fix-disk: sda1 - Unrecognised partition type

Erp_Is_Not_Spam said:
Fantastic! Things are looking pretty good then, it seems! Oh this makes me really happy. :)

I think I'm going to FTP off some choice recordings this afternoon, just for peace of mind's sake.

Thanks again for the help, everyone!

Just to remind you.
If you use FTP then the files will remain encrypted. This is fine if you only ever intend to put them back on the same Humax box to play in the future.

If you intend to play them elsewhere you should either:
- use the webif decrypt function first
Or
- copy them to USB drive (for HiDef you will need to flag them as decrypt first).

Hi,

It's the OP here, from nearly 10 weeks ago. Sadly the inevitable seems to have just happened, as my Humax hard-drive has just started exhibiting serious problems again - in fact pretty much any function that needs to access the hard-drive seems to lock-up the device, whilst making worrying hard-drive clicking noises.

Thankfully since my last troubles I've managed to ftp off almost all of my most important recordings, so if it is time to go for a brand new hard-drive then it'd be of no great loss.

However, I thought I'd give Maintenance mode a quick try again, just in case the problem was fixable...

So I rebooted into Maintenance mode, chose the fix-disk option, and after a short wait I got the following result:

Please select option: 1

Any help would be much appreciated, but I'll totally understand if there's none forthcoming - I've already had far more than my fair share here, after all!

Many thanks,

Try CF version 2.20.

Hi xyz! Thanks for the suggestion!

I've now installed CF 2.20 and am currently trying a fix-disk again. So far it's got further than last time, so the new CF has definitely helped.

It looks like it succeeded in "re-writing a sector" after it attempted to repair a bad-block.

It then went on to start a short self test, at which point it reported "Pending sector error(s) found" and "LBA has not yet been found", and then it moved onto a long self test instead.

So I guess I'll report back here in about 3 hours time with how that goes... ;)
 
By the way, is there any way that I can re-start the long test so that it automatically answers "Yes" to any prompt to "Attempt repair of bad block?". That seems to be happening a lot... :eek:
 
Hi again,

More than 31 hours later, and the process is still going...

I'm long past the stage of repairing the bad blocks, and I'm now (apparently) searching for inodes and marking blocks as in use.

Here's the latest output from the session:

Is it usual for this part of the process to take so long, or is this a sign that the disk is essentially irreparably damaged?

(Basically, is it time I called this quits?)

(Basically, is it time I called this quits?)
Click to expand...
:eek: The process it is currently going through is supposed to show the names of any files which contain the bad blocks. It does take a long time but since you have quite a large number of bad blocks it will take a very long time.

I suggest you try to abort it with ctrl-C. When you get back to the prompt re-run fix-disk with the -B and -P options. These options will make it skip the initial tests and move to the file system checks.
 
I don't know whether it was because I closed my previous session beforehand, but when I started a new telnet session and tried the killall command you suggested, no such process was found. Even when I tried a ps command, no "fix-disk" process was listed.

Regardless, I've now kicked-off a fix-disk -B -P, and that's currently on its merry way...
 
Alright, so that fix-disk -B -P finished in fairly quick time, possibly "successfully" (?). I've attached the log to this message, although sadly Windows 8 Telnet doesn't seem to keep much history by default (I should clearly install Putty or something instead).

However, I've just exited Maintenance mode and rebooted the Humax, to see what its current status is. When I first went into the Media menu, it showed 100GB more than I expected in free space, and no recorded programs listed at all. Then when I rebooted for the second time, I could no longer even access the Media menu, and instead it showed a "The disk needs formatting to use recording features" message (or something to that effect)...

This sounds suspiciously like the error message I initially encountered when I wrote my first plea-for-help message here, but I'm not sure if the underlying cause is the same, so I don't know whether I should try out the exact same efforts to fix it (hdparm --repair-sector..., etc.)?

Any suggestions what to try next?

Is this still the original (factory fitted) disk? The figures look reasonably good apart from attributes 197 & 198 which suggest it is still having problems reading some sectors. However, the raw read error rate looks very low in comparison to other disks.
 
Here are some options (none of which are very satisfactory):
  • Run fix-disk again - it will take a long time since there are still 95 sectors to fix. Also there is no guarantee of success; or
  • Remove disk and connect to PC, then run Seatools to try to fix it; or
  • Try a security erase. This will wipe all the data but you have probably lost everything anyway; or
  • Fit a new disk - probably the safest option in the long term.
 
Interestingly, Line 194 suggests that the drive has never gone above 40 Deg. C which means the fan would have never turned on (unless forced on by the 'fan' utility), I wonder how it managed to keep so cool
 
Those SMART figures are all bizarre IMHO (0 seek error rate, 1 start/stop but 1772 power cycles, temperature, raw/recovered errors etc.).
