This checks that backing_device is Some, but then below you use unwraps
on that Option.
Just do

    for item in store_list {
        let Some(backing_device) = item.backing_device.as_deref() else {
            continue;
        };

            device: format!("/dev/disk/by-uuid/{backing_device}"),

^ since we then already have it available

            removable: true,

^ since we only iterate over items with backing devices
