I have a USB flashdrive that has a boot disk and image on it. I am guessing there's a partition on there, even though I cannot see it. I have to reimage 30+ laptops and they're taking 40 minutes each. I have an additional 3 flashdrives (each 64gb, although the original USB shows the files as taking up about 38gb) which should make this a lot quicker. The problem is dragging and dropping all the files to the new drives doesn't create a workable boot/image drive, I've reformatted them (NTFS like the original) and tried to clone them using imageUSB but I get an error at the end saying it's out of space and the clone wasn't completed... when I try and use the flashdrive anyway, it has the boot piece, but not the image?! Does anyone know how I might be able to accomplish getting a complete clone of one 64gh flashdrive to 3 others, maintaining any (hidden) partitions and allowing the destination flashdrives to operate in the same way as the original (boot disk + image location)?
