A lost soul brought me a damaged Mac 1440K floppy disk with two bad sectors.
 This disk contained an EXCEL file with 5 years of blood sugar data (the last year unbacked up)
 The verify funtion of Mac Tools by Central Point reported of both sectors "-71 error,
"couldn't find a data header mark".  I have attempted recovery with SUM II,
1st Aid, and Copy II/Mac Tools Deluxe.  I'v run out of ideas.  There are
a few other options that operate directly on the damaged disk, but I prefer
not to use the original disk.

1)	Does anyone know of a mac program that can make a bit image of 1440K
disk?  Central Point's software does supports bit images only on 400K and
800K disks.

2)	Does anyone know of recovery software that dan repair a bad sector
header on a 1440K disk.  Central Points Track Editor only works on 400K and
800K disks.
