I just found this out, and was so excited, I wanted to share it with everyone. If you have an apple/mac, and you want to transfer files between your USB-flash drive and your computer with top speeds, here’s how you do it (backup your files before doing this – it will erase everything on there):
1. Plug in your USB-flash.
2. Go to ‘Disk Utilities’ (in the Applications/Utilities folder)
3. Select the orange icon for your disk on the left.
4. Click on the ‘Partition’ tab (this may take a while to load).
5. The format will be ‘MS-DOS File System (FAT-16)’. Change it to Mac OS Extended.
6. Partition!

Note that if you use the flash drive with both windows and macs, you won’t be able to do it exactly like this. But, you can partition the drive into two parts, and let one part be Mac OS Extended, and the other part left as MS-DOS…
