I have a X99 board with same drive and Windows 10 as said no issues do not think it's an incompatibility with Windows 10, maybe a bad drive, missing, outdated, corrupt or conflicting drivers. Also try a different USB 3.0 Cable even though you sate you feel it is good and all other USB 3.0 ports. Hi, When I plug my usb3 My Passport drive into my Windows 10 laptop it shows up the CD (Unlocker element) which says the drive is unlocked. However the actual data drive part doesn’t show up in my computer.
I'm not sure. When I bought the drive several years ago I only owned that Macbook Pro so it's quite possible I did. What would I need to do to make it recognizable by both? Then it probably formatted as HFS or HFS+ then. There are some free utilities that let you read HFS from windows but not write.
OSX can read NTFS but not write. If you plan on regularly moving data back and forth paragon's NTFS on Mac or HFS on windows are highly regarded and fairly cheap. You only need one. There are a couple of file systems both can read but they don't handle 1Tb very gracefully.
Edit: exFAT would work pretty well for you actually. But only if you have windows 7/8 and OSX snow leopard or newer.
