Dido,Ive always used Imation floppies, but if the data is valueable. Stay away from floppies. Ive lost projects and a nights worth of lab work because a floppy got bent in my bag. Zip disk are way tougher, but a usb key drive is SO wonderful. Plugs into everything. Everythings got usb, no compatibility issues. Unless using old windows and need drvs.
Given um to all you employee's , they will be psyched and will have NO excuses!!! anymore.
