[QUOTE="smittio, post: 809546, member: 88800"] I was having the same issue: The USB Memory Stick would get mounted on Mac, and "in use" -- so that Windows could not mount it. I got an error, something like, "the device is in use, please remove it and try again", but because it was formated as FAT 32, it didn't show up on the Mac desktop, so how to unmount it? Answer: Fire up Terminal, (in your applications folder) and use the command line interface to Diskutil. "diskutil unmountDisk /dev/disk3", substitute your disk number. check the listing to see which disk number is in use for the usb drive, (go by the size). [INDENT] Macintosh-4:~ jjs$ diskutil list /dev/disk0 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *93.2 Gi disk0 1: EFI 200.0 Mi disk0s1 2: Apple_HFS Macintosh HD 92.8 Gi disk0s2 /dev/disk3 #: TYPE NAME SIZE IDENTIFIER 0: FDisk_partition_scheme *1.9 Gi disk3 1: Windows_FAT_32 UDISK 1.9 Gi disk3s1 acintosh-4:~ jjs$ diskutil unmountDisk /dev/disk3 Unmount of all volumes on disk3 was successful Macintosh-4:~ jjs$ [/INDENT] now you can switch over to Parallels, and use the "Devices" menu to turn on the USB drive. all worked from there! this site was very helpful, and has some niffty tricks to make a bootable stick!
