Symptoms of a failing HDD?


I've been experiencing problems that appear to have come on rather suddenly.
(relating to the HDR-T2.. in case you think I'm going to get rather personal!)
Symptoms are:
  • Playback of recorded programmes: Humax crashes, reboots (says CRASHING on front display, or similar). This occurs at a random time after power on, but then seems to happen frequently after that. This has not happened the last couple of days, but has been replaced with:
  • Playback of recorded programmes: Audio and video freeze, requiring hardware power reset - wife said 8 times during Holby, but no specific time interval.
  • Live television hangs - picture freezes, but audio continues, requires hardware power reset.
  • Playback of mp4 video from external drive - this also froze once too, requires hardware power reset.

Obviously, the hardware reset is necessary as the box is unresponsive to the remote.

What I've tried:
  • Disconnected network, disabled sharing etc.
  • Upgraded the CFW to the latest supported version (i'm on 3.03).
  • Run the fix-disk from the telnet facility (or is it disk-fix?) - short test completed, no error.
  • Checked internet for similar symptoms.
The crash.log tells me nothing except a timestamp of when a crash occurred (doesn't seem to list all instances).
The Hard disk info says

(can't see a good way to format the above, sorry)

The old_age and pre-fail concern me a bit.. the box is 2.5years old with pretty much daily use.

I'm hoping someone can come along and be fairly certain of a HDD failure - replacing this would be preferable to buying a new box. Is this likely?
Or, is there anything else I can check? I'm reluctant to do a factory reset right away, though could be the next thing on my list when I have some more free time.

That disk doesn't look in bad shape. The 'pre-fail' and 'old_age' comments are just saying what those attributes would indicate if their threshold were exceeded, which it hasn't been.

If you have only run a short disk check, then you need to run the full fix-disk process. That's option 1 on the maintenance mode telnet menu.
See Black Hole's guide for more details:

I'd also follow Black Hole's standard guide to troubleshooting crashing faults:


Thanks guys, I'll do a full fix-disk overnight tonight, and report back. I have more confidence in the HDD, hopefully I don't end up with other failing hardware!
I was following BH's guide, I think I did most of it based on the the initial symptoms (Section 2).. which led me to the telnet diagnostics. Great to have such tools and guidance :)


I've done a fix-disk -x-c and a long self test. We'll see how it goes now.
Incidentally, after the fix-disk -x-c (friday night) the box seemed to operate well for over an hour on saturday. So fingers crossed :)
