Suppose it's just an SD card or SSD with data no longer needed but has been left without power for ages. Then you try to erase it (by writing 1s (or 0s) to all of it) - will it work for new data written after that?  I suppose you'd have to "format" (repartition etc), but will it then be OK? ("format" used to be something else, with disks it meant writing sector stuff, timing info etc, not really relevant for SD / SSD) John
