July 23, 2025Jul 23 Hello everyone, You're my last hope. I'm new to Unraid and hope you can help me. I can't mount an external USB SSD? Do you have any idea how I can get the SSD to work with Unraid? That would be great. Here's some information about my system. Thanks in advance for your help, and excuse my poor English. I can't mount the sdc/sdc1 Plugin ""unassign divices plus"" dont work. ""Clear disk"" dont work. Is it possible mouvt the ssd ""sdc"" per termnal?
