Time Machine Takes Ages to Perform First Backup
Following a previous problem with my 2TB Western Digital External Drive, I re-formatted the drive and wish to use it as my Time Machine for my Apple iMac, running High Sierra (Version 10.13.6).
I am trying to perform my first Time Machine Backup of 437.66GB, but although my Finder programme confirms that my Time Machine drive is doing so, it has not moved off the first 58MB for over three hours now and reports that it is "calculating time remaining"!
I understand that the first Time Machine Backup should take a long time, but how long is a 'long time' and what timescale should I expect this first backup to take?
Any help would be gratefully received
