Why does my usb have less space than it says?

Why does USB have less space than it says? Please ensure you're selecting the correct drive, and understand that hardware issues or firmware restrictions may not be fixable with this method. If the drive continues to show less space after these steps, consider testing the drive on another computer or contacting the manufacturer for support.

There are some disadvantages and risks associated with this process, especially if your USB have less space than it says:

• The clean command erases all data, partitions, and file systems on the drive. If you haven't backed up important files, they will be permanently lost.
• Sometimes, the drive may have hidden or unallocated partitions that are not fully removed by clean, especially if the drive has hardware issues or firmware restrictions. This can cause the drive to still report less space.
• If the drive has physical problems, such as bad sectors or hardware faults, reformatting won't fix these issues and could potentially worsen them.
• If you select the wrong disk (e.g., a different drive), you could erase important data from other drives, leading to data loss.
• If the discrepancy in space is due to firmware or controller issues, Diskpart won't fix it. The drive might need replacement or specialized repair.
• Some manufacturers may void the warranty if you perform low-level formatting or modifications beyond standard use.
