Cloning HDD from Mid 2012 Macbook Pro

I have been trying to clone my HDD in a mid-2012 Macbook pro with plans to upgrade to SSD. I have tried a myriad of things to accomplish this task, but I have had lots of issues erasing the drive in disk utility. I eventually resorted to erasing the drive in terminal. I have tried cloning the drive in disk utility, Superduper, and seem to be getting closer to an understanding with a trial of Carbon Copy Cloner.


What appears to be happening is some sort of conflict with the destination drive. Admittedly, I haven't done much by way of cleaning up my temporary files, etc on the current booting drive. Because I have a simple Sata3 to USB 3 cable connecting them, I am unsure if my connection would be causing this.

I have scanned with DFA and tried multiple times, and getting pretty frustrated. Before the most recent error in CCC, I was informed by the software that there was a conflict with the destination drive in a folder marked "Resources" which I can only assume is a partitioned section that WD places on their drives, and CCC asked what I wanted to do. I deleted it and erased the drive and formatted APFS in terminal. This too failed to clone in CCC.

Any suggestions?


Computer: Macbook Pro Non-Retina Mid 2012, I5 processor, 16 Gb ram, 320Gb HDD, Os 10.15 Catalina.

SSD Drive: WD Blue SA510 1TB


MacBook Pro 13″, macOS 10.15

My issue was solved after I cleaned up the HDD. I had a lot of old files and other clutter on that drive, I eventually formatted/erased in terminal, then I erased and formatted it in disk utility. I ran first aid on all drives and volumes etc. I cloned it in Carbon Copy Cloner (used the trial) and was successful. I can say that the ap I used to clean the drive stopped clearing data at 500 Mb before asking me to purchase the license to finish. I cleared my downloads which seemed to help a lot. I am only spelling this out for others, but make sure you clean up both and match the format, this case APFS. Carbon Copy Cloner won over Disk Utility and Superduper which popped up in search. Carbon Copy Cloner gives you more information on what errors prevented the cloning to happen. I replaced my battery and moved to SSD. Thank you for responding!
