Format issue on New HD

Unit connected ok by wireless, However on first time connection to PC by USB cable , greeted by following message, ‘’ You need to format the disk in drive ‘‘G’’ before you can use it’’ is this normal ,

Hi,

It could be a power issue.

Is that a laptop or desktop? if is a desktop computer, make sure to test the unit using the USB ports on the back of the unit.

Thanks for your reply. I have tried this on 2 laptops and 2 pcs so I do not think its a issue on the pc side. Is it safe to go ahead and format
