How to Clone Hard Drive

Windows already comes with a great tool for disc cloning, Robocopy.

To use it, start the command prompt.
Here is an example to clone disc M to N:
cmd> robocopy.exe /r:2 /w:1 /dcopy:t /mir /v /log:mn.txt m: n:

Explanation:
/R:n : Number of Retries on failed copies - default is 1 million.
/W:n : Wait time between retries - default is 30 seconds.
/DCOPY:T : Copy Directory Timestamps.
/E : Copy Subfolders, including Empty Subfolders.
/V : Produce Verbose output log, showing skipped files.
/MIR is an option to ROBOCOPY where you mirror a directory tree with all the subfolders including the empty directories and you purge files and folders on the destination server that no longer exists in source. 

It will also copy the exact dates of files and directories,but you can adjust it if you want.

You can also make a shortcut to this command on your desktop. Then you can start your backup whenever you want to.

What are the benefits of Hard Disk Partitions?

Disk partitioning is the act of dividing a hard disk drive into multiple logical storage units referred to as partitions, to treat one physical disk drive as if it were multiple disks. Partitions are also termed "slices" for operating systems based on BSD and Solaris. A partition editor software program can be used to create, resize, delete, and manipulate these partitions on the hard disk.

Benefits of multiple partitions
Creating more than one partition has the following advantages:
Separation of the operating system (OS) and program files from user files. This allows image backups (or clones) to be made of only the operating system and installed software.
Having an area for operating system virtual memory swapping/paging.
Keeping frequently used programs and data near each other.
Having cache and log files separate from other files. These can change size dynamically and rapidly, potentially making a file system full.
Use of multi-boot setups, which allow users to have more than one operating system on a single computer. For example, one could install Linux, Mac OS X, Microsoft Windows or others on different partitions of the same hard disk and have a choice of booting into any compatible operating system at power-up.
Protecting or isolating files, to make it easier to recover a corrupted file system or operating system installation. If one partition is corrupted, none of the other file systems are affected, and the drive's data may still be salvageable. Having a separate partition for read-only data also reduces the chances of the file system on this partition becoming corrupted.
Raising overall computer performance on systems where smaller file systems are more efficient. For instance, large hard drives with only one NTFS file system typically have a very large sequentially accessed Master File Table (MFT) and it generally takes more time to read this MFT than the smaller MFTs of smaller partitions.
"Short Stroking", which aims to minimize performance-eating head repositioning delays by reducing the number of tracks used per hard drive.[1] The basic idea is that you make one partition approx. 20-25% of the total size of the drive. This partition is expected to: occupy the outer tracks of the hard drive, and offer more than double the throughput — less than half the access time. If you limit capacity with short stroking, the minimum throughput stays much closer to the maximum.

It will help you more if you own a disk partition management software.

How do I deleted a disk partition that is write protected?

What OS ARE YOU USING??? IF IT'S WINDOWS 95,98, OR MILLENIUM, YOU WILL HAVE TO USE FDISK.EXE at the command prompt. IF IT'S NT4.0,2000, XP, VISTA OR "7", YOU CAN USE DISKPART.EXE FROM THE C:\WINDOWS SYSTEM32\ directory at the command prompt instead, or better yet, right click on the start button itself, choose manage my computer, and use the disk administrator tool under the storage tab to list and change partitions at will. right clicking on any of the drives/partitions in the disk administrator tool will bring up the menu of what you can do to each partition.
