FAT32, on the other hand, is a file system that can be read and written to by both Mac and PC, making it the perfect choice for sharing files between the two.
Benefits of FAT32
There are several benefits to formatting your external hard drive to FAT32. For one, it’s universally compatible, meaning you can use it to share files between Mac and PC without worrying about compatibility issues. Additionally, FAT32 is a relatively simple file system, which makes it less prone to errors and corruption. This means you can rest assured that your files will be safe and secure when stored on a FAT32-formatted drive.
Limitations of FAT32
While FAT32 has its benefits, it also has some limitations. For one, it has a maximum file size limit of 4GB, which can be a problem if you need to store larger files. Additionally, FAT32 doesn’t support file permissions or access control, which can be a security concern if you’re storing sensitive files. However, for most users, these limitations won’t be a major issue, and the benefits of FAT32 will outweigh the drawbacks.
Formatting Your External Hard Drive to FAT32 on a Mac
