you can symlink the compatdata and shadercache to different disks, but keep in mind that if you disconnect your disk then, all games symlinked to that disk will fail to start with no error
you dont symlink them, you connect the disk you want, format it the way you want then go to that page in steam settings and add the disk as a steam library
symlinking the game assets to other disks causes more issues than what you think they solve. you will end up slowing down loading in the games to whatever the slowest disk is, it can even crash some games
enough with going around circles avoiding that exact thing im looking for, so help me with symlinking the game files im totally aware of riskes comes with but just making my money worth of drive to be fully used to do the job i seek.
