backblaze(or any large storage provider) is never going to recover data from a failed storage drive. Their whole value proposition is that they are designed so they don't need to. In fact if I remember correctly, backblaze does not even try to replace failed drives, they wait until a rack unit ~ 60 drives degrades to given amount then replace the whole unit. Fun fact, one of the surprising differences between consumer grade drives and enterprise grade drives is the firmware in the enterprise drives is designed to fail fast. The theory being a consumer drive is probably the sole unit and should probably give every effort to limp along, to give the user a chance to get the data off. While an enterprise drive is probably part of a redundant array and should die quickly so the rebuild process can start as soon as possible.
