I understand the English is not your first language, but there is too little detail in your posting about the exact error messages you have seen, the exact testing that you have done so far, the history of the drive etc. etc. for efficient diagnosis IMHO.
The messages from the LLF Tool suggest possible write errors after approx 147GB, but on its own, those messages are inconclusive, as they can have multiple possible causes (not only a drive fault can cause them).
You don't care about the data on the disk (since you are trying to overwrite it), therefore you could run another utility to try to erase the disk e.g. WD Data Lifeguard can perform a write-zeros operation (as well as performaing a read scan and displaying basic SMART data) - see this page for an example link:
