How to determine what partition is still not formatted?

Thanks.

Hadn't tried that, but it doesn't look like any more information than I 
can get from fdisk. E.g. parted's 'print' shows the partition type, but 
doesn't actually test whether there's a formatted file system there 
unless you're doing a file system operation on it. And it feels safer to 
me to just try and mount a partition temporarily, and read-only if you 
really want to be careful.
