Unable to copy some files to a local disk -- Macintosh
When files are unable to be copied to a disk, the cause is usually the formatting on the destination disk. Both Windows and Macintosh support a file format called "FAT32". While this is a good file system for compatibility between computers, it is unable to contain many file types. It's limitations are:
- Unstable at larger sizes, and very prone to corruption
- No security features, so anyone can access any file at any time
- Maximum file size of 4GB
- Can not contain files with \ / : * ? < > or |in the file name.
Because of this, most file transfer issues can be resolved by formatting the drive out of this format. To see if the drive is in FAT32, follow the procedure below for your OS
Locate the LaCie icon on the desktop or in a Finder menu on the left side. Click the icon once to highlight it. On the menu bar on the top of the screen, choose File, then Get Info. This menu will appear:
In the General menu, the 4th option down is Format. In this case, it identifies the disk as formatted in FAT32. Formatting the disk in Mac OS Extended will likely resolve the problem.
