Formatting a hard disk
When you format your hard disk, the operating system erases all addresses, pointers and files related information on the disk. Scans the hard disk drive to ensure that all the sectors are consistent and creates address tables to locate information that will be stored later on the disk. Every hard disk should be formatted before using it for the first time or after reinstalling the operating system. Format means preparing the hard disk or any storage medium such as memory card, USB drive etc. for use, including setting up a file system.
Therefore, you can say that the data is still available on the drive even after formatting, re-formatting, re-partitioning or re-installing operating system on hard disk drives. So when you delete or format a hard drive without making any backup the data do not get lost / deleted completely from the drive. Instead, the pointers to the files are deleted from the file directory table. The data will remain in the hard drive until it gets overwritten by new data / files.
