heh ALL of them are rather stingy with warranty claims. Unlike before where they used to send you a drive that would work, these days they turn down claims for any and all reasons. I sent in a rather new drive that developed errors, got a refurbished one back, would not have minded so much but it was a degraded one without NCQ and used for an year or more as it had scratches and dents. Another one which supposedly had a 5 year warranty I sent in got another certified drive that developed errors in less than 100 hours of use. Another one they did not even bother sending back other than to mark it as warranty failed because I updated the firmware after it got errors. Since there is no one to contact, I never did receive a reply or the drive back.. I really got miffed about the brand new drive being replaced by a lesser used model without even the same functionality. I dont know if places like backblaze ever gets back decent drives.. But form my own experiences, the drives that come back are unreliable and degraded.. Which means you can not just replace the failed drive. They may work fine, but often you dont know.. A decade ago they would send back new drives in many cases. I think the refurbished drives also have a reduced warranty of like 30 or 90 days. Mine said 30 days even though an year remained of the original warranty.
