1. Exfat Format Software
2. Exfat Format Tool Mac

Hi Brandon,

Thank you for posting in Microsoft Community.

If you want to transfer files from a Mac to Windows PC and vice versa using an external portable hard drive then you have to have the external drive formatted in a file system both OS's can read.

The first thing you want to do is format your drive as exfat. Windows will only format a drive as exfat if windows recognizes it as a removable drive. Currently, you can’t boot to an exfat. So I redo the Raid 0 under Mac and format it as exFAT in MacOS. And now this exFAT works on both Mac and Windows 10. Very strange. Edit: I just figure out why in my case. When formatting exFAT in Windows 10 from Disk management. If formats the exFAT using Allocation unit size of 2048 kilobytes. In the 'File System' dropdown, choose exFAT instead of NTFS. Click Start and close this window when finished. From then on, that drive should work fantastically between Mac and Windows machines. Besides, you can format an external hard drive for Mac and Windows by converting HFS+ to FAT32 or exFAT without losing any data. Step 1: Backup Data in HFS+ Partition on Mac Just transfer all useful files out from the external hard drive to other devices on Mac.

I understand your concern and frustration you have been through. I will be glad to assist you.

Exfat Format Software

By default, Windows provides the option to format a USB flash drive with FAT or FAT32 file systems only, but not with NTFS (New Technology File System.)
The reason behind this is that there are some disadvantages of NTFS usage in this case. First of all, the speed of saving on the flash drive decreases (but the speed of reading data from the drive is the same), and you have to be more careful to always remove the USB flash drive safely.
However, you can still format the Flash Drive in the NTFS format. Follow these steps for the same.
1. Insert the USB flash drive into the USB port.
2. Press Windows Key + R, type devmgmt.msc in the Search textbox and press Enter.
3. Find Disk Drives and expand it.
4. Find the USB flash drive you want to format, and double-click it. It opens the Properties dialog box.
5. Click Policies tab.
6. By default, the Optimize for quick removal option selected, switch it to Optimize for performance and then pressOK.
7. Now open Computer. Right click on the USB Flash Drive and select Format. The Format dialog box now appears.
8. Select NTFS in the File System field.
9. Press Start and wait while the process will be completed.
10. Now your USB Flash Drive is formatted with NTFS format.
