Released by Basement Boys Software and Written by the one and only Mike J. Henry. Great disk editor, you need it, get it, be happy!

Another Disk Editor 64 -The usual disk doc with options to change colors, reset drive, search for a string (slowly), fill an area, get a checksum, and read drive memory, among others.  mach language for speed, novel display.  the command menu is not on screen, but can be viewed by pressing '?'.

BLOCKBUSTER is a disk sector editor program, ala "Disk Doctor". In addition to reading and writing standard sectors directly to the disk, BLOCKBUSTER is able to read information 'hidden' beneath most errors, and can read tracks 36-40. BLOCKBUSTER also also has a number of other useful features. BLOCKBUSTER is intended for use with an unmodified 1541 drive. It is presently incompatible with the 'FLASH' 1541 ROMs, but IS compatible with the FastLoad cartridge by EPYX.

C64 Disk Patch for the Commodore 64 / 1541 floppy drive - Couldn't find much information on this track / sector editor, but it is pretty self explanatory with a built-in help menu.

Disk Buffer - this program is similar in purpose to the disk doctors, but the implementation is quite different.  a disk block is read into c64 ram and examined from there.  it may have some good  features, but will be confusing to anyone used to the "disk doctor" format.

Released in 1985 by Tim Gerchmez. This is an extremely nice disk editor for the 1541. It is full featured and easy to use. The built-in help is complete and concise. Add this to your tools arsenal.

(c)1986,87 Written by G. Brandt & A. Wellie - Disk Demon, the best disk editor ever (not my words).

Disk Doctor (C) 64 (also known as Sector Doctor) - this implementation of disk doctor has all the features of the original.  in addition blocks can be chained and then scanned forward and backward.  basic tokens and ml op codes can be identified and "words" can be displayed in hex or decimal.

Pickell/Phillips Disk Doctor by two canadian programmers of moderate fame, this disk doctor in mach language for speed adds the dos type and disk id to the standard display.

This program was released to the public by Solidus International Corp. - Disk Doctor 64 is a track and sector editor that is easy to use and fully featured.

The Disk Doctor for the C64 is one of the most powerful disk utilities that you will ever own. It allows you to not only view but change any byte of data stored on any of your 1540, 1541, 1570, 1571, 4040 and compatible diskettes. Documentation on the disk is very extensive.

This version of disk doctor has many new features.  it will copy blocks to other disks, work backward through the last three blocks viewed, and scan by blocks or tracks forward or backward continuously if desired.  the instructions program details these features and those found in the standard program as well.

Disk Doctor v3 was written by Kevin Pickell with Mods by Larry Phillips.  Disk Doctor is a track and sector editor with the power to royally hose your disk if you don't know what you're doing.

Disk Editor is a simple program to display the track and sector hex data.

Written by Douglas McLaughlin, Disk Editor v0.75 has a tremendous amount of functionality for editing a disk at the track/sector level, but on of it's most unique features is that it works with IEEE drives like the SFD-1001 & others. It also works with standard CBM drives and CMD drives. Docs are on the disk. Another bonus is the BASIC and Assembler code is also included.

Disk Fiddler is a neat little BASIC program that lets you view, edit and even save disk blocks back to disk. I couldn't find any information on the author, but this came from the May 1985 PCUG monthly disk.

Disk Frisk by Jeff Johnson, released in 1985.  This is a pretty solid little utility for doing all kinds of low level stuff with a floppy disk.  There is sector editing, un-scratching files, lock/unlocking of files, file tracing and more.  This would be a good utility for your toolbox.

Disk Hacker v1.0 by David Chiles (August 28th, 1985) - There's certainly no shortage of utilities that let you edit the contents of a track / sector on a disk, but I kind of like this one, because it not only has built-in documentation,  butm it can also handle several tracks / sectors worth of data at one go.

Cracked by The Great Diablo. This seems like a really nice disk editor, but I can't find any help screens or docs.

Written by Sean Godel. Disk Surgeon is a track & sector editor. A few of the features include: Read data from, edit and write to disk, analyze disk errors, write errors 20,21,22,23,27,& 29 to disk, read data under errors or erase errors, format a single track with any ID and much more.

Error Editor by Star Software released in 1985 - If your floppy has an error or you want to add one, this is the tool for you.

(c)1984 by H.Staeudel & A. Dripke. This program is quite advanced and has a few features I don't commonly see in other disk editors such as the ability to dump track & sector information to a printer and the ability to work with drive buffers and cpu memory.

Facsimile Disk Editor - disk doc with s hex/screen code sector display, search for string, change dev & drive number on two drives, two drive copy, bam display showing sectors used by each file.  dir, format, bulk erase, & speed check.  error message summary. mach language for speed.

GDM Geos Diskmonitor v2 by H. Luyten (1987) - Found this interesting track/sector editor that apparently came with a German book called "C64: Everything About Geos".  Besides the neat sprite hunting feature, it also has a special value to GEOS users as quoted from Heiko Herrmann, it "is aware of the special file structure format of the VLIR files, so the "F5 Directory" mode will be able to jump you to the actual pages of the VLIR files."  

Here is a thread over at Facebook if you want to add any further details you may know about the program.

Message Master written by Vader is as far as I can tell a fancy interface for a program that does little more than change the disk name and ID of a 1541 floppy.  Don't get me wrong, it's still cool, just a little overkill ;)

N.U.R.S.E. is a comprehensive diskette sector editor written for the Commodore 64* and the Commodore 128* computers. Designed for ease of use N.U.R.S.E. includes many commands you only dreamed of having in other sector editors for Commodore computers. Extensive docs are on the disk.

Broken by Dr. Chip - Reconnaissance is your standard sector editor but with nice printer support. It also supports drives up to 11 and has built in drive renumbering.

Here's an interesting little utility written in BASIC for the Commodore 64 that will let you recover from disk error 23 or 24, according to the remarks in the code.  Basically it lets you follow the track/sector chain of a program and edit the raw data, which it will then write back to the disk.  There is also printer output if so desired.

By The Deacon - Satan's Seed is a 1541 sector editor with a few other additions thrown in. Docs are built into the program.

Hmmmm, let's see.... it's a sector editor.  Don't know anything more about it.  Seems to be good at what it does ;)
