I have a number of flies that I am trying to copy from my iMac to an external Maxtor iTouch drive. The message that comes up is that the folder I am copying to cannot be modified. The external drive was used on my PC for storage of important data. Now that I came to my senses and got a mac my life has been easier, however this transfer of files has become an issue as my iMac drive is almost at its limit. The drive has not been formatted because I have all the data on it and I can access it with my iMac no problem. I have gotten info through Finder and it says I have viewing privileges only but under the permissions tab I have no lock icon to change that. Does anybody know what I must do?
