You also shouldn't delete from the SD card using your laptop anyway. Always use the in-camera format. This was a bad workflow from the beginning, no idea why you would ever click "Delete after import" when importing directly off an SD card.

Also a good idea to copy to multiple locations when importing. When I do professional work and import into Lightroom from SD card I have it set to create two copies - import to my external SSD (the "working" copy) and also copies the files to my NAS (which is then backed up to the cloud).

Nowhere in that process do I ever delete anything.
