Can't transfer files from MacBook to USB: error code -8062

Hey there! I recently purchased a new USB 3.0 flash drive of 128GB (San Disk Ultra Flair). My intention was to use it as a regular USB without utilizing the optional 'Secure Access' feature. So I decided to reset it using the 7-pass erase security option. The erase process took 11 hours and was successfully carried out. When I attempted to transfer my files using the usual 'command c + command v' method, the process initially started, but then I received an error message stating, 'The operation can't be completed because an unexpected error occurred (error code -8062).' I clicked 'ok,' but subsequent attempts to copy folders resulted in a stall, with the progress showing 'Zero bytes of __GB - Estimating time remaining...' without any further progress.

"The operation can't be completed because of an unexpected error occurred (error code -8062)" usually happens when copying large files from your Mac to an external storage device, such as a USB flash drive, hard drive, etc. It may result from permission issues or corrupted files.

To fix error code 8062 on Mac, try the following solutions.

① If the files you want to transfer from your Mac to the external drive need to be downloaded from the cloud, wait after they are fully downloaded before initiating the file transfer.

② Right-click your drive icon on the desktop, select "Get Info," then look at the "Sharing & Permissions" section. Click the yellow lock icon at the bottom-right of the popup window and enter your admin password to unlock it. Then, check if your account has "Read & Write" access to the drive. If not, modify the settings. After that, click the three-dot pop-up menu and select "Apply to enclosed items" to apply the permission to all files on the drive.

③ Take a look at the transferred files and resume the transfer from the next file. Or skip the next file that needs to be copied, as it may be the culprit causing the trouble.

④ Break your large file into smaller chunks and transfer one at a time.

⑤ If you are trying to copy Time Machine backup files to an external drive, use the Restore feature in Disk Utility instead. Note that this will erase data currently stored on your external drive.

⑥ Use a different way to transfer files from your Mac to an external drive.
