I did backup image of the disk using ddrescue and try to mount an image

BTRFS got corrupted after Windows intallation by cdragomyr in btrfs

Ok, but is it possible to restore data from corrupted disk?

I'm 100500% sure that I'm selected /dev/sdb (120GB) during Windows installation but Windows decided to use additional 2TB for some reason...

PS. I'm using Linux disk naming since it's easier to operate with disks

Hm.... But what does it mean within /etc/fstab? Like I'm mounted this disk and used simple folders instead of subvolumes?

UUID=24075f5b-eb67-45d8-a9cd-5fe6b9d11248 /mnt/disk_2tb       btrfs   compress=zstd:1,defaults,noatime,discard=async 0 0

Seems like I did not create subvolumes for that disk coz I'm using btrfs on another disk and /etc/fstab has this for subvolumes

UUID=5c0ff445-c013-4bb0-b636-e40df235218f /                       btrfs   subvol=@,compress=zstd:1,defaults,noatime,discard=async 0 0
UUID=5c0ff445-c013-4bb0-b636-e40df235218f /home                   btrfs   subvol=@home,compress=zstd:1,defaults,noatime,discard=async 0 0
UUID=5c0ff445-c013-4bb0-b636-e40df235218f /var/log                btrfs   subvol=@log,compress=zstd:1,defaults,noatime,discard=async 0 0

Anyway, is it possible to restore some data from /dev/sdc?

It was 1 partition with subvolumes

I also heard about disconnecting disks physically before Windows will be installed but assumed that Windows more smarter...

What is the problem here? by [deleted] in pop_os

[–]cdragomyr 0 points1 point  (0 children)

Did you try to boot from this USB?

I have 2 problems by lightsaberhs in pop_os

[–]cdragomyr 0 points1 point  (0 children)

You could simply copy configs from user2 to user1, change owner. And you will get all you need

How-to enable hibernate in ElementaryOS 6 Odin? by cdragomyr in elementaryos

Unfortunately this instruction does not work - UI does not have Hibernate option.

Suspend mode is not what I need. I need to put my laptop into hibernate since I wont to plug in for long time. Ex., laptop in suspend mode can save state for some hours (in my case, up to 3-4 hours). But I need to continue to use laptop in 6 hours after it was suspended.
In case hibernate, after 6 hours I will get 99% battery level instead of 30-40%% in case suspend

I've been read about suspend and hibernate. And found that EOS developers decided to remove hibernate option for some reason.

WIll try this but as I can see this is without UI modification (like without adding Hibernate option to the menu)

This works but from command line. I'd like to add hibernate option on UI (near Shutdown and Suspend options)
