[QUOTE="Slydude, post: 1834471, member: 131855"] I'm not sure how a CCC clone behaves when one tries to boot using the Option key method. That's what I was trying to correct. As for the loss of data and loss of my Mojave partition, that was [B]not[/B] the fault of CCC. My thought was to split my Mojave drive into two partitions and place a clean Catalina installation on the blank area I created on that drive. In essence, the drive would have had a Mojave clone and Catalina clone on the same drive. I've done that many times in other OS versions with no issues. I created the necessary space using Disk Utility and must have gotten a bit careless and selected the wrong drive. Net result, -- Mojave clone erased entirely. When I tried the Catalina install I had made on that external drive it did not boot when the option key was pressed so I decided to try again in case I had skipped a step. This time I accidentally selected a different drive with quite a bit of data and [B]erased that drive as well[/B]. Let's just say I had a very bad day that day. [B]These losses were not due to errors/bugs in Disk Utility or Carbon Copy Cloner[/B]. The mistakes were mine and mine alone. I was doing several other tasks during this time and not paying enough attention. That's probably going to cost me a hat or two. [/QUOTE]
