Uh-huh. You overwrote the start of the filesystem (which typically
includes things like the root directory) with your PNG.

Run fsck on the partition and it will do its best to recover. Best

will appear in lost+found, where you can examine and (hopefully)
identify them.

Yes, and I'm sure it is. The redundancy in a RAID only protects
against hardware failure, though, not user error.
