Great, in addition to easeus partition manager, also aomei partition assistant and gparted are both ok for partition management.You may delete the recovery partitions but first you must burn a set of recovery dvd's. (You should already have done this anyway!) The recovery partition is your only means of recovering your system in the case of a catastrophic disk failure or other serious problems which may render your system unbootable. You may also need to run a recovery if you ever decide to sell the machine on. Having burned a set of recovery disks make a second copy and keep them in separate places (no I'm not paranoid - I had just too many experiences of desperately need to run a recovery only to find a crc error on the optical recovery disk! Once you have done that use something like easeus partition manager (free download) to delete the recovery partition and reassign the space as required.
