I think my disc is failing

[prpr]

I was quite impressed by this - it did what I wanted to do on my PC anyway (although not Humax related).

Probably my final update on this thread, as my new 1Tb drive is now fitted.
Here's what I did.

1) Made sure I have the latest copy of the schedule BUT, this turns out (as posted elsewhere) not to have been necessary.It was restored automatically.
2) Remove the drive. It's a very easy dismantle and removal. One cross-head screwdriver is all that was required. The Disk is fitted into a single unit that also contains a fan, so take care to remove the fan connector from the main board before pulling the drive unit out.
3) Next is where I had the only problem. I put both old and new drives into a dual external USB caddy, but my laptop did not recognize the drives. I hoped to at least see drive letters but nope - nothing.
4) I installed the Seagate DiscWizard software, as it can easily clone a drive, but this software will not run unless it can identify a seagate or Maxtor drive in the system, and it would NOT detect my seagate drives via USB. So, unless I fitted them internally to a desktop machine I was unable to do any cloning. (I thought I had Acronis True Image here but I didn't!)
5) So, next I installed the new drive, untouched, into the Humax, and from here things got very good! Good old hummy identified the drive, told me I needed to format it and after a couple of button clicks off it went. For a 1Tb drive it competed in a couple of minutes, which surprised me.
6) After formatting, used the 'Back' button to return to the main media menu, checked the schedule and everything was there. No need to restore from my backup.
7) Plugged the old drive into a USB caddy and it was recognized, so I just set the media to USB, located the video files, and selected the top menu for copy, used opt+ and set it to copy back to the new drive. It's running now and will probably keep going for a couple of days, though I'm not really sure of this.
8) Connected via WebIf page and I was given the option to download all the WebIf software again. After letting it finish the download and resetting on the Humax, averything was again as before.

End result looking good. I hoped to do a fast disk clone, but this is working fine, provided we don't have any power failures while it runs!

I hope this helps people thinking about replacing their hard drive. I'm pretty sure that this method would also work for updating the drive from 500Gb to 1Tb.

All the best to those who provided valuable information and gave me the confidence to do this. I can now reformat the old drive and see if I can fix any remaining sector errors and keep it as a spare.
Alan.

The schedule isn't stored on the drive, only the custom firmware schedule backups.

You probably want to edit your post: for "cross-thread" try "cross-head", and for "filled" try "fitted" (I know I know, predictive spell check!). I will delete this paragraph later.

I just got the message below, and I am running full disk check (option 3) from the maintenance menu as suggested

!! WARNING !!

There appear to be some hardware problems with the internal hard disk on this device.

Disk pending sector count is: 1
Disk offline sector count is: 1

Go to disk diagnostics


Having a quick check on the progress ( option 4) I get this message.



Does the "completed real failure" part mean it is done? It has only been running 20 minutes and I can only hear fan noise.

 

[af123]

Yes, it's done and has found the bad block. If you run the fix-disk process (option 1) then it should repair it for you.

 

[4ndy]

Cheers af. When I tried running option 3 again it said it was running and would finish at19:50.

I will run option 1

 

[4ndy]

Check disk now completed.

I got the previous warning message again whe I connected via webif and clicked on the acknowledge current disk faults button. I now get a message I can't clear. Any advice please?


!! WARNING !!

There appear to be some hardware problems with the internal hard disk on this device.

Disk pending sector count is: 0 (was 1)

Don't panic; for help, visit wiki.hummy.tv

 

[AlWilson]

I had the same myself after acknowledging the new count, but when I closed WebIf and logged in again it was gone. For me it only remained gone a short time, which is why I replaced the disk, but for you it might be different. It depends on whether the bad sector count rises again.

 

[af123]

Could be a bug in setting the count back to zero from one. I'll look.

 

[af123]

Looks like it was - try webif 1.0.7-1

I have just got this message again, this time with a count of 3,which seems a little strange as I
have not had a count of 2. Besides, the counter was reset to zero after the last occurence.

The hard disk data is below. If I understand the second block of data correctly, it is consistantly failing at the same place (and this is the same place as last time). Does this mean I should not worry and just let the disk error correction deal with the error?

Should I be transferring off all my files and hunting down the reciept, which I believe has six months left?

It is not showing any pending sector errors at the moment but it is not clear if the problem at LBA 219658 was fixed. The results in the second block are from the last time that fix-disk or smartctl was run. You could try running fix-disk from CF 2.19 to see if it fixes the problem.

A reallocated sector count of single figures is not really a problem unless it keeps rising. I find that it tends to have a few bad days where it will increase, then it will be stable for quite a long time. Mine was stable at zero for a long time, then increased to about 95 over a few days and was stable for a few months. It then had another burst to its current reading of 148, where it also has been stable for a few months. When this figure gets to over 1000 it is probably time to think about replacing the disk.

 

[4ndy]

Thanks xyz123, for the comprehensive reply.

I did run the fix-disk again but it found no issue. I would obviously wish to get the disk replaced under warranty, I.e. Before next May. Apart from being a little noisy it seems to work okay. Difficult to return the HDR on the basis of CF diagnostics.

I have started to copy everything off to an external drive in case it needed to go back. I planned to reformat the HDD and copy it all back. Do you think it will help (particularly with the disk noise) or am I wasting my time? It is a very slow process.

 

[MartinLiddle]

Do you think it will help (particularly with the disk noise) or am I wasting my time?

I fear that you are wasting your time.

 

[xyz321]

I did run the fix-disk again but it found no issue.

Does it still show a read error for test '# 1' at LBA 219658?

 

[4ndy]

I don't think so. I don't know how to convert the 'when' into a date. But I think the top two lines are yesterday's test in maintenance mode.

I have noticed that the error rate values in ID 1&3 are climbing quite quickly.

The 'when' values in the self test logs are taken from its count of power on hours. Attribute 9 gives the current power on hours so this would suggest that the test was performed 8087 - 8065 = 22 hours ago. This assumes that it has not been turned off during that time.
