Secondery hard drive doesnt show up on file manager

Recently, I installed Fedora Linux f42 (KDE Plasma 6).
worked fine, so I started transferring my backed-up files from my USB drive back to the formatted machine. Now I have lost access to my second hard drive through the Dolphin file manager, but the HDD is still available through GParted. I can make a new partition, and they show up in Dolphin, but the one with my files doesn’t.

The second partition shows up on Dolphin (W2), but the first doesn’t (w)

What do you see in KDE Partition Manager? Is the “missing” partition visible there, and is the “Edit Mount Point” option in the Partition menu available for it?

3

KDE Partition Manager crashes every time I open it. That’s why I am using GParted.
can’t press mount in GParted.

The crash is being worked on I understand.

Is this a Windows disk that you are trying to mount?

What is the output of lsblk -f?

5

Also a dead end on the crash, not a Windows disk. I used it in Linux before it had some games and a lot of backed-up photos.

lsblk -f output - it shows up with no details (sdb1)

It’s worth noticing that the partition size is >2TB.

What is the output of sudo blkid /dev/sdb, sudo blkid /dev/sdb1 and sudo btrfs filesystem show /dev/sdb1?

When posting the outputs, instead of screenshots please post as preformatted text, using the </> button.

I managed to mount it using mount /dev/sdb1 /mnt, but every time I reset the PC, I need to do it again. the other drives just show up on dolphin

8 
/dev/sdb: PTUUID="3669afb0-d480-4269-b3d0-deb406da5a71" PTTYPE="gpt"

the second one had no output

Label: 'W'  uuid: 2364333d-b35b-4b3c-bd64-97c2621ec1dc
	Total devices 1 FS bytes used 323.17GiB
	devid    1 size 3.64TiB used 328.02GiB path /dev/sdb1

That’s suspicious.

What message do you get when mounting /dev/sdb1 from the command line (with sudo mount /dev/sdb1 /your/mount/point)?

10

Also nothing it just mounts

11

OK, so by mounting the partition from the CLI you can access the contents just fine, meaning it’s just a Dolphin issue.

If so, there’s also an option to hide specific devices in Dolphin, maybe you’ve used that option by mistake? Does the partition appear again if you access the Show all Entries option?

12

What does findmnt report for the device after you mount it in thr terminal?

14

/dev/sdb1 is btrfs clearly.

I’m not sure why it does not show up in the lsblk output.
Maybe an issue with the partition table?

15

Should I just move the files to another drive and format it?
I managed to fix the KDE partition manager and the drive shows up there

16

You may be able to fix the partition type and fix this.

What does this report:

sudo parted /dev/sdb print
17 
Model: ATA TOSHIBA HDWE140 (scsi)
Disk /dev/sdb: 4001GB
Sector size (logical/physical): 512B/4096B
Partition Table: gpt
Disk Flags:

Number  Start   End     Size    File system  Name  Flags
 1      1049kB  4001GB  4001GB               W
18

I think this will fix it.

sudo parted /dev/sdb
type 1 0fc63daf-8483-4772-8e79-3d69d8477de4
quit

I think the quit may ask you to confirm saving the change.

Now lsblk -f should report that the /dev/sdb1 is btrfs.

it not showing btrfs

I’m out of ideas. I guess you can do what you suggested and backup then reformat the partition.
