DD is a very important disk mirroring tool under Linux and UNIX, and now it has a version of Windows. Although DD is a command-line based application, the operation is not convenient, but the command line application advantages are not available to the graphics program, for example, want to do a bulk image of the hard disk, if the graphics interface program processing, can only wait to do one more, but with the command line of DD, The next batch command can be executed in bulk.

DD for Windows executes in the following format:

DD [Bs=size[suffix]] [Count=blocks[suffix]] if=file of=file [Seek=blocks[suffix]] [Skip=blocks[suffix]] [--size] [-- List] [--progress]

which

BS represents the size of the buffer block when mirroring, it is usually recommended to set a larger, such as 1M, 10M, etc. (unit available: C for Byte, W for two words, D for 4 bytes, Q for 8 bytes, K for 1024 bytes, m for k*k bytes, g for k*k*k bytes), default to 512 bytes

Count represents the total number of mirrored blocks

The device file path that represents the mirror source and the mirror target, respectively, of the

Seek indicates how many blocks are skipped on the back part of the object, which is the target file at the time of the backup, and then start writing

Skip indicates how many blocks were skipped on the back of the If after the backup and then the backup starts

--size indicates a checksum of the source device reading to avoid errors such as Io dead loops

--list indicates that the available disk (partition) device files are listed, which are specified in if and of, these device names

--progress indicates mirror progress

Example:

To mirror a floppy disk:

DD If=\\.\a:of=c:\temp\disk1.img bs=1440k

Mirroring the hard drive

First use DD--list to find the device path to mirror: \\?\DEVICE\HARDDISK1\DR5

Then execute:

E:\>DD IF=\\?\DEVICE\HARDDISK1\DR5 of=r:\aa.img--size
