Fix 2. Rename the Files and Copy to the USB Drive Again

Renaming files to fix the copies of the files to a USB drive disappear issue may sound strange, but it works.

So, rename these files to try to copy them correctly.

Fix 3. Reformat the USB Drive and Try Again

One of the main reasons why files disappear after being copied to a USB flash drive is because of file system mismatches. There is no formatting problem with the files that disappeared, and it is more likely that your USB file system is incompatible with macOS Sonoma/Ventura/Monetery or older macOS versions, causing the files to be displayed and read abnormally.

In this case, it is recommended that you backup your USB flash drive first. You can use the EaseUS data recovery software, which provides a quick backup function.

Here are steps to back up your USB flash drive (also works to back up other external hard drives, SD cards, etc):

Step 1. Click "Disk Backup" > "Create Backup" > "Next" in EaseUS Data Recovery Wizard for Mac's main interface. You can create a drive backup image file in case the data is overwritten.

Step 2. Select an internal volume to back up, and click "Create Backup". If you want to create backups and recover data from an external hard drive, USB flash drive, or SD card, remember to connect the storage device to your Mac in advance.

Step 3. Choose a place to save your backup files, and change the name of your backup file, then click "Save". It is not wise to save backups in the same storage device that you want to recover data from.

After backing up your USB flash drive, you can reformat it using Disk Utility on your Mac. Check out the following steps to format the USB drive to FAT32:

Step 1. Connect the USB flash drive to your Mac. Open "Disk Utility" from "Applications > Utilities" on your Mac.

Step 2. Find the USB flash drive in the left devices list, select it, and click "Erase" at the top menu.
