Hi there! I'm trying to migrate my windows xp computer to my mac laptop using Parallels Transporter Agent, via an external storage device. In the early stage of the process, I am informed that 40 Gb of free memory will be needed. This number is in agreement with the size of the windows partition that I have (5 Gb free space in a 45 Gb partition). However, I have tried the migration for a number of times using an empty 120 Gb external disk and the process always fails because the disk gets filled! Has anyone been through the same? How can I overcome this? cheers, Edward
