All the more reason for them to be transparent, name the problem, remove the affected stock from sale, set up some kind of recovery and/or compensation service, and write off the loss. Otherwise "SanDisk" will mean "you have shit on your shoe" forever. In the storage space a brand has to mean "safe" or its dead.
Maybe they are still finding the edges of the problem. Maybe.
All I will say is: wait till it encounters a Scottish accent. Sigh
