My Passport Reliability after DLG Repair

I have a 1TB My Passport that was showing signs signs of some sort of corruption. I got all my files off. Ran the full array of WD and DLG Tests.  It failed both the Quick and Extended tests even after a reformat.

I executed Write Zeros using DLG and now it passes all tests.  Can it be considered reliable now or is this the beginning of the end?

I jumped the gun.  It did not pass the extended test.  Error 8: Too many bad sectors.  RMA time I guess.

Absolutely go for the RMA. Bad sectors should definitely qualify for replacement under warranty.
