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.
