Formating USB drive connected to AirPort Extreme 802.11n (3rd Gen)
I have a 500GB USB drive connected to my AirPort Extreme 802.11n (3rd Gen) which will mount whenever I'm connected to the network. I'm looking to remove that and use it directly as a USB drive on my other machine. However, I am not able to find a way to reformat or erase the drive.
I've tried the following:
1. using Airport Utility - I can see the drive but I can't erase or format - click on the partition but no options provided
2. remove it from the Airport Extreme and connect it directly to the Mac via USB - but this only shows up the WD partition with some applications to download. I can't see it in Disk Utility as well.
Any suggestions?
thank you
