I have to correct my former comment: cp --sparse=never only works with very
small files, e.g. 542 bytes.

(PWD=/home/kj/MyDrive)

$ /bin/cp --sparse=never ~/prj/kaese/cpp/Makefile .
$ stat Makefile
  File: ‘Makefile’
  Size: 542             Blocks: 2          IO Block: 4096   regular file

$ dd if=/dev/zero conv=notrunc count=1 seek=1 of=/home/kj/MyDrive/eio.test
1+0 records in
1+0 records out
512 bytes (512 B) copied, 0.00248944 s, 206 kB/s

But, with longer files:

$ /bin/cp --sparse=never ~/Tc7200.bin .
/bin/cp: error writing ‘./Tc7200.bin’: Input/output error
/bin/cp: failed to extend ‘./Tc7200.bin’: Input/output error

$ ll ~/Tc7200.bin
-rw-r--r-- 1 kj kj 26296 Sep  8 21:45 /home/kj/Tc7200.bin

I need to say that using tar, I can produce much longer files:
