I have Built three puters in last few months using AMD 64 Cpus's, different mobo's and Cpus but all the using hatachi SATA HD's. All three systems show at bottom by the clock the "safe to remove" USB icon, i click on to see what it is and they all show it as the HD. 1 system runnin RAID so it show 2 dives...Is this normal, if no what to do....If yes how do i hide the icon?
