Cannot mount my second ssd

[p1xlize]

Hi, i wanted to split my ssd in kde partition and after i split my ssd, got an error. I cannot mount my drive.

An error occurred while accessing ‘420.8 GiB Internal Drive (sda1)’, the system responded: The requested operation has failed: Error mounting system-managed device /dev/sda1: wrong fs type, bad option, bad superblock on /dev/sda1, missing codepage or helper program, or other error.

When i do lsblk the drive is present but i cannot mount it.

this is the output. I cannot even format this disk. I’d like to fix it without losing my files.

try with testdisk.

this is the output. It’s like this disk doesn’t exist

What shows?
ls /dev/sd*

[p1xlize]

/dev/sda  /dev/sda1

idk i cannot mount, but my pc sees it.

You only can mount a partition when there is a filesystem on it. The devices will show even without filesystem on it.
