WD my passport 2.5 for mac

I have a macbook air and an external hard drive for mac where I back up my data. None of the pc computers see the hard drive when I connect it to them even though I created a partition with an ExFAT format. How can this be solved?

Hello,

Windows is not able to recognize a partition formatted for Mac.

I recommend you create a Fat32 partition.
