If the external hard drive is formatted as FAT32, your iMac will probably be able to read it and write to it.
Otherwise, I'm not sure when it was Apple started shipping SAMBA with OS X, but if you go to the System Preferences app, and look at the sharing settings, if there's a "Windows File Sharing" option just start that service and you're good to go. Just create a simple network between your iMac and laptop, and transfer the files using Windows file sharing.
Now, actually using the files on the laptop is a whole different issue, which you're on your own for.
Hi, I currently have an Imac which runs @ 400mhz, 512 ram, its the brightly colored variety...
Well I'm getting a new laptop for college (Windows based) and I plan to get an external harddrive for all of my music and homework. The computer I have currently has ab out 4 GB of music stored on it, and also has a bunch of filed saved from highschool homework, lifeguard scheduling etc.
How can I easily transfer the files from my Mac to a PC or external harddrive formatted for windows? This is a onetime deal and then the mac is gone forever. Thanks for your help! : ) -Ben Stoviak
