File system just never formats the media, so of course they never
corrupt anything. Utilities mkfs.ext3 and the like do this instead. 

In fact, you can thing of UBI the same way - it does not format, there
is ubiformat tool for that. Then, there is one single exception - empty
flash. It is just very handy to be able to attach it without ubiformat.
You can consider this as an additional usefuls feature.

And UBI does manage somehow to not corrupt anything. So the question was
- why UBIL cannot?
