Hey Nick! 👋
No worries at all — you're not alone in this, and it's great you're asking for help. Let me walk you through a simple, step-by-step fix using the tool mentioned on that AOMEI Partition Assistant guide — it really does the trick for many people with this exact issue!
✅ Here’s how to restore your USB back to full 256GB on Windows 11:
Download & Install AOMEI Partition Assistant
Go to the link you shared: AOMEI Partition Assistant and click the Download Freeware button.
Insert your USB stick (Sandisk Ultra 256GB)
Make sure it's properly connected. Wait for the system to detect it.
Launch AOMEI Partition Assistant
Once open, you'll see all your connected drives listed.
Locate your USB Drive
Look for the one that says something like Disk X – Removable and shows only 3.1GB or so.
Right-click on your USB Drive’s Partition
Then select Delete Partition → confirm the deletion.
Now, right-click on the unallocated space (it should now show full unallocated capacity)
Choose Create Partition → format it as FAT32 or exFAT (recommended for larger drives) → click OK.
Click “Apply” in the top left corner
Then hit Proceed to execute the pending operations.
Wait a bit... and boom! 🎉
Your USB should now be restored to its full 256GB capacity!
