USB not showing its full capacity issue might arise due to corrupt files or improper formatting, etc. When this issue occurs, it can be annoying and restrictive, especially if you want the entire storage space to save important programs or information.
Why does the USB Drive not show Full Capacity?
1. Damaged Drive: If your USB drive is physically damaged, its storage capacity can change. The USB's capacity display may show a higher or lower capacity.
2. Malware Infection: Virus or Malware infection might also be a reason that changes the actual storage capacity of your USB drive and makes your USB inaccessible. Hence you need to remove the viruses from the USB to make it reusable again.
3. Faulty Formatting Issues: There are chances that your drive can become mostly unusable if you format it wrongly or configure it incorrectly.
4. Creating Multiple Partitions: If you have partitioned a USB drive into numerous sections, this makes Windows unable to recognize more than one partition, which prevents your USB drive from exhibiting its full storage capacity.
5. Hidden Partitions or Unallocated Spaces on PC: At times, there might be Unallocated spaces or hidden partitions existing on your USB drive that are invisible to the PC. Thereby not showing the actual capacity of your USB.
