HddHackr — how it modifies a Western Digital drive for use in an Xbox 360 HddHackr — how it modifies a Western Digital drive for use in an Xbox 360 Introduction This article is my attempt to understand the method by which HddHackr modifies a Western Digital drive in order to make it compatible with an Xbox 360. As I don't have an Xbox, or a supported WD drive, I'm relying purely on research. Therefore there may be errors. How HddHackr works HddHackr reads the HDD firmware version, serial number, model number, and capacity in LBAs from sector 16 of the original Xbox HDD, and then writes this information to a supported WD drive of equal or larger capacity. It does this by using WD's vendor specific commands (VSC) to modify the HDD's firmware. AIUI, in the case of a ROYL drive, the relevant firmware modules are 0D and 02. The result of this hack is that the WD drive then identifies itself in the same way as the original drive, eg Fujitsu MHV2020BH.

The WD drive's original modules are backed up in an UNDO.BIN file. LBAs 16 - 22 are referred to as the Hard Drive Security Sectors and are also copied from the source drive to the target drive. HddHackr backs up these sectors in a HDDSS.BIN file. The structure of the security sectors is described here: Here is an example for a 20GB Fujitsu HDD: Here is a hex dump of sector 16: HDDSS-20.BIN --- this file is a backup of LBAs 16 -> 22 0000 20 20 20 20 20 20 20 20-4E 57 35 38 54 35 41 32 NW58T5A2 0010 35 4E 48 50 30 30 39 33-30 30 32 43 46 55 4A 49 5NHP0093002CFUJI 0020 54 53 55 20 4D 48 56 32-30 32 30 42 48 20 20 20 TSU MHV2020BH 0030 20 20 20 20 20 20 20 20-20 20 20 20 20 20 20 20 20 20 3B 0F D7 3F-82 77 FE 41 C6 F6 A2 5D.?w.A.] 0050 FC 17 2C 17 7A D4 F8 D6-80 29 54 02 D3 79 C9 61.z.)T.y.a.

Over the past couple of months, I have been on a quest. This quest has led me to many different locales, and it is still ongoing. Unfortunately, my quest has hit a roadblock of sorts for the moment, but it has not ended. I will explain more on that in a minute, but for now, I wanted to document the things I have found out thus far. After hours of searching the net for a solution of using a Seagate hard drive in my Xbox, there was not a whole lot of happy news, however I have pieced together many sources, and have been able to change many of the drive’s parameters manually, effectively mirroring the functions of HDDHACKR. This is the main holdup that Seagate drives face. There is no automated way of doing this like there is with a Western Digital Drive.

Just for your information, the information in my post is not for the faint of heart, and you probably will kill your hard drive if you are not very careful. I take no responsibility for what you do to your hard drive. This is in no way a complete tutorial, nor can I guarantee that this will work for you. My hope is that someone will benefit from the information that I have pieced together. Even though I have not completed this project, I believe I have found enough information that someone somewhere will have better luck than I have.

It is about 2:00 in the morning as I finish typing this, and I am on my way to bed. This is a work in progress, so pictures will come at a later date. For now, I am happy with what has been written, and it will suffice for now.
