My 2010 Mini is long in tooth and probably going to die in the new future. Ethernet quit working months ago. Wifi still work. Anyways, I clone (forgot the program) to an external drive so I can boot from it if the internal drive would crash. IF I get a new mini, will the new mini be able to read the data on my external drive? My main concern are the large photo files. My mini reboots when it gets warm so think the fan quit working and not sure if it would stay on transffering the 400 GB photo file. Appreciate any help.
