You have not specified for which Coco OS. If you are attempting to track 
a file in OS-9, use dEd. It won't automatically give you the requested 
information but with the tech section of the manual will permit display 
of the needed disk sectors.

I sell a raw disk editor for Disk Basic which looks and feels much like 
dEd. It will link to a file, follow the FAT, and display only those 
sectors assigned to the file. However, the best use per your question is 
that described above. Use the tech information for Disk Basic disk 
structure along with the program to repair the FAT table in T17S2.

My guess is you are just interested in OS-9. It should not be too 
difficult to write a program to open a directory, find the required 
file, read the directory entry, and trace the file descriptor links 
while compiling a table of data.
