It seems to me that the Checkpass does that if there are too many bad
sectors on the disk. (There may be other causes too.) I'm not sure how
to deal with such a problem. I have an RD53 with too many bad sectors.
The format hung even after I changed all the appropriate parameters so
that there were sufficient replacement blocks. (You know, this really
makes me question my belief in the immortality of RD53s :-)

I think that the ID jumper on the drive has to be set to 3.
