Paragon Partition Manager 9.0 is an excellent one. You can create a bootdisk with it and do it out of Windows for max safety.
I recently repartitioned my RAID5 array with it and no problems here

Can't comment on the tool - most pretty reputable ones are fairly safe - but I woould disagree with the statement

Anything as fundamental as a disk partitioning should not be done on a mounted disk. Many (if not all) partition managers, even if they are launched from the windows environment drop out of windows into a DOS (or other OS) mode for the actual re-writing and resizing of the partition table. I would expect (and hope) that partition manager does too.
One of the things (to my mind) that makes Gparted so attaractive is that the target disk is not mounted at all - by booting off a CD and running the application completely off the target disk gives (to me) an extra level of assurance. That is not to say that other tools are inferior or carry any greater degree of risk. Messing with the partition table is one of the highrerrtisk computer ioperations (which is why all tools recommend backing up important data before you start )
(And before anyone asks, IMHO the riskiest operation is re-flashing the BIOS - although not endangering any data, does run a risk of making the mobo un-bootable without hardware repairs).
