hm, AFAIK ext3 is only aware of the "block-size" which can be 1024,
2048 or 4096 bytes per block. I'm not sure what this "32 Mb (Megabyte?
Megabit?) sector size" might be...

If it's really the block-size you meant: no, it's not possible to change
that without reformatting. The best you could do is to make a fresh
backup, mkfs.ext3 with the right block-size, then play back the backups again.
