How can I tell Amiga DOS to mark a track on a floppy disk "allocated"?

My friend has some floppies with errors on them and asked me if I knew how
to tell DOS to "skip over" the bad tracks.  I had an ol' C-64 years back,
and remembered (not too fondly, at that :^) getting into a full-screen
"disk editor" and manually marking off block as "allocated" in the BAM
(Block Allocation Map) on the directory track sector 0 (what was that, track
18 or something like that?  Does anyone out there remember that old stuff?)

For myself, I would just scrap the disk and use another (what, $.39?), but
my friend wants to still be able to use that disk.

Would DiskSalv or some such utility "repair" the disk by marking-off the
bad section of the disk????

Please forgive my naivity (sp?), but I have only had 1 of my floppies ever
go bad on me (knock on wood!), and it was actually on an MSDOS machine at
the time (yuk!! :( )

Please respond by e-mail, or a posting, for maybe some others out there would
also be interested in this.
