After using SSD on one of my PC and missing the blazingly fast speeds of it on my Apple Mac computer, I finally decided to get the iMac upgraded to SSD. To get data migrated from the old iMac Disk to my new Samsung EVO 850 SSD, I connected both to my other system running Windows 10. I installed and tried 3 popular data migration utilities on the Windows 10 PC which claimed to get the HDD to SSD migration job done, but all of them failed to recognise and clone the HFS+ (Mac OS X Partition) from the Bootcamped dual-boot configured iMac HDD.

Luckily, my memory served me on time and I went ahead using excellent, free "HDD Raw Copy Tool" utility for Windows to get the old HDD disk cloned as an exact one-to-one copy without any partition issue. We have used the same tool earlier to make compressed backup copies of Raspberry Pi SD-Card.

EASEUS Disk Copy is one of the best disk cloning utility out there, the free platform independent bootable CD allows sector-by-sector disk/partition copying, via an easy to use wizard driven friendly graphical user interface, EASEUS Disk Copy can be used to copy, clone, or upgrade your original small hard drive to a new larger drive.
