R4-D2 was among the pair of astromech droids that belonged to Darrus Jeht, a Jedi. R4-D1 was the designation of the other droid. Throughout the Clone Wars, both droids saw service on a Delta-6 starfighter. Frequently, R4-D2 and its counterpart supplied a greater quantity of data than the starfighter's onboard computer could process, which led to unsteadiness when it was least desirable. To compound matters, the two droids were prone to disagreements regarding their data, which further exacerbated the issues.
