I have an HP Simple Save external hard drive with a Western Digital SATA HDD in it and every time that I connect the drive it mounts not only the drive; it also mounts an HP Launcher along with it. The list in Disk Utility is as follows: 465.8 GB Hitachi Mac2 465.8 GB Hitachi Macintosh HD 931.5 GB WD(My main drive for media and not the one of concern) The Grid 930.9 GB HP External HDD Media(THIS IS THE DRIVE) Untitled 767.2 MB HP Virtual CD 4607 Media(THIS IS MY MAIN ISSUE) disk4s0 HP Launcher PIONEER DVD-RW DVR-110D When I select the Virtual CD image, this is what the info says: HP Virtual CD 4607 Media USB External 767.2 MB Read Only CD Partition scheme Is there a way to completely reformat this HDD to remove that ridiculous HP Virtual CD partition? I was hoping to use this as a boot drive to replace the 500GB drive I have in their as my startup disk, but I don't want the HP Launcher included. Any ideas or advice? Thanks in advance!
