Drive isn't connected?

Hi - since upgrading to MacOSX from Leopard to Snow Leopard, my WD My Book Studio Edition 1tb drive doesn’t seem to be connected. Been fine since Aug 2009, do i have to get upgraded software for my WD drive for it to work or should the existing software still work? Thanks … I can’t remember if my drive came with a CD or not …

Hi there! Is the drive seen on disk utility? And which MBS do you have, the old one or the new one? o.o

Hi there, The drive does not come with CD is plug and play like a memory stick. Look for the drive in Disk Utility and try to run First aid on it if is showing there.
