I finally upgraded the OS SSD in my gaming PC. Went from a 250GB to a 1TB. #Clonezilla and #gParted made it so simple. It took all of 20 minutes or so!
Using #clonezilla to clone one 8TB HDD to another with a btrfs file system. It has been sitting at "Calculating bitmap... Please wait..." for a long time.
I just want what I have: I can run Clonezilla, have an exact replica of my HD .. No Apple, no Microsoft, no nothing .... Just please: I can swap out the HD with another HD any time I want.
