Use the computer while defragmenting an external drive?

Ok,  here's a noob question.

Usually - and obviously - when I defrag my internal drive I don't use the computer until the hard drive is completely defragged to avoid writing any data to the drive during the process.

But my question is:  Is it ok to use my iMac while defragmenting a firewire external drive where no data is going to be written during the defrag process?  

Or should I just do the same and avoid doing anything on this computer until the process is done?

My problem is that my external drives are 1.5 TB and I have 7 of them so you can imagine that it takes a lot of time to defrag each one of them.

If this helps at all...  I'm using an iMac running OS X 10.5.7 and using drive genius to defrag.

Thanks.

I do it all the time i just my external drive for backup and storeing music and pictures.
Once it defraged it should not take long to defrag them again unless you delete a large file.

I don't know about Macs, but on Windows, you can even defragment a drive that is being used. Otherwise it would be impossible to defragment the system drive, except maybe at boot-time. Defragmenting one drive and using another one surely won't cause problems.

One other note you can connect more than one drive to your mac and defrag them at the same time to same time. You need a hub it you run out of port.  http://catalog.belkin.com/IWCatProductPage.process?Product_Id=193393
