I've got Torch somewhere... It's essentially:
 
Sectors:
000-015 Directory
016-017 Allocation map
018     Test pattern
020...  Data
 
Directory:
000-001 Allocation block
002-003 File length
004     User number
005-00C Filename and user attributes in b7
00D-00F Extension and system attributes in b7
 
Logical sector numbers are a bit odd, as CPN assumes there are 16
sectors per track, but uses ten sectors per track in FM, and marks
the final six of each track as "unusable" in the allocation table.
