I dont understand these, I get them anytime I unrar, unzip, untar anything:

Cannot utime: Operation not permitted
Everything seems to still untar fine, but it feels liek it slows it down with constant messages about "Cannot utime: Operation not permitted"... Searching google groups it appears to happen when untarring to a non-unix partition, aka, FAT32

Also on another odd note, I have a 40gb partition that is FAT32 so winxp can see it too. Any file or folder I create there automatically goes all lowercase, whats the deal there?
