Ashampoo's author does not understand Seagate's counterintuitive SMART attributes. Therefore his/her interpretations of the data should be viewed with caution.
See
http://www.users.on.net/~fzabkar/HDD/Seagate_SER_RRER_HEC.htmlThe Raw Read Error Rate is quite OK and is within the normal range for your model. I don't understand how the author arrives at a "status" of only 54%.
The Seek Error Rate is actually 0 and represents a perfect score, not 70%.
The End-to-End Error Count has fallen below its threshold level, so technically that would mean that the drive has failed. However, I have yet to see any case where this error has been a genuine problem. In fact I suspect that all such errors are automatically corrected.
