But my problem is that I have no space whatsoever on my MacBook Air (my flash storage is limited to 128 GB of space) to create a backup copy. I read the forums and see that everybody is recommending making a backup copy and giving a new format to the external hard drive. When you click on it, you are again subjected to extreme torture in the form of another insane amount of loading time until the folders and icons finally show up, if they do at all. After the hour has passed, a golden-coloured external hard drive icon shows up.

Of course, I checked the format and it is still exFAT indeed. However, every time I try to connect that same external hard drive to my sleek, modern MacBook Air, the transmission seems to stall from the very beginning and can take almost 60 minutes to load. Several seconds pass (no more than 10) and I am ready to browse the contents of the drive at leisure. Whenever I connect the external hard drive to my tiny, cyan-colored HP Stream, the PC manages to read the device instantly, even if the computer resembles a child's toy and has a mere 2 GB of RAM memory. I currently have more than 700 GB of important data saved in that device.

I formatted it and chose the exFAT system.

I bought a Toshiba Canvio Basics external hard drive with 2 TB of storage some weeks ago.
