Yes, that's what I mean, you have to understand how ext3 works to mess with it raw. With the bits of it you've overwritten now, it probably needs a reformat to be valid ext3 again.
Do you need to use ext3? If not, I'd reformat it with /sbin/fsck.msdos -F 16 filename/sbin/mkfs.msdos -F 16 filename as the MSDOS filesystem is far, far simpler: just a big table, instead of a tree.
You might find the hexdump utility handy to show you what data you should expect to find in what places. Here's part of a hex dump of a flash drive I had lying around:
If you want to use a proper Linux filesystem, try ext2 instead of ext3, it's pretty much the same as ext3 but with a lot of journalling fluff cut out.
Theselinks are good starting points on FAT and ext2.
