I'm sure there are several candidates out there.
http://www.sydex.com/other.html once had info about Anadisk but
now it's gone. My hard drive had:
10/22/97 02:14p 122,783 Anadisk-2_07.zip
09/03/92 12:50p 78,502 ANADISK.DOC

Below is the section from the manual that describes their
file format.

The Dump operation writes a specified area of a diskette to a DOS
file. After selecting the Dump option from the Main Menu, the
diskette drive containing the diskette to be read, the range of
cylinders and sides to be written to a specified DOS file are
selected.
Each sector written to the file is optionally preceded by an
8-byte header record of the following form:
+------+------+------+------+------+------+----------+
| ACYL | ASID | LCYL | LSID | LSEC | LLEN | COUNT |
+------+------+------+------+------+------+----------+
ACYL Actual cylinder, 1 byte
ASID Actual side, 1 byte
LCYL Logical cylinder; cylinder as read, 1 byte
LSID Logical side; or side as read, 1 byte
LSEC Sector number as read, 1 byte
LLEN Length code as read, 1 byte
COUNT Byte count of data to follow, 2 bytes. If zero,
no data is contained in this sector.
All sectors occurring on a side will be grouped together;
however, they will appear in the same order as they occurred on
the diskette. Therefore, if an 8 sector-per-track diskette were
scanned which had a physical interleave of 2:1, the sectors might
appear in the order 1,5,2,6,3,7,4,8 in the DOS dump file.
After the last specified cylinder has been written to the DOS
file, AnaDisk returns to the Main Menu.
