So I have a question here...but I need to explain my reasoning before I really ask it. OS X seems to be a god at doing this. I pop a DvD or CD into the drive, right click the disc on the desktop, right click the desktop - hit paste and the raw data is copied with no question asked. Once the original medium is removed from the optical drive, this "folder" of the disk remains as useful as the disc itself. If it's a dvd movie - it plays no problem in VLC or rips with Handbrake. If it's a CD - the AIFF's play and can be ripped in iTunes at a later date if you like to keep lossless music backups (*cough* audiophiles) So heres my question... can this be done with a Windows partition? Rather than make a disc image of say.. a 260 GB partition using 200 (wasting 60 GB in empty space while the image is made). technically.. can't I just copy the Windows disk and throw it into a backup on my HFS external HDD? It would only copy what's used. Then, if windows has a problem -- throw the Windows folder back into the disk repairing/replacing vital files any massive Windows-destroying damage it previously suffered? These files are raw, windows isn't running, so what's the harm in this? Of course good data or programs might not respond properly because the registry might not be up to key but they have cleaner/repairers for this and if this does work I'll just backup the registry more often. Hey I can even just add small changes I made to windows per my next backup, instead of making an entirely new backup. So why do people use disk images rather than this oldschool method of dragging and dropping? Wouldn't it be faster to drag and drop the windows into a new folder than waste time making a fancy mountable DMG? So thanks for reading my strange question though, hope someone can answer this for me.
