sdb (GAMES) is an ssd - samsung 870 qvo, rotational=0 - so unlike the two wd spinners there is no spin-down to gain from automounting it, and a steam library is better off never sitting behind a trigger. keeps nofail. dump and bak stay lazy. splits the old dataDrive helper into spinningDrive and eagerDrive and documents why each drive gets which. also records the steam gotcha found while debugging "steam library folder not writable": it was never a permissions problem - the drives are owned by uid 1000 mode 755 and were writable throughout. steam's fhs sandbox builds its bind list at launch by iterating /*, and /mnt does not exist on nixos until these fileSystems entries are activated, so a steam started before that has no /mnt for its entire lifetime. restarting steam is the fix.
