Yes, you can safely reuse your flash drive after wiping it clean with MultiDrive and quick-formatting it in Windows and other operating systems.
Flash memory has a limited number of write cycles. However, it's not likely that wiping a USB drive a few times will cause any noticeable damage or significantly reduce its lifespan.
It's better to know for sure that your sensitive data is gone for good, even if it does a little bit of damage to the drive.
Think of your USB drive as a library.
Deleting a file is like removing a card from the catalog. The book (your data) is still on the shelf, and another person can still find it. The space is simply marked as available for a new book.
Formatting is like emptying the entire library and replacing the card catalog system. But it's tricky:
- Quick format just removes the catalog, making the books invisible but still physically present until new books are added.
- Full format goes a step further by checking the shelves for damage and sometimes writing zeros over the existing books, making them much harder to find.
Secure erasing is like shredding every single page of every book in the library. This process overwrites the entire drive with random data or some binary value making the original information practically impossible to recover.
