Many people believe that the swap needs to be on the same drive. That's not accurate though.
I have mine on my G drive which is a SATA II Caviar Black 1TB drive, attached to a controller card.
My OS (system and boot) drive is D, which is attached to the motherboard and is a WD 400 GB drive.
My pc creates minidumps fine....well up until a week a go when I stopped having them after I helped MOTU repair something in the driver for my Traveler professional audio interface.
(I would get bsod for years every few days showing MOTUfwa.sys)
Now it's all smooth sailing since they repaired the errors I've shown them in dumps.
