Pirate from haxnetwork.net posted a tutorial how to decrypt a retail PS3 HDD. Here's what he posted:
1.) Make a dump of your PS3 HDD (connect to your PC via SATA)
2.) Plug HDD back to your PS3
3. Copy a large-dummy file to the HDD
4.) Unplug HDD from PS3, and plug it back into your PC
5.) Dump the HDD image againt, it
6.) Compare the two dumps you know have, and locate the encrypted dummy data (use HxD or any hex editor to do this)
7.) Replace the encrypted dummy data with sections of the data you want to decrypt
8.) Place the HDD back into your PS3
9.) Copy dummy data from PS3 to external media (USB drive/flash drive)
10.) Inspect the dummy file on PC from USB stick/flash drive.
Try it if you want, it's not confirmed yet.
