either your hard drive is going bad,
or your doing a full format witch writes all 0s to the hard disk if you do a quick format it just deletes the registry and the information is over written. It is always better to do a quick long format
Hard disk formatting means preparing new space for data storage. This is by creating tracks and sectors in the disk.
Formatting prepares a floppy disk to store data
it does not divide a disk by necessity. you can chose, when formatting, to divide the disk into partitions, but this is not necessary. default is that you have no partitions (which is technically the same as 1 partition).
This is called "Disk Formatting" "Formatting"
Universal Disk Formatting
It wipes out data on the hard drive disk.
A low-level format is the process that marks the location of tracks and sectors on a disk. A disk cannot be partitioned or formatted until a low-level format is completed.
That would be called low-level formatting.
When you delete a file on a filesystem all that is really done is that the disk "forgets" where the data is stored. It remains on the disk until it is overwritten. Formatting is a more technical term than most people understand. A common misconception is that formatting is simply deleting all data on a disc. In fact formatting is more of a "reconfiguration" of the disk. Formatting is the process where a system of data storage is applied to the disk. As a bi-product of this the system which remembered the layout of the origonal data is replaced and therefore the data inaccessible. It is however a common feature of most formatting tools to physically destroy the data as part of the formatting process.

No, backup is most certainly not that. Formatting is the process fo dividing the disk into tracks and Sectors.
