When you delete a file in windows, the OS merely deletes the handle to the file so that users will not be able to retrieve the file directly.However, the file is still retained in the hard drive and it can be retrieved using good data recovery software. It must be noted that even formatting a disk does not delete data or files completely.

When using the FORMAT command in Windows, you may receive the following message.

Important: Formatting a disk removes all information from the disk.

In reality, the FORMAT utility actually creates new FAT and ROOT tables, leaving all other existing data on the disk untouched! Moreover, an image of the replaced FAT and ROOT tables is also backed up, so that the UNFORMAT command can be used to restore them. In addition, even the FDISK utility cleans the Partition Table (located in the drive’s first sector) and does not do anything else.

Thus, data can be retrieved from your hard drive or disk using sophisticated data recovery software. Hence, to ensure that data is completely wiped or erased from the hard drive, it is recommended to use good hard drive erase utilities like Active Kill Disk.
