Following this exchange, and some testing done with the trial version, I bought a R-Drive license. I am quite satisfied with it, I just have 2 new questions :
1/ I don't see removable media such as usb flash keys in the list of possible sources. Yet, it is sometimes useful to image them too. Is there a way to do do ?
2/ I have 2 recent usb flashkey, a HPv165w 8GB and an EMtec 4GB. They are both FAT32 formatted, and have over 50% free space. I can create a recovery media only with the Emtec, not with the HP. Is this normal ? It there a workaround to be able to use the HP too ?
