Ixpand 3.0 reset after accidentally formatting it in Mac

Dear all,
I accidentally formatted the ixpand 3.0 when making a bootable usb stick for my macbook. Now sandisk software doesnt recognize it anymore, does anyone know how i can get it back to factory settings?

Thanks in advance

If you are formatting with a Mac you will need to reformat the drive using MBR (Master Boot Record) for the partition scheme and use FAT32 (MS-DOS file type) or exFAT for the file system.

If you have a windows machine just format with the default settings using FAT32 or exFAT for the file system.
