Linux does have software raid, but I've no idea if this is what your
device uses, or if your device even uses Linux.   The software raid in
Linux is not part of EXT3, it is implemented with a different set of
tools, although the filesystem being mirrored may be an ext3

Remember, EXT3 is just a filesystem, it is implemented on many
operating systems, Linux just happens to be the most common place
you'll find it used.  I don't think the term "Linux EXT3" makes sense.
 There's Linux, and there's EXT3, but the two are not dependent upon
each other :)

You do not need to format the drive to look at the SMART information.
There are almost certainly tools for looking at the SMART data in
Windows, but I'm not familiar with them.   These tools should not
require any formatting of the disk.
