Comment 32 for bug 484252

Just been bitten by this as well in Oneiric. The dialog does say "entire disk" but it's still very ambiguous. Primarily because on the main dialog, in the LABEL and CAPACITY columns, it gives the label and capacity for the first partition, rather than the entire disk. If THAT dialog said 320GB instead of 4GB, it would remove all doubt about what is about to happen.

I'm frankly amazed that this has been open since 2009, given that it can and has resulted in catastrophic data loss.
