I spent some time on another thread on this site where a guy was having erratic problems with his SSD. He used Scannerz on it which eventually confirmed that the SSD, which isn't that old, had developed confirmed bad sectors. He also later confirmed that he had cable problems. He wasn't exactly the luckiest guy on Earth. No one else chimed in on the post, I suppose because it went on forever, but in any case, I have to wonder, why didn't the SSD correct the bad sectors and relocate them itself. I thought they were supposed to do this. I know that an SSD can develop bad blocks or sectors (I'm not sure what the right term here is) that eventually suffer from "write depletion" meaning that the SSD can no longer write to that block/sector after so many writes have occurred. I thought that this was technically a "bad sector." Scannerz is a read-only tool (at least I think it is) but it's also supposed to follow sector re-maps. We've used the product with hard drives since it was released with great success, so I have to assume that a "bad sector" being reported by Scannerz means it can't even read it. I am seriously, totally confused about this. If an SSD can develop bad sectors or blocks or whatever they're called that can't even be read, why are they any better than a hard drive? Hard drives typically need to be subjected to some type of external problem, like impact during a read/write operation to develop bad sectors, and yet an SSD is impact resistant. So why are the bad sectors developing? I'm growing ever more cynical about SSDs. I swear if you go from Mac tech site to site, you'll see things like "The SSD just lost all my data", "The SSD can't write anymore", and even "The SSD is developing bad sectors." This sounds to me like a not ready for prime time product. I have to admit, I don't know a lot about SSDs which is why I'm posting this question. There must be someone on this site that can clarify bad sectors on an SSD vs depleted sectors on an SSD, and hopefully tell us why and what the odds are of developing a genuine bad sector for no apparent reason. By the way, the poster of the thread I was following is probably going to send his in for warranty replacement. Will warranty replacement be honored? Thanks!
