When I open armory the logs says it can find the data from the dir on the local disk. I couldn't get any links I found to work...how do I point it to my external drive.
Depending on the operating system, you first need to mount the disk.
Afterwards, start armory via the commandline with the
--satoshi-datadir parameter:
armory --satoshi-datadir="/your/path"
If you don't want to open armory via the command line each time, you also can edit the
armoryqt.conf by adding:
satoshi-datadir="/your/path"
