I have a 350 GB hard drive that I use as a Time Machine backup, and have for the past few years. Recently, I upgraded my computer to a 2013 MBP from an aging 2006 MB, and with the upgrade, came an increase of hard drive space, from the 80 GB to 500 GB. Which meant eventually, my data wasn’t going to support the new space. So I purchased a 1 TB hard drive to use as a new Time Machine drive. I decided to copy over the data of the current Time Machine to the new 1 TB external (which took an entire day). During the transfer, I got a few messages that said “this file could not be copied”, and lost about 3 GB of data compared to the old hard drive. The current Time Machine hard drive is in tact. Now I’m at a crossroads. Did I do something wrong with the Time Machine copying data and try again with another method, or scrap it and either inherit the backup on the older hard drive or start a new backup on the new hard drive? Thanks for the answers in advance.
