Unable to (re)mount BTRFS Partition | Arch Linux Community | Page 1

So basically my Drive has been randomly locked up itself like 3 Days (Happened while working on a Coding Project even tho i stil had 12GB left of Disk Space but whatever stuff like this happens)
so i just poweroff the Machine and unplug the Disk and hook up externally and boot up my PC again and to my Suprise it was shown in the list of Drives in Thunar so i click on it and get greeted with a "Superblock" Error so first thing i do is check if i can like mount it to a folder atleast specifically /mnt/tmp which then greets me with this

sudo mount /dev/sdd1 /mnt/tmp
mount: /mnt/tmp: can't read superblock on /dev/sdd1.
       dmesg(1) may have more information after failed mount system call.

afterwards i try seeing if btrfs check can give me any results and well it does give me a few errors but not any that seemingly stick out to me

https://privatebin.net/?74c17101374834b2#ErNyUtq3J6Fu1FifPdUHCUfjbUNFpGz58RWTnjM2CNUU

same with the btrfs rescue command which just tells me all my superblocks are fine and that there is no need to recover

https://privatebin.net/?af930d7d3b28fc27#FSqudMjbTAyhbCgnr3zYZKLRPsKtW9koUgaJRLpSSNh5

which afterwards still trying to mount it with the above same terminal output and now i will get annoyed obviously so i see if my dmesg has something and welp im gonna be honest i have no idea what any of this means X_X

https://privatebin.net/?8e03872f91533dea#CSKuSuvZfNcXizsLKuQiEEyUXyP2kgvWUwCFu4yVUq79

and since i obviously also have no idea how to fix it decided to ask yall :P
now i do wanna say that i am too poor to afford hard drive so my last backup was like from 5 Years Ago which sucks but yea in the worst case ill may just get this atleast X_X
i am just honestly super confused as to how and what exactly is going on and if its even worth fixing it like i do not have the money to go to a rescue data recovery service because it costs like 800€ usually overhere :((((((

How does the disk result in a smart test

grim shard How does the disk result in a smart test

ooo i uh forgot to do this uh wait let me fast send you it because thats something i forgot X_X

grim shardBOT Apr 27, 2025, 3:38 AM

#

I probably don't know how to fix but running a recent smart test would be helpful for the other people who'll look into it

#

here is my smartctl output

#

i did not knew uh how to do it really so i just used the entire disk instead of just sdd1 like usual

grim shardBOT Apr 27, 2025, 3:54 AM

#

Ya use the entire disk

#

Your disk fails

#

im sorry

#

Your disk is dying

final tulip Apr 27, 2025, 3:55 AM

#

so no way for me to save it? :(((((

grim shardBOT Apr 27, 2025, 3:56 AM

#

you need to recover everything as soon as possible

final tulip Apr 27, 2025, 3:56 AM

#

oof fuck X_X
uh well ill see if a repair shop has open at Monday X_X

dreamy basin Apr 27, 2025, 3:57 AM

#

before opening: "can't be that bad surely"
after opening: "oh damn it is that bad"

final tulip Apr 27, 2025, 3:57 AM

#

hey i did not knew :((((

#

its been acting weird since 4 days X_X

#

if i knew before i wouldnt have even used it X_X

#

but i thought i could fix it sadly myself :(((((

#

rip me rescue costs 1500€ X_X

#

i dont have that much money :((((((

grim shardBOT Apr 27, 2025, 3:59 AM

#

can you see the partition

final tulip Apr 27, 2025, 3:59 AM

#

uh what?

#

like in Thunar or gparted? >.>

#

well sure i can

grim shardBOT Apr 27, 2025, 3:59 AM

#

is a partition like sdd1 present and recognised by the kernel

final tulip Apr 27, 2025, 4:00 AM

#

well uh yea? >.>

#

thats the entire reason why im mounting sdd1

grim shardBOT Apr 27, 2025, 4:00 AM

#

i would advise to create an image of it

final tulip Apr 27, 2025, 4:00 AM

#

or like uh always trying to fix sdd1 specifically

final tulip Apr 27, 2025, 4:00 AM

#

grim shard i would advise to create an image of it

but isnt it a bit unsafe with dd?

