Greetings,
The initial results of your testing are not good. I’d recommend that you back up your data (now) as a precaution. It is possible for a drive to fail a quick test, but pass the extended. If you encounter the same error two or more times after testing, I would RMA or replace the drive. If you wish to test the drive further, perform a low level format (Write Zeros), selecting Full Erase when promted. If the drive errors again, you have a confirmed failure.
