Wow.....20 Partitions, thats got to be a Record hehe
I myself have about 10 Partitions. 2 for Workbenches 3.1 and 3.9 and the rest are: Work - Work8......they are about 4 gig each (40gig HD)
WHy is your harddrive only 4200 rpm? is it a laptopHD? they finally got them in 100gb? cool...got to get me one........does the 8mb Cache speed up things?
Anyway.....there is a way to disable the HD's from OS3.9............Select WORKBENCH in the prefs and you will see the option "HIDDEN DEVICES" then just check off the ones you dont want to be seen........then save it like that and reboot. This is also good if there is content on one of the HD's that contains personall data that you dont want to be seen.
