Hard Disk Failure

Hi - Yesterday, my hard disk failed 1 year and 6 days after purchase ! Just out of warranty so I checked the Maintenance Option on this great Forum site, and have been running Opt 1 Fix Disk for a couple of hours now. Not sure if I should be worried yet since it clearly says in your instructions that it might take several hours. It does seem to be looping however, struggling with Block Inode 0 as per the enclosed screen shot - been round this lot several times. Is that repetition normal or should it have moved on - ie the disk is knackered ! Or can I do anything else to try and recover it ? Many thanks

It goes on to say -
testb: Invalid block number 0
Block 0 is marked as in use

Searching for inode...
debugfs 1.42.10 (18-May-2014)
 
You don't know the disk is knackered. There might be absolutely nothing wrong with it and it's just the filesystem that's corrupt.
What do your SMART statistics show? Use "smartctl -a /dev/sda" at the maintenance menu's command line option.
If there's stuff on there you want to keep, then you should be thinking about getting it off there and on to another disk pending a re-format.
 
Even if your disk is fubar (which it probably isn't) I would check on the manufacturer's website as you may have a two year warranty. You have an advanced format disk and the current fix-disk program does not reallocate unreadable sectors effectively. As prpr suggested, take a look at your smart statistics and post them here (paste within code tags, or use code the option in the forum format menu).
 
Hi - the fix disk did not cure the problem so I did the smart thing you suggested - here's the result


-----------------------------------------------------------------------
Now starting a system command prompt. You can make this the default by
enabling 'Expert mode telnet server' on the web interface settings page.
-----------------------------------------------------------------------

Humax HDR-Fox T2 (humax) 1.03.12/3.00

To return to the menu, type: exit

humax# smartctl-a/dev/sda
/bin/sh: smartctl-a/dev/sda: not found
humax# smartctl-a/dev/sda
/bin/sh: smartctl-a/dev/sda: not found

Have I done something wrong or is it curtains for my disk ?

Cheers
 
Sorry - not too clear in this font - done it again and got this

Whilst the bad sector count is not too bad at this point, it has other errors that would be worrying me.
It might be fixable and carry on OK, but I'd be looking at getting a warranty replacement.
Have you checked on Seagate's web site?
I wouldn't assume it's only 1 year until you've checked here...
Actually, I just tried it (seeing as your model/serial number info. is in the above) and it says it's an OEM component, so you have to refer to whoever you bought it from.
 
If you want to try resurrecting it, you could start with this:
Code: 
humax# hdparm --repair-sector 2104512 --yes-i-know-what-i-am-doing /dev/sda
humax# hdparm --repair-sector 2104513 --yes-i-know-what-i-am-doing /dev/sda
humax# badblocks -sv /dev/sda2
You might need to repeat the sector repairs in sequence up to 2104519 before doing the "badblocks" command.
 
If the disk is in warranty you could get it replaced, but you should be able to get it up and running again. Take a look at this thread here. You have a sector/ sectors which needs/ need to be reallocated, but because you have an AF disk, 8 logical sectors (1 physical sector) have to be rewritten and fix-disk can't handle this yet. The sectors can be reallocated from the command line in telnet.
First you might have to install the hdparm package (I'm not sure if this is already installed by default):
Code: 
opkg install hdparm
The next steps are best done in maintenance mode. The first problem sector is at LBA 2104512. I would try reading this first:
Code: 
hdparm --read-sector 2104512 /dev/sda
I think that fix-disk will have corrected this one so the read command will return lots of zeros. If this is the case, read the next sector:
Code: 
hdparm --read-sector 2104513 /dev/sda
If this returns an error message you need to write to this sector to force reallocation:
Code: 
hdparm --write-sector 2104513 --yes-i-know-what-i-am-doing /dev/sda
Then read the next sector and write to it (as above) if it is unreadable. You will probably have to rewrite 7 sectors in total (assuming that fix-disk did the first one). When reading the sectors starts returning data rather than error messages you should stop rewriting them. I would then run fix-disk again and see if it goes to completion. If so, leave maintenance mode, check your smart statistics to see that the sectors have reallocated, and check that the unit is working properly again.
 
OK Thanks both - I've done the re-write on sectors 2104512 to 4519 as suggested and am now doing the check for bad blocks - it will take a while !
I'll post the results

If your hard disk is broken, how and where would it install to?
Obviously the tools for fixing the disk can't be on the disk itself. It's in the flash memory (/sbin/hdparm).

I don't understand your post. I thought that the hdparm package was installed in flash, I just was not sure that it was a preinstalled default package. There are a number of packages that are stored in flash which aren't installed by default when the custom firmware is loaded.
 
OK the bad blocks check is finished with zero bad blocks found, so I rebooted into normal mode and the Humax HDD Test passed OK but it's still showing zero gb as available used reserved and total, so is there anything else I can do in Maintenance or maybe tomorrow I'll try accessing the disk through File Manager in Windows to recover the files on it. Any advice greatly appreciated = Thanks

There is a version of hdparm built into the CF (the bit you install from USB). This is what runs in maintenance mode, for reasons explained previously. There is also an installable package, which resides in /mod/sbin/hdparm when installed. This is a 'useless' package as the file is already built in to the CF. I can only assume that at some point in history it wasn't built in to the CF and that this is the reason why it's still in the package repository.

Did you run fix-disk again? You've fixed the disk surface (for now), so now you need to fix the filesystem.
 
OK - I thought after my last reply that you'd probably say that, so I will run fix disk now - I'll let you know the result

That was quick - about 20 mins doing lots of Cleared and Fixed - rebooted into normal mode and it now sees the disk data - only it's reporting

885.8 gb Available
20.2 gb Used
114.0 gb Reserved
1000.0 gb Total size

So I checked the Browse Media List and the files all appear to be there -

reporting -82849247232 bytes (-9%) as Used
903.54 gb as Free (101%)
79.68 gb in Dustbin (8%)
on a Total Space of 906.06 gb

I am now copying the files off to a spare disk, and presumably will have to re-format or what ?

Cheers

By the way - for copying off onto an external hard disk, I use Cute FTP 8.3 - I've found it very efficient over the years !
 
What do you mean by "external hard disk"? I take that to imply a drive connected to the Humax by USB. I don't see how copying to that using FTP can be efficient at all, because unless you have somehow invoked FXP (file exchange protocol, which I am not sure the server is capable of), the data would need two passes on your network followed by one on USB.
 
Hi Black Hole - no, I mean a portable hard disk connected to my desktop computer USB port, which is running Cute FTP and copying direct from the Humax to the H/Disk over my ethernet network

They are some bizarre numbers, which probably indicate your filesystem is not totally happy.

I probably would. You'll have to reinstall the Webif and all your packages afterwards.
Need to keep an eye on those disk SMART statistics as well...
