Team MODFREAKz released a new version of HDDHackr, a tool that allows you to use some Western Digital HDDs as Xbox 360 HDD.

What's new/fixed:
* SATA and IDE port scan improved (The ports are now enumerated with the CONFIG_ADDRESS and CONFIG_DATA register instead of using interrupts)
* PATA and SATA controllers list updated
* Automatic Device Reset
* Code optimization to work with modern SATA2 controllers added (Remember to set SATA controllers to IDE and not AHCI mode)
