DST Short Test Failed
- If a DST Short Test fails on your computer, and you receive an error message or log entry that reflects the failure, this is likely caused by a failing hard drive. However, certain software will also cause the DST Short Test to fail. McAfee and other anti-virus programs may cause the DST Short Test Failure error to generate. Other corrupted applications may also throw the error. Re-install the anti-virus program, or return your computer to an earlier point in time with System Restore.
