Sometimes we need to replace a new computer. If the old computer is not placed or needs to be handed over to others, many private information in the computer will be completely deleted. Some netizens don't know how to delete it completely and will only delete folders in the computer. This is not complete. What are the specific methods?
Completely delete method 1: delete first and then store.
Before computers are eliminated, delete personal privacy files first, and then empty the recycle bin. Copy some unimportant files in until the whole hard disk is full and can no longer be copied in. In this way, the newly copied files will completely overwrite the deleted files.
Method 2: low level formatting.
For people with certain computer knowledge, you can try low-level formatting to completely delete the data in the computer, but it will cause great damage to the hard disk.
Method 3: magnet adsorption hard disk.
For example, there is no possibility that the magnet can completely restore the data on the hard disk after a few minutes. If the magnet is turned on, it is almost impossible to completely restore the data on the hard disk.
Method 4: completely damage the internal components of the hard disk.
There is also a faster way to clean the data, that is, directly disassemble the hard disk and completely damage the disk similar to the optical disk in the hard disk, so as to completely clean the data in the hard disk.
The digital camera only borrows the machine, not the memory card. In addition to the computer, we should also be careful to prevent the privacy of digital products such as mobile phones and digital cameras.
Now many mobile phones have memory cards. Users had better not take photos involving important privacy or store important files with their mobile phones. If you do not intend to use the mobile phone memory card, you'd better wipe the memory card with a magnet, and the information will become invalid.
For digital cameras and digital video cameras, it is best not to lend them to others. Digital camera and digital video camera even if you delete the photos, you can easily restore the photos with professional software. If you can't refuse to borrow the digital camera or video camera, you'd better borrow only the machine instead of the memory card.
