我想啊想，有这么几种吧。
hd-copy simg diskimage dosimg eim
先讲一讲经典的hd-copy！
hd-copy不用我说是什么吧。太经典了。全称应该是high-density-disk-copy高密磁盘复制器。因为3.5寸盘被称为高密磁盘。
用法很简单。界面也很简单，支持鼠标和键盘操作。
在dos下键入文件名（一般地，我们都把它的文件名改成了hd.exe），回车。
不出错的话，就会有一个简单的图形界面出现:
hd主画面：

拷贝功能：
1.将欲拷贝的盘插入软驱，按R键，或将光标移到Read一行按回车读盘。
2.读盘完毕，换上目的盘，按W键，或将光标移到Write一行按回车写盘。
格式化功能：
1.将欲格式化的盘插入软驱,按F键，或将光标移到Format一行按回车
出现格式化菜单,选中一种格式,按回车,开始格式化目的盘。
读写文件功能：
1.put to file 是把读到的整张盘写成一个文件,以IMG为扩展名。
2.get from file 是把IMG文件读到内存区,然后运用WRITE功能写到目的盘中。
退出功能：
1.按Esc键，或键入E键， 或将光标移到Escape一行按回车
使用中如果问你(yes/no),键入Y或N即可。
这是我用Get from file功能把一个IMG文件读到内存区,然后运用WRITE功能写到目的盘中
，再读目标盘后形成的图像。

用hdcopy来格式化软盘或是来复制软盘速度很快。用来制作IMG映象文件和释放IMG映象文件到软盘中也很好用。
此外还有一些特殊的用法：
1。清洗磁头。sepcial menu里有一项是清洗磁头，效果还不错。
2。挽救损伤的软盘中的数据，由于hdcopy读数据的方法比较特殊，纠错能力又强，而且读不出的数据还会自动填充。能最大限度地挽救数据。我怀疑后面出的badcopy是不是就是受他hdcopy的启发。
3。格式化软盘，使零磁道损坏的软盘起死回生。有时挺管用的。
4。在special menu里有查看目录的子菜单，有时你运行hdcopy时想看看插进去的软盘的内容，这个菜单就能帮上忙了，（因为DOS一般来讲是单任务操作系统，你不会想退出hdcopy后再用dir来查看软盘里的内容吧。）这样，你不用退出hdcopy就能确认你放进去的软盘是不是你想放进去的那张。
这是特殊菜单中的查看内存使用状态（memory statisticc）时的图，可以看出我们的HDCopy用的是XMS！
这是特殊菜单中的清洗磁头（use clearing disk)的功能时的图。
不足：必须有真实的软驱，至少要一个才行。它的操作都是针对真实的软驱而来的。如果你没有软驱，那这个软件就基本没用了。就象俺一样。俺就不用hdcopy了。
没有软驱怎么办？就要由下面的软件出场了！下一个是eim(easy image???),敬请期待。
I think, there are several types.
hd-copy simg diskimage dosimg eim
Let's first talk about the classic hd-copy!
hd-copy doesn't need me to explain what it is. It's too classic. The full name should be high-density-disk-copy (high-density disk copier). Because 3.5-inch disks are called high-density disks.
The usage is very simple. The interface is also simple, supporting mouse and keyboard operations.
Type the file name under DOS (generally, we have changed its file name to hd.exe), and press Enter.
If there are no errors, a simple graphical interface will appear:
hd main screen:
********************************* **********************************

********************************* * Verify destination Verify destination disk *

Copy function:
1. Insert the disk to be copied into the floppy drive, press the R key, or move the cursor to the Read line and press Enter to read the disk.
2. After reading the disk, insert the destination disk, press the W key, or move the cursor to the Write line and press Enter to write the disk.
Formatting function:
1. Insert the disk to be formatted into the floppy drive, press the F key, or move the cursor to the Format line and press Enter
The formatting menu will appear, select a format, press Enter, and start formatting the destination disk.
Read and write file function:
1. Put to file is to write the entire read disk into a file with the IMG extension.
2. get from file is to read the IMG file into the memory area, and then use the WRITE function to write it to the destination disk.
Exit function:
1. Press the Esc key, or type the E key, or move the cursor to the Escape line and press Enter
If it asks you (yes/no) during use, just type Y or N.
This is the image formed after I used the Get from file function to read an IMG file into the memory area, then used the WRITE function to write it to the destination disk, and then read the target disk.

Using hdcopy to format a floppy disk or copy a floppy disk is very fast. It is also very useful for making IMG image files and releasing IMG image files to floppy disks.
In addition, there are some special uses:
1. Clean the magnetic head. There is an item in the special menu to clean the magnetic head, and the effect is not bad.
2. Salvage data in damaged floppy disks. Because the way hdcopy reads data is relatively special, the error correction ability is strong, and the data that cannot be read will be automatically filled. It can salvage data to the maximum extent. I suspect that the subsequent badcopy was inspired by his hdcopy.
3. Format the floppy disk to bring back to life a floppy disk with a damaged zero track. Sometimes it works.
4. There is a sub-menu to view the directory in the special menu. Sometimes when you run hdcopy, you want to see the content of the inserted floppy disk. This menu can help, (because DOS is generally a single-task operating system, you don't want to exit hdcopy and then use dir to view the content of the floppy disk.) In this way, you don't need to exit hdcopy to confirm whether the floppy disk you put in is the one you want to put in.
This is the picture when viewing the memory usage status (memory statisticc) in the special menu. It can be seen that our HDCopy uses XMS!
This is the picture of the function of cleaning the magnetic head (use clearing disk) in the special menu.
Disadvantages: There must be a real floppy drive, at least one is required. Its operations are all aimed at real floppy drives. If you don't have a floppy drive, then this software is basically useless. Just like me. I don't use hdcopy.
What if there is no floppy drive? Then the following software will come on stage! The next one is eim (easy image???), stay tuned.
