I have an 80GB external hard drive which I can connect using firewire or USB 2 and either way if I try to copy and paste an Acronis image from drive D to the external drive I keep getting the message that there is insufficient space on the external drive to do this. The image is in 2 parts and totals 7.25 GB but even if I try to copy only the first part of the image which is 4 GB or the second part which is 3.25 GB it says I have insufficient space on the external drive even though there is 40 GB of free space. This happens even after running a check disk to fix errors on the external drive. It happens no matter how many check disks I do. There appears to be something peculiar about the format of Acronis Images that causes the computer the computer to think there is not enough space on the external drive to copy and paste the image when there is in fact 10 times the required free space. Has anyone else experienced this or is it something wrong only with my computer? I can by the way copy other large files to the external hard disk as I just copied and pasted a 4.12 GB file to the drive but just prior to doing this the Acronis Image could not be copied and pasted.