grim shardBOT Apr 27, 2025, 4:00 AM

#

if you run the dd command correctly, it's safe

#

also uhh there are other programs that can image a disk

dreamy basin Apr 27, 2025, 4:01 AM

#

Can you mount the partition read only?

final tulip Apr 27, 2025, 4:02 AM

#

dreamy basin Can you mount the partition read only?

nope will still tell me about bad superblocks X_X

final tulip Apr 27, 2025, 4:02 AM

#

grim shard if you run the dd command correctly, it's safe

uh hm

final tulip Apr 27, 2025, 4:02 AM

#

grim shard also uhh there are other programs that can image a disk

well which ones by chance? O.o

grim shardBOT Apr 27, 2025, 4:02 AM

#

clonezilla

final tulip Apr 27, 2025, 4:02 AM

#

but i can honestly wait til monday

#

and like call them

#

and if its actually 1500€ i will just do it with clonezilla

grim shardBOT Apr 27, 2025, 4:03 AM

#

fair
good luck

final tulip Apr 27, 2025, 4:03 AM

#

thanks X_X

#

wow now i feel even more stupid :c

#

like i wish i wouldve just called sooner honestlx X_X

dreamy basin Apr 27, 2025, 4:03 AM

#

there's ddrescue and hddsuperclone too

final tulip Apr 27, 2025, 4:03 AM

#

then i atleast would not have to wait until monday -.-

data recovery is generally expensive but should probably be less than that

grim shardBOT Apr 27, 2025, 4:05 AM

#

you could try imaging the disk and see what you can do with it

final tulip Apr 27, 2025, 4:06 AM

#

dreamy basin data recovery is generally expensive but should probably be less than that

well they write if its a physical defect its like uh 500€ - 1500€

#

if its "just" the PCB its 350€ - 1250€ X_X

#

but i assume its more of a logical error? >.>

#

because those are like 150€ - 500€

#

and besides i also have a spare 2TB SSD he can like put it on as the dead SSD is also a 2TB :P

#

but ugh i really should invest in a External 4TB HDD someday -.-

dreamy basin Apr 27, 2025, 4:08 AM

#

I would investigate the options above first and see if you can save yourself the money tbh

final tulip Apr 27, 2025, 4:09 AM

#

well im scared of plugging it back in tbh :((((((((((

#

like what if the reconnection causes it to rot further :(((((((((

dreamy basin Apr 27, 2025, 4:22 AM

#

a logical issue doesn't turn into a PCB/physical issue (though PCB issues can cause logic errors, afaik)

point is, even if it were to get worse as a result (and it probably won't), it wouldn't be a big deal and make things entirely unrecoverable.

Data recovery professionals have the tools and knowledge to go to some crazy lengths in order to pull data

final tulip Apr 27, 2025, 4:22 AM

#

woa :000000

dreamy basin Apr 27, 2025, 4:23 AM

#

I would try using ddrescue first because it's built for these kinds of situations (old as it is), the other one I suggested was more HDD specific ><

final tulip Apr 27, 2025, 4:23 AM

#

hm ill try ddrescue then? :0

#

is there uh a specific set of commands itd have to use? >.>

dreamy basin Apr 27, 2025, 4:24 AM

I found this guide after a quick Google and it seems fairly good:

Guide to Using DDRescue to Recover Data - Technibble

I've decided to document some real-world examples of DDRescue from in the shop. I plan on doing this in 3 parts to cover the most common scenarios.

#

but yeah this is going to be a CLI job

final tulip Apr 27, 2025, 4:27 AM

#

welp time to wait 16 Hours for the image to be created X_X

#

afterall putting 2TB SSD into a Disk Image is uh interesting

final tulip Apr 27, 2025, 9:31 PM

#

Update: so after getting through 99.61% (yes im not kidding) i actually ran out of space :(

#

deicded to stiill wanna mount it and welp was greeted with this

$ sudo mount 2TBSSD.img /mnt/tmp
[sudo] password for retro-hax:
mount: /mnt/tmp: wrong fs type, bad option, bad superblock on /dev/loop0, missing codepage or helper program, or other error.
       dmesg(1) may have more information after failed mount system call.
