Quite possible. I recently had a similar problem - stick went
to "no write" mode after having multiple fsck errors and system
crashes, including damaged binaries...

Run fsck manually, two or three times. Also try to re-initalize
the file system. Also perform a dd or tar test with the stick.
If any test fails, it's designed to be thrown away.

Any mount operation (except "mount -r") will intendedly (!) fail
if the file system is not in a clean state. So performing

	# fsck -yf /dev/da0

is needed, as mentioned maybe multiple times.
