What does an Error Code 1309 error message look like? If you encounter this error, this is the message you will read on your screen:
The operation can’t be completed because an unexpected error occurred (error code -1309)
It is noteworthy that this error message is quite old and it won’t go away because it is related to the external drive, not the operating system itself. The error happens when you are copying a rather large file.
How to Fix Error Code 1309 on macOS?
First, let’s cover the reasons why this error message is appearing in the first place. You should keep in mind that the file you’re trying to copy is corrupt. Another possible scenario is that the transferring process was interrupted because the drive was disconnected by accident.
The most notable reason, however, is the flash drive itself – because it has the FAT32 format. Did you know that flash drives usually support the NTFS (mainly used by Windows) and FAT32 format (used by both Windows and macoS)? FAT32, however, requires that the files cannot be larger than 4GB.
Since the error code is related to copying files larger or close to 4GB, you may need to reformat your external drive to another file format.
First, check the current format of your hard drive by opening Finder and locating the external drive.
The next step requires right-clicking and selecting Get info.
In case the hard drives turn out to be FAT 32, you will have to change it so that you can copy files larger than 4GB. The recommended format is Exfat because it is compatible with both Windows and macOS, making it more adaptable. How should you do this?
- Launch Disk Utility to erase and format the flash drive.
- Select the drive from the left bar.
- Click Erase at the top-right part of the screen.
- You are prompted to name the drive and select it format, so be careful to choose the correct format for your needs.
- Once the reformatting process is finished, eject the external drive, and wait a while before inserting it again.
Now, your files should copy without any trouble, meaning that you will no longer encounter the Error Code 1309 message on your Mac.
