White box testing requires knowledge of source code. It can be done at coding level.
Where as black box testing doesn't require the knowledger of the code. white box testing helps in removing the extra lines of code, which can bring in hidden defects.
White box testing fails to detect missing functions. In case of black box testing any non-technical person can do the testing. Black box tester need not have the detailed functional knowledge of the system under test. Source: CoolInterview.com

White Box testing:
Advantages
1) more code coverage
2) more error can be found earlier during the development process.
3) The whitebox testing could start in the early phase along with softwrae development.
4) Just a main module from developer is enough to start to test by using stubs.
5) helps gving more stable build

disadvantage:
1) more time consuming to develop test cases as it involves development effort
2)often new architecture need to be designed to suit your testing needs.
3) Testers need to be involved in requirements , software design document review also.

Black Box:
Advantages:
1) testers need not know the softwrae design of the SUT
2) requirements are enough to develop test cases
3) Black box tetsing is usually done manual except

disadvantages:
1) more time required to test each test case and verification results
2) less code coverage
3) some scenarios can be eliminated due to human error or ignorance of the system. Source: CoolInterview.com
