Windows XP Pro SP3 32 bit on a Crucial M4 128 GB SSD (~70 GB for Windows System Partition). IFW 2.71 Differential Image Error when doing a Differential Image from a Full Image which was made with the 'Speedup Changes Only Backup' option. I got the error message (Insert media 2 containing file: file path,"filename.#1") near the end of running a Differential Image. My previous Differential Image (made a few days ago) gave no errors. I made a couple of more attempts to do the Differential Image and got the same error both times. I also got the same error on another PC. I made a new Full Image and did a differential of the new Full Image with no problems. What caused the error, how can I correct the problem and what does the error mean? If I clicked "OK" on the error message, the Image process would not continue. I had to abort making the Image. Thank you.
