Here’s a video posted on Youtube by SiddGoneWild that shows the old HDDs from the Original Xbox 360 will work just fine on the new Xbox 360 S. You’ll have to strip the HDD from the original HDD-case and slid it into the 360 S HDD-port. Not ideal, as the Xbox 360 S proprietary port is much larger than the 2.5″ SATA HDD, but it will fit in (SATA data/power ports match the standard) without needing any 3rd party hardware addons or so. I’d just suggest to add some rubber tabs on the sides or so to prevent the HDD from moving too much.
I assume laptop/PC HDDs modded with HDDHackr(info) will work just fine in the Xbox 360 S as well (and save you a small fortune). If anyone tried this already, let us know in the forum thread below

Somski released a new version of Xbox 360 ISO Extract:
[QUOTE]
This program allowes you to extract multiple xbox360 isos based on exiso(info).
+ you can scan recursively through a directory and pick every iso (every iso must be in a seperate dir)
+ each iso will be extracted to the target_dir\where_the_iso_is_located_in
+ skips extracting if target_dir already has the directory
+ “remove iso afterwards” functionality (be careful! maybe some bugs)
+ statusbar and log window
+ automatically deletes the $SystemUpdate directory (since it’s not needed)

What’s new/fixed:
+ order of the queue is changeable now
+ last iso and extraction dir are saved now
+ scans the iso directory on change and startup (needs a bit longer to load)
* some error handling added
