Well, it says so on Cowon's website, twice. Sorry about your loss.

All data in D2 will be deleted, so please back up your data.

Backup any important files to your computer before upgrade.

If you upgrade from 2.57 to 2.59, you can omit the "0" folder and drop both "1" and "2" at the same time onto the D2 - that way the memory doesn't get formatted. This doesn't work with upgrades from earlier versions.
