Humax HDR-Fox T2 Disk Error - Help please..

[Mudplugger]

Can anyone help?

My HDR-Fox T2 started having the odd minor freezing moment and slight 'blocky' areas of screen during playback of recorded content.

It is using custom firmware 1.02.32/2.18.

On the Web-If interface I got a red warning of a disk error, but I cant remember exactly what it said.
Using Telnet I then put the box into Maintenance mode and ran the fix-disk utility.

Each time it seemed to complete the short test OK but then exited the long test early...

This is what is being reported now on Web-If diagnostics:

Any ideas on what might be happening and what I should do to fix it?
Am concerned we might lose some of the content - so may consider a file transfer later today.
What's the fastest method to back up to a NAS?
Use Filezilla or similar and just copy across over the network?

All help, instructions or comments to resolve this would be gratefully received...

You could try this from a Telnet prompt:

humax# hdparm --read-sector 248537732 /dev/sda

If it gives you an I/O error, then do this:

humax# hdparm --write-sector 248537732 --yes-i-know-what-i-am-doing /dev/sda

prpr - thanks very much for the reply...

I set the thing going on a long disk self-test with options -x and -c and it's counted down so far from the 13000's to the 10900's.
Should I interrupt this - or leave it going?

 

[Mudplugger]

At this rate it won't finish until 5:05pm - unless it exits again....

 

[prpr]

Personally, I'd interrupt it as you already know the location of the bad sector from what you did previously.
Or I guess you could also leave the test running, but open another Telnet window and fix the bad sector from there.

 

[Mudplugger]

Thanks for your help prpr - very much appreciated.
I didn't know you could open more than one telnet window at a time (doh).
I'll try your second suggestion and use the commands you suggest...
As a matter of interest - what do those commands actually do?

 

[Mudplugger]

OK, on the first command, I did get:
FAILED: Input/output error

On the second command it responded:
re-writing sector 248537732: succeeded

What should I do now?

 

[Mudplugger]

Ongoing long test is still going, and faster than I thought.
It's already down to 5000.
At the rate of progress now, I calculate it to be about another 90 minutes remaining.

 

[prpr]

As a matter of interest - what do those commands actually do?

The first tries reading that numbered sector from the disk.
The second writes zeroes to it (the data is already gone so you aren't losing anything you haven't already) and hopefully forces the disk's firmware to remap it to a spare sector that works.

OK, on the first command, I did get:
FAILED: Input/output error

On the second command it responded:
re-writing sector 248537732: succeeded

What should I do now?

That's good. Wait until the test completes, then try the first command again and make sure it can read it without error. If so, then just give it another fix-disk run.

Can anyone help?

My HDR-Fox T2 started having the odd minor freezing moment and slight 'blocky' areas of screen during playback of recorded content.

It is using custom firmware 1.02.32/2.18.

Looks like prpr has helped you along but with any disk problem the first thing you should do is install the latest custom firmware. Fix disk has undergone several improvements since 2.18.

 

[Mudplugger]

Thanks prpr... It's just on the last 300 now, so will try the first command again as suggested...
I'm really very grateful for all your help, and the time take to explain.

af123 - am honoured to have your input too... Will update firmware if it all goes OK.

Have to say as a regular forum reader (but not a contributor - since I'm just a user that's a little bit more technical than the average punter) what you guys have done with the Custom Firmware/Web If etc is exceptional.
As today shows, your support for us less technically inclined is superb. Thank you.

Final update - all sorted.
Fix-disk completed fine 2nd time around.
Firmware updated to 1.03.12/2.22 - no problems.

Am a very happy bunny. Thanks.
