The easiest way to clear hard drive completely is to produce its formatting. This can be done directly from within Windows by going to My computer and selecting the drive right click. In the drop-down list, specify the command Formatting. By choosing the sizes of the clusters and the speed and depth of formatting, click OK. After some time, the operation will be completed, and the disk is cleared. However, if the hard diskfrom which you want to remove information, system, and, if necessary, to completely clean hard disk unrecoverable data, the described variant is not suitable.
To work with diskAMI on a deeper level, you will need program managers sections. For Example, Partition Logic, Partition Manager, BootIt Next Generation, Acronis Disk Director.

Booting from it (after putting in the BIOS to primary boot from CD-ROM), you will be able to format the system and any other mounted hard drive. Thus the data from them will be deleted.
If you need to completely clear a hard drive without recovery information, start Acronis Disk Director. In the window where you can see a list of installed drives and partitions on them, select the desired disk , right-click. In the drop-down menu, select the item "Delete data". In the window that appears, enter the settings for the delete operation, and click OK.
