This sentence makes alarm bells sound for me - like you're not
telling us something - why do you say "but"?  Surely, if you
mounted it read-only, then copying the files just works.  No ifs,
not buts.

Did you use 'cp' or some other command to copy the files (e.g. tar, cpio, etc)?

Check the system flags of those files with:
	ls -lo
and read
	man chflags

For example:

	#####	create a protected file from a normal one and fail to change it...

# ls -lo fubar
-rw-------  1 root  wheel  - 259 Apr  7 22:48 fubar
# chflags schg fubar
# ls -lo fubar
-rw-------  1 root  wheel  schg 259 Apr  7 22:48 fubar
# chmod 644 fubar
chmod: fubar: Operation not permitted

	#####	make it an unprotected file and change it...

# chflags noschg fubar
# chmod 644 fubar
# ls -lo fubar
-rw-r--r--  1 root  wheel  - 259 Apr  7 22:48 fubar

> Logged on as root: "chmod 777 .." just gives an "operation not supported"
> error message

If the above fails, check you're in the right (FreeBSD, not Linux) partition?
