Right, that was my concern too. I guess what I wasn't sure of is
whether an erase failure is almost always (barring driver issues) an
indication of a bad block, or whether, like writes, it can be a
temporary glitch for which retries make sense. Since in my case it
turned out to be a driver issue, I still don't know the answer to this
question, but it is now less pressing.
