UPDATE: There is a NEWER cable that looks like it can transfer data from/to BOTH old-style OR Xbox360 "Slim" Hard Drives. Search for "Xbox 360 Hard Drive Transfer Cable" and the cable looks black instead of gray. It also has what looks like an added SATA connector for Slim style hard drives. Last I checked, that new product is here: Xbox 360 Hard Drive Transfer Cable ------ I received the Xbox360 Data Transfer Cable and used it to transfer all my data from my Xbox360 Elite console to my Xbox360 Halo Reach "Slim" console. Technically you are connecting ONLY the detached hard drive from your former console, hooking it up with this transfer cable, then connecting the other end to a USB port of the console you want to transfer data to. The cable comes in a box that is branded/designed the way all the new Xbox360 peripherals and games are showing up this year (those green "waves" and such). The process is very straightforward: (I did this while the Xbox360 Slim was already on, sitting idle in the 360 dashboard): 1. Connect one specific end of the cable to the detached, non-slim 360 hard drive. 2. Connect other USB end to any available USB port in the slim system (I plugged it into one of the two front ports) 3. A prompt will appear, asking if you want to transfer TO or FROM the console. 4. You can then individually select items to move, or move everything. One thing to note is that it transferred all my content to the Xbox360 Slim EXCEPT for games that were installed to the HDD (that is, disc games I installed to the HDD before for quicker access times). Not a big deal and it transferred everything else (some 800+ files) without incident. Remember that if you transfer data you still may have to "transfer licenses" - if you don't, then some content (such as downloaded XBLA games or other downloaded content) may not be playable if you aren't online and signed into Xbox Live. This isn't a big deal for me because I am always online when the Xbox is on. Do a google search for "xbox360 license transfer" and one of the first pages should be a link to the Microsoft page on the matter. This will move the actual 'licenses' over as well, allowing you to play your downloaded/purchased Xbox Live content when you are not signed on to the net. Additional note: you can only transfer licenses ONCE per year, technically. Then you just have to sit tight, or take it up with Microsoft via phone support (I can't vouch for having done the latter :) Like other reviewers say, once you're done with it... well that's it :( I'll be holding onto mine as I have friends transitioning their data from one console to another. That said, save money by just pitching in for one then and using it amongst your 360-owning friends :)
