Takes time. I erased my La Cie PORSCHE DESIGN 500GB external hard drive and started a whole new Time Machine back up. I only have 190GB to back up (2013 iMac) but so far it has taken 45 hours and 35 minutes and backed up 167GB. Fingers crossed that all will be well. I estimate the back up will have taken about 52 hours.
iMac 21.5″, macOS 10.15
Have you tested the health of the External Hard Disk using DriveDX? If any errors appear replace the External Hard Disk.
What system are you using and how is the LaCie drive formatted?
Hi.
Many thanks for the responses. Back up has finished and seems to have been successful. Took somewhere between 50 and 57 hours.( I was asleep). So far so good. OS is Catalina 10.15.7 and drive is formatted OS Extended Journaled.
