Hello! As the title states, I’m having trouble mounting my externals on my OLED Steam Deck. I swapped the SSD from my LCD as soon as I confirmed the device powers on and I have updated to the latest stable version. Everywhere I read seems to imply that I must’ve not removed the drive from Windows properly or have fast boot enabled. I have confirmed that these are not relevant to my problem. I have tried ejecting the disks and shutting the Windows system down before removing them.

If I cannot find a solution I will spend a day reformatting to EXT4 and transferring about 10TB on two drives, but I’d like to avoid that if I can. I’d rather do that than restore the Steam Deck to factory.

My best guess is that some setting got flipped somewhere, but I’m not very familiar with Linux.
