I think the ‘1’ in the warranty column means that IF there are problems with that attribute, THEN the drive is valid for warranty. However, your drive’s values seem OK:
Raw Read Error Rate: Value 200, Threshold 51, Worst 200
Reallocated Sectors: Value 200, Threshold 140, Worst 200
Spin Up Time: Value 135, Threshold 21, Worst 135
As you can see, none of the attributes have dropped below their given threshold. The first two attributes are still at 200, that’s the initial value of new drives. Spin up time has degraded a bit, but that’s probably nothing to worry about. My drive has a spin up time of 172 and never had any problems with it.
