How can I restore USB drive back to full capacity in Windows 11/10?

Restoring USB drive to full capacity in Windows 11 by deleting partitions and formatting it is generally safe — as long as you’re careful and make sure you’re working on the right drive. 

Here’s the deal:  

• When you restoring USB drive to full capacity in Windows 11. If you accidentally pick the wrong drive in Disk Management or Diskpart, you could wipe out your main hard drive or another important drive. That’s a big no-no.
• Always double-check the drive size and label before hitting delete or clean.
• Make sure you’ve backed up any important data first — because this process erases everything on the USB.

In my experience:  

• It’s pretty straightforward, and most of the time, it works without issues.
• Sometimes, if the drive has hardware problems or bad sectors, formatting might not fix everything, and the drive might still be unreliable.
• If your drive was previously partitioned or had a corrupted filesystem, this method is actually a good way to fix it.
