[QUOTE="Rod, post: 1867781, member: 204485"] Well folks, I'm back up and running and yes it was a problem [I]related[/I] to the hard drive but hopefully not the HD itself. The problem was that I couldn't get anything to boot up to a stage where I could access Disk Utility. Neither the Recovery Partition or CCC and with Time Machine I just assumed it would erase the Target volume as part of the process but maybe not. It took a long time to find out that it too failed before completing restore and the MBP froze again. In retrospect I realise I should have used Disk Utility on the Time Machine backup to erase, format and map the HD first. Then I tried a Bootable Mojave Installer on a Thumb Drive. It booted successfully, so this time I opened DU and erased the HD, not the "Macintosh HD" volumes but the Apple Media Disk itself after first unmounting both Macintosh volumes (important). I was then able to instal Mojave. It seemed to be completely fine so I tried booting from the CCC backup and this time it booted without a hitch, restored my Catalina OS, all my data and the two volumes Macintosh HD and Macintosh HD_Data as APFS volumes. For a little while I was anticipating an expensive repair/replacement to my HD or at worst a replacement device. Not something I wanted to be forced into, especially at this time as I am hoping this device will last me till the generation of ARM computers arrive. Although a 2015 model it is in fact only 3 years old having been replaced by Apple twice. Once for a keyboard issue only weeks after purchase and again for screen delamination two years later.
