SanDisk 64GB Flash Drive Only Showing 32GB, How to Fix
I have a SanDisk Cruzer 64GB USB, which I created as a Recovery Disk a few weeks ago. But then I erased everything on it to store files for personal use. However, when I go to File Explorer, it shows that the 64GB USB only has 32GB of space.

There could be several reasons why a SanDisk 64GB flash drive is only showing 32GB of storage capacity:
- The USB drive is formatted as FAT32, with a limited maximum partition of 32GB.
- Invalid partition on your USB drive.
- It has a Windows installation/recovery partition.
To recover your SanDisk USB drive to its correct capacity, you can format it from FAT32 to NTFS. EaseUS Partition Master Free is your go-to solution. It has an advanced feature helps you format a disk from FAT32 to NTFS without losing data.
This is how to do it:
Step 1: Insert your USB drive and start EaseUS Partition Master.
Step 2: Right-click on the USB drive's partition and select "Advanced" > "FAT to NTFS."
Step 3: Verify the message and initiate the procedure.
Then, you can use Disk Management to make it display the entire storage capacity. Follow the instructions below:
Step 1: Hit the "Windows + X" keys, locate and launch Disk Management.
Step 2: Select "Extend Volume" with a right-click on the intended partition.
Step 3: Follow the on-screen instructions and finish the procedure.
Then, the USB drive will show 64GB on your computer, and you are allowed to make full use of it.
