I would like to dedicate over a terabyte of space to BIONC, but all that space is on my external hard drive, the F drive. My internal hard drives have 25MB between both of them, which is less than the default usage for BIONC.

How can I dedicate my F drive and it's storage to the SETI project through BIONC?

You can't - SETI holds all it data centrally and has many, many Tb of disks, in multiple arrays.
What you do however is use your computer to process some of that data - if you haven't already, join SETI@Home and start processing - you will be sent a number "tasks" of about 300k each, when you return the processed results you will get more tasks.

You may not have understood his request. He doesn't want a copy of all the SETI data. Especially not with only a terabyte of local drive space.

What you need to do during the installation of BOINC, is to install it to the drive you want to use for storage.

Yes, a terabyte of space isn't really necessary for Seti. Their normal tasks (Multibeam) are about 370KB big, while the larger ones (Astropulse) are 8MB. These latter ones aren't always available though and even if they are, very difficult to get as they're in high demand.
On top of that, Seti has a 100 task limit for CPU + 100 tasks per GPU. So even if you could get all these filled with Astropulse, you'd still only use 1.6GB.

Now then, onto moving the data directory.
First step: exit BOINC completely before doing anything. (BOINC Manager->Options->Other options...->check that "Enable Manager exit-dialog?" is checked->OK->File->Exit BOINC->check "Stop running tasks when exiting the BOINC Manager"->OK)

Assuming you're running Windows, use Windows Explorer to move the data directory with everything in it from the default directory C:\Programdata\BOINC\ to your F: drive, for example to F:\BOINC\
C:\Programdata\BOINC\ is a hidden directory, so make sure to set the Windows Explorer options to show hidden files and folders.

Next you'll have to tell BOINC that you moved the data directory, and to make sure that all the correct permissions are done, it's the easiest to uninstall BOINC via Add/Remove Programs, then reinstall it with the BOINC installer. (Which you can download from here. When you don't run projects that use VirtualBox, download the installer without it)
In the third screen in the installer, click Advanced.
In the window that comes up, change the second path at the top from C:\Programdata\BOINC\ to F:\BOINC\
Continue the installation.

There, done.

By the way, as you see in all my text, the program is called BOINC, not BIONC.
