So, I used Partition Wizard to do what it said was moving the extra space from the sixth partition to the primary partition, which is in position #4. The files on it still take out the same space as on the internal. It was migrated over as 33.4 GB, increased for some reason. The sixth of the six partitions is the main 15.76 GB Recovery partition on the internal drive. But the Normal compression for the Image needed 83 GB, so I realized in my first failure for lack of space.

I am trying to make the Windows 10 Image to the primary partition on the external drive, which had 81 GB of free space on it. What was odd is that it enlarged some of the smaller partitions, while reducing the primary partition. When Partition Wizard migrated the files, it changed the size of partitions so they would fit on the smaller external drive. I used an application called Partition Wizard to migrate the Windows 8.1 files over - they are pretty much a clone, as if I migrate them to a USB flash drive, it will boot. One of the partitions is hidden, the 128 MB one that presumably is for the Master File table. It has six partitions on it (and so must be GPT, not MBR), made when I migrated over the drive from my previous Windows 8.1 installation - and I want to keep those if possible. (The internal drive is SATA.) It is a GPT disk.

The external drive is an IDE drive connected via USB. To explain all the complexities - and there are plenty: Why? What can I do to solve this problem? Acronis gives no idea whatsoever how much space it wants - a serious failure of information. But every time, Acronis gets nearly all the way through doing it, and then craps out, saying there is not enough space. I am running Acronis True Image from a booted DVD.Įven via the normal compression, Acronis indicates the final image will be about 83 GB, and the free space it is going to is 99.5 GB. I have tried it at both normal compression and maximum compression. But Arcronis True Image 2016 keeps saying there is not enough space on the partition where I am trying to put the Image, even though the OS and Acronis True Image 2016 (64 bit) both indicate there is much more than enough free space on that partition for the size Acronis says the final Image will be. I have been trying to make an Image of my internal Windows 10 drive to an external drive.
