Question: Time machine copying to new drive
I am wanting to replace my TM b/u drive from 2TB to 4TB. I copied backup files using finder to 4TB drive but it is still saying "preparing to copy" 48 hours later and 18 MILLION items and still going. My backup goes back to June 2016.
Should I disbandon this and start again using another way or persevere until it is all prepared to copy and then will probably take days to actually copy?
