A:AnswerWhen you plug this drive into your USB port, you will have the option to open up a folder where you have files already saved... you just need to move/transfer them over.
It is done through the cable and there are detailed instructions, so very very easy to do.
A:AnswerYes you can. I have done this and it's a very smooth process. No programs or updates are required to be installed in order to use this external hard drive between PC and Mac.
A:AnswerYes, but keep in mind that due to the old FAT32 file system being the only common language between Mac and Windows, individual file sizes are limited to 4GB. If your goal is to transfer files from one computer to the other, you might be better off doing it over a local network if you're doing huge movie files.
A:AnswerYes,you can. If you connect it through your USB port and follow the instructions, it will work with Windows Vista. If your laptop is down like my laptop is, I found out that you can connect it as an external harddrive and use F8 to recover and transfer files before doing a factory restore.
A:AnswerDepend on how much space you used up on first backup. if there's enough space for your laptop, I think you can. As for Mac user, I know I can use two computers on same backup device.
