My client plugged a WIN-formatted Hitachi external into his new MacBook Air (OS10.11) and of course it wouldn't mount. But now it won't mount to his old laptop, either. Is there any way to force it to mount, or at least recover files from it? Seems like I have seen this solution somewhere once, but can't remember it--or do I need to go straight to a data recovery service? Oh yes, it's not visible in DiskUtility
