Actually...they are not any more "sensitive" to being removed than
other solid-state-devices...which is to say they are NOT as sensitive
as you suggest.
Wait 30 secs or so.....THEN remove it....(just to "be-sure")

After successfully using my Rpi 4 B+ for a few months as part of my homebrew mobile manpack rig I decided to back up the SD card prior to installing a GPS dongle. I did a sudo shutdown -h now and powered down. When I stuck the SD card it into my PC it was blank, save for the volume label.
After failed attempts to recover the data, I flashed a new card, installed Hampi again, started reconfiguring Flrig etc., Then I decided to double-check the new card. I did the graceful shutdown before pulling the card out but evidently wiped that one as well at some point in the process. All files were gone but for a couple of text files and the volume label.
Subsequent online research indicates maybe I didn't let the pi shut down all the way before pulling the card. I did not know to wait for flashing lights after shutting down. However, I'm pretty sure I powered it down all the way after several seconds. After spending hours flashing cards and looking forward to the prospect of going back to square one yet again and then reconfiguring the software again, and hoping it doesn't happen a third time, I am thinking the pi may just be too fragile a system to rely upon for emergency/mobile comms. It seems crazy that the SD card should be so vulnerable to erasure simply by being extracted from the Pi.
At this point I am planning on just using the Toughbook that I was using as a keyboard/screen interface to host the software and cut out the Pi. It's a shame since I've invested countless hours in getting Hampi up and running.
Has anyone else had this experience?
