I have an external hard drive which I need to make an exact copy of, but I need to do so without leaving any trace of the operation on the original drive.
I'm primarily a Mac user, but I suspect the drive in question is formatted in FAT32, so if it would be easier to perform the operation in question, I have a Windows 7 platform as well.
My first question is, if I simply connect the external drive to my computer to check which file system is used on the drive, will this leave a record on the drive?
Second, what would be the best method of making a clone of this drive without leaving any sort of record on the drive itself? I was thinking originally of using Mac's Disk Utility to make a Disk Image of the drive. Would this work, or do you have a better suggestion using either Mac OS 10.7, or Windows 7?
NOTE: I should mention that I strongly doubt the Hard Drive in question will be subjected to any serious examination by professionals. I am more curious if the cloning would be evident to an average person using the tools available to them in either Mac OS X, or Windows 7?
