Help needed on wiping my HDR-FOX T2 with disk errors

Hi all,

I have an HDR-FOX T2 exhibiting the error where it constantly shows "*deleting..." and greys out a lot of the menus as a result. For clarity - I dont need to or wish to save any of the recordings on the device, I just need to get it up and running properly again. I've installed CFW 1.03.12_mod_3.13 and attempted the fixdisk utility which has been running continuously for last 3 days. Initially I was getting lots of "Error at LBA ...." messages, and now I'm getting ones like this:

Code:

Given that I dont need to save my recordings, is it likely to be quicker to just reformat the disk and then let the disk check run on an empty file system? I can't format the drive or do a factory reset from the Humax itself as the installation menu is inaccessible because of the deleting error. I see there is a reformat option in maintenance mode but wasn't sure whether that is what I need to use or not. If the answer is "just let the fixdisk finish" then I'm OK with that, but didnt want to waste time having it try and recover files that I dont need saved. The box came from my in-laws rental cottage and has over 800 recordings on it, so that's probably going to take some time to process, especially if a lot of them are corrupt.

Any advice gratefully received.

At prpr's suggestion I on an extremely long running fix-disk I found it much easier to just blank the disk using dd, (and then followed up with a normal Humax reformat).

I knew nothing about dd but after reading a few results of an internet search came up with:
dd if=/dev/zero of=/dev/sda bs=1M

So do I just launch the CLI in maintenance mode, run the command exactly as you have typed it above, allow that to complete, exit maintenance mode and then from the Humax box itself perform a format from the installation menu?

Yes. But it would be useful to know the state of the disk both before and after the dd command. Run this either side and report back:
Code:
humax# smartctl -a /dev/sda
Make sure you don't have any other USB disks plugged in.

I knew nothing about dd but after reading a few results of an internet search came up with:
dd if=/dev/zero of=/dev/sda bs=1M
...
Adding the option oflags=direct to the dd command may be useful, as I found that it seemed to bypass some sort of error-checking that would prevent a pending disk sector from being written. I acknowledge that this suggestion is verging on cargo cult programming.

I believe you have to be about 110 with a long white beard to know much about dd.

Ran the dd command as advised, all went through OK and cleared the error on the Humax which booted up and prompted for a format which I did without issue. Just done the fixdisk and that also completed without forcing me to do the long test this time, so fingers crossed it looks OK. Here's the subsequent output from the command @prpr suggested:

Code:
humax# smartctl -a /dev/sda

Apparently your disk is fine and it was just the Humax s/w that got confused.

In case any future readers come here with a similar problem (the "Deleting" loop), the simple solution with CF is this command rm /mnt/hd1/filebglastop.dat at the Maintenance Mode telnet command-line. It's run automatically at the end of the Maintenance Mode fix-disk (NB Wiki item needs updating for the current CF, which doesn't bother to ask, unlike v2.12), but that's quite a long-winded way to do it.

This problem can also occur on HDs, where fix-disk isn't available. The location of the file filebglastop.dat would be different, presumably /media/sdx1/filebglastop.dat.

Here's the subsequent output from the command @prpr suggested
I don't particularly like the output of 187, 188 and 189, nor those "UNC at LBA ..." errors, but would continue to use it if it were mine. Worth keeping an eye on if you have any more trouble though.

I believe you have to be about 110 with a long white beard to know much about dd.
That would be Trev, then.

Is that a useful thing to add to my disk recovery article as a first step rather than universally reaching for fixdisk?

I think the reason for using fixdisk is that the deleting problem is often accompanied by some file system corruption and it is a better long term solution to fix both at the same time.

The LBA values (0x0fffffff) look a bit dodgy, even if it is a valid 512-byte sector address for a 1TB disk.

According to the self-test log the disk once felt poorly but according to the current stats it got better (no reallocations, no pending sectors) by itself, when dd zeroed itfix-disk tested it with hdparm --read-sector. This also seems dubious and leads to the question of what this disk firmware is actually up to. Open source disk firmware -- now that would be a thing!

It didn't get better by itself. Writing all those 00's with dd has caused the disk firmware to declare what was probably a previous weak write (or similar) on that dodgy sector to be good now.

I intended "by itself" as a non-technical version of "without remapping any sectors". On reflection the dd operation is doubtless responsible as you say, and maybe the firmware isn't so suspicious after all.
