You can use the Maxi PC suite to create a brand new SD Card. Autel recommended a SanDisk 32GB Ultra SDHC UHS-I Memory Card Class 10. Insert your Brand new SD card into an SD card slot on your computer and the PC Suite will create a brand new card for you. It works really well. I did this for my TS601. I have a Mac and this should work just as easily on a PC.
