A fragmented disk will not stop you from resizing a partition, Avalon.

It might take a bit longer to do so but it certainly will not prevent you from doing so.

A partition in use, on the other hand ... well.

That's why I always use a bootable partition manager to do the "dirty work" (after I back up, of course).
