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 :/

All we know right now is that there is a hardware problem. It could be caused by the CPU (possibly because of overheat), the on-board ATA controller, the data cable, the power supply or the hard drive itself.

Since the simplest to check is the CPU's temperature, that's where I'd start. Although this type of error being caused by CPU overheat is less common today, I've seen it numerous times on older machines.

If the CPU temperature is OK, you should probably try a different data cable or install the hard drive in another computer to see if it works properly.

Finally, if the issue is still not clarified, you may have to try a separate ATA controller or power supply to finalize the diagnostic.
