I have a 320GB external hard drive from WD which I was using to back up my personal laptop running XP Pro. My laptop has since crashed and I need to access the files on my external while the laptop is being repaired. I have a laptop from work running Vista and the external does not show up in My Computer when I plug it in. I suspect this is because the work laptop's cd drive and my external both have the E drive letter. My question is this: is there a way to access my files on the work computer without formatting the external and losing all my backed up documents? I am under the impression that giving my hard drive a new letter will require it to be partitioned/formatted?
