The challenge is that whether you're creating a hard disk partition or formatting for speed, the operating system can delete information, test disks, note bad sectors, and create internal address tables. In fact, annually formatting your hard drive can help you maintain peak performance for your computer. You decided to partition your hard drive to try to enhance performance speed and keep your files separated logically. Restoring from backup lets you retrieve that copy any time, regardless of whether your operating system overwrites the file. If you’ve created a backup of the file, you’re storing a duplicate version somewhere else so you can retrieve it if something happens to the original. However, if your operating system overwrites the information, the address and the information are gone forever. As long as that disk space hasn’t been overwritten, the file will be there. Recovery software simply helps the computer “remember” where certain files were stored on the disk. If they can find the right one again, their items will still be there. Following our drawer metaphor, it's not that the household items were destroyed – the owner just forgot which drawer they were in. When you delete a file, the computer usually deletes the digital address but not the information. As long as you remember which drawer they are in, it's easy to sort through them and find things. It's similar to putting household items in a drawer. It's easy to confuse the terms 'recover' and 'restore.' When your operating system saves a file, it saves the information and gives that information a digital address.
