Don't go away if you struggle to sync two external hard drives in windows 10.

How to sync two external hard drives in Windows 11/10
As described earlier, we present two tools for synchronizing two external hard drives. They include a command line tool and free
Let's understand how to sync two external hard drives in Windows 10 by using these two tools.
1. Synchronize two external hard drives with XCOPY command line
The XCOPY is a built-in command line tool available in windows 10. The tool permits efficient data sync from one external hard drive to another. However, it only allows one-way sync. It can also copy individual files or folders from one position to another. The tool is more versatile than the generic copy command.
For execution, you must open the command prompt window and run the command with the required parameters for syncing two hard drives. Here is the intro and detail of these parameters:
- Source>: It specifies the files and data you wish to copy. It consists of either a drive or a path.
- Destination>: It specifies where you want to copy all the source information. The destination name can consist of a colon, drive letter, file name, or any combination of the mentioned options.
- /e: This parameter authorizes you to copy directories and sub-directories from the source hard drive to the desired one. The parameter can also copy the empty directories.
- /d: This parameter only copies those data files from source to destination hard drives which have been either altered or newly added. That means that the copy data is unique. The files are not present in the destination files before the sharing.
- /c: This parameter is used for smooth sailing of the copying process. The transfer is carried out despite the occurrence of errors. It makes the copying process quicker and more efficient. For Example: even if an error occurs due to read-only files or protected files, the copying process doesn't stop.
- /y: If a message shows up saying that you want to over-write an already present file in the destination hard, then this parameter takes over. This parameter disposes of this message so that copy process remains smooth without ant halt.
It completes the list of required parameters. Let's jump straight into the action now.
Suppose you have a parent external hard drive named H and want to sync it with me, the destination hard drive. The command for the desired query would look as follows:
- Xcopy h: i: /e /d /c /y
The sync process would take its due time. The time is directly proportional to the size of the information present in the source file. The key is to avoid any interruption. Let the whole process complete, and after a while, your whole will be synced from the parent hard drive to the destination hard drive.
After doing it once, you never need to restart the entire operation again to transfer any data to the destination hard drive. The next time you sync these two hard drives, only the newly added or edited files will transfer from one drive to another.
It saves you from having multiple folders for the same information. It also quickens the data transfer process.
