Which command causes the errors?  The mode select or the format?

If it's the mode select, there's definitely something weird going on.  If
it's the format, you probably haven't set the timeout long enough.

It would be helpful if you could send a stack trace from the panic.

Hmm.  Well, if the format has been able to go all the way through after you
changed the sector size, and it still thinks it has 520 byte sectors, yeah,
you may be out of luck.
