I don't give models that fail on me a second chance. Anything that isn't designed to be repaired needs to work at least until the warranty expires. There aren't that many moving parts in these drives and any flaws in soldering or connectors shouldn't be dismissed as anomalous as they are built in large part by machines.
What I can't excuse is the people that give something a bad review because they can't make it work due to ignorance or the inability of the vendor to deliver the appropriate product.
Unfortunately, machines are as perfect as the humans who made them. Every now and then there is a bad batch. Most of the time this is caught before the product hit the shelfs, but sometime is after the fact. “stuff” happens. Unlike popular belief, there are plenty DOA drives sitting on store shelves right now.
