How to fix invalid content in journal error?

Running Repair Disk in Disk Utility stated that the Volume was Repaired Successfully. However, the volume still will not mount and shows the same error message when performing another Verify Disk. Please help!

What is invalid content in journal error?

Invalid content in journal error is an error report of HFS+ file system in Disk Utility. The journal on the hard drive is a place where the system stores information before altering the contents of the drive. It is used to roll back to the previous status of hard drive when an operation fails or file system goes wrong. The journal lowers the probability of data corruption due to sudden power failure and inappropriate operation.

When a hard drive goes wrong, the Mac operating system will attempt to read its journal to check and repair the hard drive before mounting it. But if the journal is corrupted, the above problem will occur and invalid content in journal error pops up.
