No Bob, the FORMAT command does not lock out bad sectors. Personally,
I have wondered if the "verify" operation that the FORMAT command does
really works either since some of those horrid Tan floppies :-) will
Format & Verify and still come up with errors. Through some judicious
hacking I was able to write some code that would put "bad" sectors 
into a file but even that can't be made invisible because AmigaDOS'
dir command always lists out all of the files on the disk. My less than
perfect suggestion is to use 'defect free' floppies. Which means buying
DS ones even if you believe SS ones are Ok, and sticking to Sony's even
when Brown disks are cheaper.
