Thanks Bertrand, Warner, & Tomek,
I wonder if we might append hints somewhere, maybe in man camcontrol ?, eg
If USB memory media goes from read-only, without a physical switch, eg dmesg:
(da0:umass-sim0:0:0:0): SCSI sense: DATA PROTECT asc:27,0 (Write protected)
it has probably been written too often, worn out, &
all spares exhausteare d in the Flash translation layer (FTL)
https://en.wikipedia.org/wiki/Flash_memory_controller#Flash_translation_layer_(FTL)_and_mapping
camcontrol defects da[0-9] -f block
# Old 32-bit block list is not implemented in Flash drives
Cheers,
