    This is my first time on the forum so greetings to you all! I have a late 2012 iMac who's 3TB HDD failed. I decided I'd rather have the speed than extra storage so I'm replacing it with a 1TB SSD. I will now have 128G flash + 1TB SSD. Seeing as how a fusion drive no longer makes sense, what...

    I'm trying to access my MacBook Pro hard drive on my PC. It's not being recognized by MacDrive or HFSExplorer because it's encrypted and uses CoreStorage. Are there any possibilities to access this drive on my PC?
