[SMART] Preventing usage of some bad sectors

TriMoon · 12 December 2020 11:38

Hi, i recently found out that my HD has some problematic sectors:

Is there a way to exclude usage of all the bad sectors on that hard disk by the drive itself?

Because i’m using the HD with full device LUKS2 encryption in this way:

HD
 + No partition table
  + LUKS2 encryption
   + LVM with VG's as a way of partitioning the space inside the LUKS2 container.
    + VG with Filesystem of choice like ext4 etc...

(The LVM could be replaced with a single BTRFS ofcourse)

FYI:

This is my current setup where i have my current Manjaro installed.
The ESP is located on a different HD, which i plan to move to an USB-Stick to keep it more secure and locked-down in the future
I’m planning on doing a complete fresh install with latest iso, so reformatting the drive is not something i worry about, but i plan to use the same layout as mentioned above.
The bootloader to be used in the fresh install will be sd-boot again, so i probably will be using the Architect installer again.

Some interesting points in this thread.

One of the takeaways is that it is going to take a LOOOOOOOOOOOOOONG time.

TriMoon · 12 December 2020 14:57

Yea i already knew it would occupy my system for several hours
The HD im talking about in OP is a 4TB also
I already planned on doing something similar over night, but wanted to know if there is a way to get a list of all those bad sectors and just provide the drive with the info to make it all faster.
But i guess i need to try it that way?

merlock · 12 December 2020 15:07

From what I gathered from that thread, doing the complete drive and letting the drive itself map the bad sectors would be the only way to be sure.

TriMoon · 12 December 2020 15:13

Yea i was afraid of that, i’m now doing the dd way on a 2TB external HD who has same issues.
Thanks

you could also try to fix it with diskscan which is available in AUR

Also if not done already make sure you have a backup of your valuable data. Since this could indicate a dying disk.

TriMoon · 12 December 2020 15:37

My valuable data is either in the cloud or another HD

Thanks for the interesting link, i’ll be sure to try it via AUR
I see two versions with a git-version that is lower, which one you prefer?

SLaItEr · 12 December 2020 16:58

Neither, since I prefer not to have any bad sectors on the disk.

I would try the last version to be honest

TriMoon · 12 December 2020 17:23

Ok i build the latest version, seems it was also updated last as date.
Running it now on the external 2TB disk: ETA:20h48m45s

Update:

I did that as a test to see how it works on a external HD that i don’t use anylonger…
That last command seems to have finished prematurely:

Conclusion: failed due to IO errors
I: Scan ended at: Sun Dec 13 09:34:39 2020

I: Scan took 47395 second
I: Closed disk /dev/sde

How to interpret that?
Can that disk now be used without fear of bad sectors?

merlock · 13 December 2020 15:40

I would be wary about that I/O error. The drive’s controller could be flaking out as well. Check outputs of:

smartctl -A /dev/sde

Search your journal and dmesg for any entries around that time WRT diskscan and/or I/O errors.

It seems that you have some bad sectors marked out, but unless you can get to the cause of that I/O error, bad sectors could be the least of your worries; especially if you are going to put your critical data on it.

TriMoon · 13 December 2020 17:50

IIRC those were related to the USB port being reset due to inability to communicate with the external HD connected via USB.
Looked to me like the drive was unresponsive while doing it’s own relocation of the bad sectors.

Looking at this thread on Ars, the Reallocated_Sector_Ct is the number of sectors that have been marked, and are not visible to the OS.

However, the Current_Pending_Sector is the number of bad sectors that could be written to.

Me, I would try to see if I could hook that drive up to a SATA port on my mobo, and attempt the diskscan program again, before I would consider using it.

TriMoon · 14 December 2020 06:07

Very interesting thread indeed, thanks !

I can’t hook the drive to a SATA port because it is one of those things that are enclosed in a plastic frame and i would need to break it open…
But i will start the diskscan app again on it right after this reply, hope it fixes itself so i can use it again
This all is a learning curve for me, and i will need to do it with my HD of the current system also, which has way less as this one i hope…

SLaItEr · 14 December 2020 06:27

sorry for the late reply,

@merlock explained it perfectly

When you run it again I would (in this case) advice to add -r <file> to get an full log. Mind the file can get rather large, but it will show more details of all that is done.

TriMoon · 14 December 2020 07:16

I just started it with the -o flag, because the -r flag created a few MB in a fraction of a second already so i aborted
I will edit this post with the output if it isn’t too big

SMART remaps the sectors automatically. If it failed to do so it means the disk is days away from dying.

Yea seems this external HD has had it’s time ohh well, i’ll run a last long offline test.

The way SMART work is that modern disks have spare sector pool where a bunch of ‘good’ sectors are kept. With SMART when it finds a (logical) bad sector it will replace it with a good sector from this pool. When all 'good’sectors are used from out of this pool it will stop this progress on any logical sector even if there is stil room in the G-list. In this case you could try other ways to repair those Logical bad sectors.

When this happens you can try to use another solution like diskscan, zero-filling the drive on the unmounted drive (with sudo dd if=/dev/zero of=/dev/<harddrive> bs=<blocksize> ) or even try a low level format as last resolve (not recommended) .

Bad sectors can indicate a dying disk, but there are 2 kinds of bad sectors. Logical and physical… The first can be repaired (most of the time) and the later will be remapped. Even when there are multiple physical bad-sectors a drive can run for months, years even as long there is a way to remap them. Just keep an eye on the disk and if physical bad-sectors keep popping up replace it asap.

Well because this external disk seems to have died anyhow, how does one do the low-level format with these new drive types?
I remember way back in time we had ways to do so with the ancient IDE HD’s but i forgot how plus these drives are not IDE…
Could be interesting to try
