Assuming that the data in /home is important to you, I would recommend using a Linux file system rather than fat32. As Electro mentions and as explained in this article
, Linux file permissions aren't supported by fat32, and that to me would be a deal killer.
You could set up a small fat32 partition, and just copy files into it as needed, but I would not put my entire /home directory on that file system. Strictly my 2 cents, others may have different views. -- J.W.
