[comp.sys.mac] Disk directory failure - help!

usenet@jade.BERKELEY.EDU (USENET Administrator) (12/12/86)

I would appreciate some help and advice on what to do when a disk's
master directory goes kaput. This has just happened with a
double-sided disk with a lot of Overvue files on it (Mac+, HFS). 
The disk is now completely unmountable, and only FeditPlus will
even recognise it, and then only as a volume.
	
I know I can go through with FeditPlus and try to copy each file 
sector by sector, following the file tags, but whatever caused 
the failure may presumably have corrupted a file or two, and 
the process is very laborious in any case. Any shortcuts?
	
Directory failures seem to have happened quite a lot recently 
(though the previous ones just involved a bad downloaded file, 
and once that was deleted (or had its bundle bit unset) all was 
well again), so a relatively quick fix would be nice to know.   
It also seems to me that Overvue (v.2.0) is pretty buggy (failures 
to refresh the screen after using DAs, general crashes etc.) - 
does anyone else have this impression?
