Read Error Rate
Frequency of errors while reading raw data from the disk. A non-zero value indicates a problem with either the disk surface or read/write heads.
Under the Assessment column for this category it says:
Then under the Value column there is:
Normalized: 50
Worst: 50
Threshold: 62
Value: 768612578
I think this means that it is basically dead. Thank you all and please correct me if I am wrong.
