The result keeps Yorkshire at the top of the CGU NL First Division with a 100 per cent record after four games.
Set 133 to win on a used pitch which had plenty of life for the pace bowlers, White and David Byas made light of the task with a stand of 115 in 16 overs.
White hit two sixes and nine fours off 48 balls and he was particularly severe on Simon Renshaw who was collared for 30 runs in two overs. Byas, as usual playing strongly off his pads, finished unbeaten on 46 with eight fours from 50 deliveries.
Darren Gough made a quick return to Yorkshire's ranks after the World Cup and broke through in his third over when he had Giles White caught by Richard Blakey for three.
Nasser Hussain returned to the scene of England's demise with a match- winning 81 from 114 balls at Edgbaston.
The Essex Eagles captain set up a formidable score of 238 for 5 before Ronnie Irani took a League-best 4 for 13 to send Warwickshire Bears to defeat by 129 runs.
Irani's clutch of wickets in successive overs instigated a collapse to 109 after another failure for England's recent outcast, Nick Knight, who was bowled by Ashley Cowan for seven.
With his own kit still at Chelmsford, Hussain batted in Jamie Grove's No 12 shirt and later took two catches while wearing the No 7 of Paul Prichard. He shared an opening partnership of 124 in 27 overs with Darren Robinson (53) and Stuart Law contributed 48 from 37 balls.
Trevor Penney's unbeaten 32 was the top score by Warwickshire in their second home defeat in the new 45-over format.Reuse content
