The biggest joke is, however, that the products issued by SanDisk itself after a certain number of failed attempts at writing in a read-only mode that can not be reset (even not with hdparm -r0)!
That's what happened in my case, that I can take the stick in the round tray, before he has ever seen data.
Unfortunately, I've only encountered this behavior as it was too late, so that my last SanDisk product was then.
