While this naturally makes them superior to FAT32, it also makes them too inefficient for portable storage devices.ĭevices like SD cards or USB drives need a simple file system to write to and do not have a large overhead. A New Generation of File Formatsįile systems like the NTFS (New Technology File System) and HFS+ (Hierarchical File System), developed by Microsoft and Apple respectively for their own operating systems, are specialized to ensure the security and reliability of the data stored in the hard drive. These were critical issues for a hard drive meant to hold system files for an operating system. The format was too vulnerable to malicious code and did little to implement redundancies against data corruption. It is also widely supported by memory storage technology companies and third-party operating systems like OS X and Linux.With time, however, the FAT standard started showing its age. Microsoft introduced exFAT in 2006 it’s an optimized version of FAT, providing better performance advantages over FAT32. Now you’ll be able to save and copy files to your thumb drive on both Windows and OS X. In the Format list box, select ExFAT, enter a Volume Label if you want, then click Erase. Select your thumb drive in the Disk Utility window, then click the Erase tab. Launch Disk Utility press Command+Space then type: disk utility. If you only use a Mac computer, you can format your thumb drive to work on Windows systems.Ĭonnect the thumb drive to your Mac. In the File System list box, choose exFAT, type in a Volume Label if you want, and then click Start.Ĭlick OK to the format warning and wait until the process is complete.

Right-click your flash drive and then select Format. Prepare a Thumb Drive for Both Windows and OS X or macOS Before you start, though, make sure your thumb drive is formatted so it can work on both Windows and macOS. If you’re working in a mixed environment, where you might need to work on files between both systems, a handy solution is to use a thumb drive. This makes it difficult to move data between the two unless you have them networked together. MacOS uses the HFS+ file system, while Windows uses the NTFS file system that shares little in common.
