Got an error while copying a video file onto external disk

Asked By 0 points N/A Posted on -


I was trying to copy a video file that I edited in my Mac onto an external hard disk when I got this error message (see below).


The operation can’t be completed because an unexpected error occurred (error code 0)


The error message didn’t give any helpful hints on how to resolve the error. 

Can you please help me? I didn’t know what to do next.  I tried copying it several times but still got the same error.

Hello Maruta,

The error you are experiencing while attempting to copy your file from Mac to  the external hard drive could be due to the format of the hard drive that you are using. In case you are using a FAT 32 format for the hard drive, then you have to know that the file size that you can copy is limited to about 4 GB.

And therefore I will suggest that you do a reformatting to your hard drive to a Mac OS extended format which is also called HFS+ in case you want to use it with the MAC, for FAT 32 format works well with windows operating system. To change the format you will need to use the Disk Utility.

Hope this helps.

Try checking the file system used on the external hard drive. If the drive is to be used with a Mac computer, it must be formatted with either FAT32 or exFAT file system. Also, if you need to share one hard drive for both Windows and Mac, you need to use the correct file system.

With Mac, whatever hard drive works on a normal PC should also work with a Macintosh computer. The only problem you may encounter is with the file system because Microsoft Windows and OS X use different file systems by default. In Microsoft Windows beginning in Windows XP, the default file system is NTFS.

In OS X, it can access hard drives formatted in NTFS but it’ll only work in read-only state by default. If you need a hard drive that can be accessed by both Microsoft Windows and OS X, you need to format the hard drive with either FAT32 or exFAT file system. Microsoft Windows supports three file systems: FAT32, NTFS, and exFAT.

Of the three, FAT32 is the oldest file system available to Windows. With FAT32, you can’t have a file larger than 4 GB.
