- 100% read pass
- 62% of writing some other patterm (..5C.. or something IIRC) the last time I checked while it was going perfectly.
All with a 0/0/0 error count.
The next time I checked, the first two error counts in badblocks were very high, (a few hundred k and a few 10k) but it was running in screen with a limited buffer so I couldn't scroll back far enough to see where the problem started.
I tried to check the drive's SMART stats with hdparm but saw that the drive had disappeared completely! fdisk -l did not show it anymore. Even after rebooting, the hard drive does not appear. I did this remotely so I can't power it down at the moment. But I suspect it will probably reappear after power cycling.
This is kernel.log when things suddenly went bad:

(this last error repeated infinitely)
The big question
Any ideas why it was perfectly functional at the start of the test (completing a full write cycle, then a full read cycle, then 62% of some other cycle) then some hours later disappeared? Seems like maybe the HDD and motherboard is okay, but power supply or something else could be faulty?
One theory I have is that the power supply's ripple (noise) becomes too high with high-current-draw (using hard drive) but seems to manage with just a USB flash drive :/
