Sorry this is a complex issue - I so appreciate any advice or tips you have. What would you suggest to recover the data from Macintosh HD partition?

When I started up the Mac in Recovery Mode Disk Utility, the MacHD was replaced by a greyed out disk called 'Untitled'. Some might equal Disk Utility to Disk Management in Windows system. You can still open or copy files on the disk, but you canвЂ™t save changes to files on the disk.

Okay first of all, as usual my external drive (used for Time Machine backup) was unproperly ejected as I wake the computer up. If the drive has been mounted, there will be an option to unmount the device. so obviously the physical spinning HD is OK for now. Click on the volume for a menu to appear. However, my Windows Bootcamp partition was still there and is operating fine. I then tried plugging the Macbook into another computer via Target Disk Mode, and the MacHD was still not showing up.

With Recovery I tried to repair the disk, but I got. As I was about to copy the files over, the Macbook's Macintosh HD disappeared from Finder on the other Mac. The volume Macintosh HD could not be verified completely. The best solution is to mount the external hard drive again using Disk Utility, then scan and restore all data from the external hard drive by using professional Mac hard drive recovery software.
