Well, I had two old HD's lying around from previous xbox's, and I wnat to use them in my PC so I thought I'll just install EvoX, unlock it, then viola! Format it with Windows. However, if I put either in, It gives me Error 06 which according to the Slayer's Manual, "Cannot Unlock Harddrive" Can anyone elaborate on that or give me a suggestion or 2? Thanks.

you need the motherboard that they were locked with to unlock them. or the EEPROM.

or use a chip to unlock them
