USB booting :: booting from SanDisk cruzer micro

If I install DSL on to my SanDisk "cruzer micro" USB drive, will that erase everything else already on it?

I'd like to use the USB drive for things other than DSL booting. Is that possible?

Thanks!

yes - if you use the standard methods.
yes - depending on what you want to do with it.
