When you connect a flash drive, Windows asks the Memory Controller, "How big are you?" The controller checks the and the File Allocation Table (FAT/NTFS) to report the size.

Tech consumers frequently seek affordable ways to expand device storage. This search often leads to software utilities claiming to increase capacity. One widely discussed utility is the . Sdata Tool 64gb
One customer review from an online marketplace described the physical "Sdata 64GB" USB drive bluntly: "Very bad item, they sold it as 64GB, but it is 32GB, Very slow... It is garbage". This suggests that even if a physical product exists, it is likely a low-quality, fake-capacity drive that uses the software's misleading name to scam buyers. You should approach any hardware bearing the "Sdata" brand with extreme caution.
If you use Sdata Tool on an 8GB drive to make it look like a 64GB drive, the first 8GB of data you copy over will save normally. However, once you cross the 8GB mark, the drive runs out of physical silicon. Because the firmware has been hacked, the controller does not throw an "Disk Full" error. Instead, it loops back to the beginning of the drive and begins overwriting your old data. 2. Immediate Data Corruption When you connect a flash drive, Windows asks
However, there is no widely known academic paper specifically titled "Sdata Tool 64gb" in major databases (Google Scholar, IEEE, ACM, etc.). Here are the most likely possibilities:
The software is designed for Windows and works on any removable drive, including microSD cards used via a card reader. However, the same limitations apply. It does not create real usable space, and using it on a card with your phone's data is almost guaranteed to result in the corruption of apps, photos, and operating system files. This search often leads to software utilities claiming
If you truly need 64GB of portable storage, your best bet is to purchase a legitimate USB flash drive from a reputable brand. A "64GB" drive, when properly formatted, provides approximately 59.6GB of usable space due to how file systems and decimal vs. binary measurements work. For everyday file transfers and backups, a standard USB 3.0 or USB 3.2 drive with read/write speeds of 100-150 MB/s is usually sufficient.
The tool often "tricks" your computer into seeing a larger capacity (e.g., 64GB showing as 128GB) without actually adding physical memory.
If you have used this tool and want to verify the real capacity of your drive, use professional diagnostic tools that write and read back data to test every sector: H2testw (Windows): The gold standard for detecting fake or "ghost" storage. FakeFlashTest:
