Error mount disk

I have 5 disks: 2SSD and 3HDD all formatted in BTRFS. With disk-utility it mounts them all at startup except an HDD! How can I solve it? Thank you!

What application is that? gnome-disks ?

Your /etc/fstab maybe provide some information.

Post the output cat /etc/fstab

❯ cat /etc/fstab

/etc/fstab: static file system information.

Use ‘blkid’ to print the universally unique identifier for a device; this may

be used with UUID= as a more robust way to name devices that works even if

disks are added and removed. See fstab(5).

The disc that does not auto play and DATI 1 GIOCHI ! All discs are perfect and have no errors!

Try mounting that disk manually and see if you get some error messages in the terminal.

Manually mounted from Dolhpin it gives me this error:

Si è verificato un errore durante l’accesso a «DATI 1 GIOCHI», il sistema ha riferito: Si è verificato un errore non specificato: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken

An error occurred while accessing «DATI 1 GIOCHI», the system reported: An unspecified error occurred: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken

Mount the disk/partition manually from a terminal with the mount command. Post the error message.

~ 26s
❯ sudo mount /dev/sdb1

~ 23s

No error!

It looks like a Dolphin problem!

You have to specify a mount point to mount /dev/sdb1 to.

For example at /mnt/tmp.

sudo mkdir /mnt/tmp

sudo mount -t btrfs -o defaults /dev/sdb1 /mnt/tmp

On the system the disk mounts but on Dolphin it doesn’t. It should be a Dolphin problem, in fact it doesn’t let me delete the files with “cestina” and with “eliimina”.

It doesn’t even come from system startup!

I have another identical disc and it mounts perfectly!
