A stupid question, assuming you're talking about the core qt wallet, you did start it from the commandline like this:
"C:\Program Files (x86)\Bitcoin\bitcoin-qt.exe" -datadir=d:\BitcoinData

(given that you're using windows, and d:\ is you external drive)

If you're talking about something else (the bitcoind daemon, linux,...): please give a bit more info

You can also right click on the shortcut and add the -datadir option to the command in the target box so that you don't need to start it from the command line every time.

Were there specific write permissions given for the drive? If you were using linux, filesystem permissions might not allow bitcoin core to write to disk. It might be also because of lack of space.

^^ This is a very good tip... I didn't even think about this one (yet). It's going in my private tips&tricks folder
