However: storing the photographs on one disk only is a desaster waiting to happen. Should you ever wish to migrate from MacOS to another OS, replacing the 2GB disk and formating it to the native format of the new OS would not break the bank. Other advantages of the native file systems over the FAT ones are not so important when the usage pattern consists of storing each directory and file once and retrieving many times, without changing many files or directories once written.

So, in the rare case of a system crashing or a disk becoming separated from the computer or losing power while any writing is going on, the chances are much better that the system may recover the data and the free space on the disk. Secondly and even more important, the native file systems of all major operating systems keep journals of all operations performed on the disk.

For one, the FAT file systems do not support all properties and attributes of a file system designed for permanent storage. I do not recommend this for the permanent storage of my work. I would always format an external disk to FAT32, as Mac OS has no problems reading and writing in that format, whereas a Mac formatted disk cannot be read by a Windows computer, which can be very unpractical.
