And that theory makes sense. After you pointed out that my bumpy thing was due to it being a SMR drive, I found out that several drive makers were not telling people they were getting 2nd best drives. I read about a LOT of people who use RAID and such getting hit hard with this. Some seem to have taken basically new drives and created a doorstop pretty quick. I hope it was within the warranty time so the maker can foot the bill for their deception. It seems that consumers learned a lesson. I'm not sure about the makers but at least now they do make public what drives are SMR so people who have use cases that result in dead SMR drives can avoid buying one. I'm just glad to know what I ordered is what I expect. No unpleasant surprises. I hope. Dale :-) :-)
