I have a question that I don't see answered other places (incl. the drive upgrade guide).

I have a 2nd empeg as a backup unit. I'm moving it's disk (20GB model) into my primary MKII as a secondary drive, leaving my primary MKII drive alone. What, if any disk prep do I have to do on this disk? I know it's formatted but are the partitions already on it OK to use as-is? I'd love to save the effort of disconnecting my primary drive to run Disk Builder on it if it's not needed. Thanks.
