Macbook Pro Retina and ultra plus as external usb disk


I tried to connect  an ultraplus 256 as an external usb disk in my MacBook Pro Retina (15" end 2014). The disk is not recognize (does not appears in the the macbook disk utilities )

Its works well / recognize using a windows PC

the disk is new and has been formated on a PC in FAT32

Any idea ?



in that case you can try to format the drive on NTFS or ExFat with the windows computer and then see if the drive is still not detected by the mac computer. 

Have u fixed it up…!
