It's not hard to find tales of woe concerning modern cards in
phones and cameras. I'm sure those devices have much better
procedures for handling errors that I have

If error detection and correction is behind the controller and
the controller isn't working properly, can I even do anything ?

>From the wiki link

"To avoid the read disturb problem the flash controller will
typically count the total number of reads to a block since the
last erase. When the count exceeds a target limit the affected
block is copied over to a new block".........

So, if the error occurs before the target limit, then what ? How
does the controller know that the block is "affected"

If the block read returns a Data Error Token, then surely that
means the data is corrupted, hasn't been fixed and is therefore
lost ?

Talk about chasing rabbits down holes
