Plug the SanDisk USB drive into an available USB port on your computer.

Enter a new volume label (name) for the USB drive in the “Volume label” field. This is optional but recommended for easy identification.
7. Perform a Quick Format
Check the “Quick Format” box to perform a faster format process that only erases the file system without scanning for bad sectors.

Click the “Start” button to initiate the formatting process.

Advanced Formatting Options
1. Full Format
Instead of a Quick Format, you can perform a Full Format to scan for bad sectors and repair them. This process is slower but more thorough.

The allocation unit size determines the size of clusters on the drive. Smaller allocation units can improve performance for small files, while larger allocation units are more efficient for large files.
3. Drive Letter
You can change the drive letter assigned to the USB drive in Disk Management or Disk Utility.
4. GPT vs. MBR Partition Table
GPT (GUID Partition Table) is the newer partition table format that supports larger drive capacities. MBR (Master Boot Record) is the older format, which is limited to drives up to 2 TB.
