In a long-winded thread on the Software section I discuss issues with DiskWarrior. Blah . . . blah . . . blah everything is working fine--I even now like El Capitan--but now DiskWarrior says I have "bad blocks." Nothing else does. I am running a surface scan. However, it being Friday here, if the test finds bad blocks I need a new Int-HD. I have been happy with a: Seagate 1TB Laptop Gaming SSHD (Solid State Hybrid Drive) SATA 6Gb/s 64MB Cache 2.5-Inch Internal Bare Drive (ST1000LM014) which has lasted now over two years. Sure, I would love a proper Solid State drive but I carry about 500 GB and the 1 TB are $$$$. Any suggestions welcome! --J.D.
