External hdd

Hi I recently purchased a iomega external hdd and i only have three usb port

all of which i am using.

One for the mouse

One for the keyboard, and one for the external hdd.

Sometimes I need to plug my bluetooth dongle in the usb port of the external

hdd, but when I want to safely remove the device it says "Close one or more

windows........"All programs are closed, and I have noticed there is a

logfile and another file that writes to the disk.Is there anything I can do

to stop windows creating a log file on the external hdd?

I have tried changing the security settings on the drive but I do not have

enough experience regarding this.

I plan on getting a usb splitter anytime soon but any help would be greatly

appreciated.

Kind Regards
