For the person that asked about USB key. For some reason, my key went bad just as I was about to use it so I had the floppy setup and ready to go. My original intention was to use the USB key. That's if that state was meant for me.
Well, I want to say I had success, and I did, but I had a minor problem happen and then discovered I lost a small part (and I'm upset about it).
So here goes, using the MS/Xbox Data transfer cable was the best option for the following reasons:
1) I did not void my warranty by breaking the seal on my 120gb hard drive, for which I only needed it to get a clean copy of the hddss.bin file.
2) Using Xplorer360 program (the latest version) and the data transfer cable, copying hex 16 -22 locations (which I was uncomfortable doing) was as easy as a drop down menu to 'copy hddss.bin'.
After I had gotten a copy of the hddss.bin file, I used hddhackr to place the signature onto the new Western Digital drive. When I did that, I did get the message that is was now ready for Xbox 360.
I tested it out and connected to my xbox 360 and it saw it perfectly, and I even formatted it without issue.
3) Having the Data Transfer cable allowed me to easily make a backup copy of the 120gb hard drive, using Xplorer360.
4) Making a backup of my 120gb hard drive meant I would not have to play around with winhex or anything else to get the missing partitions easily put back.
5) To get the partitions back, I just did a restore from the backup I make of the 120gb drive to the new Western Digital Drive.
This is when the problem happened and this was not a major problem.
I thought that after I did the restore to get the all the partitions back, that Xbox 360 would see the drive and be happy. But for some reason, and I believe it happened when I hooked it up to my Windows XP machine to do the restore, it saw it as a Western Digtial and maybe rewrote the signature back to the original, but I'm not sure.
So in the end all I had to do after restoring the drive was to run hddhackr once again. Hook the drive up, no need to format or anything else, all the data was there from my 120gb drive.
It was suggested that I should have save time to just do a restore from a smaller drive (in my case it would have been the 60gb that I was upgrading) and they probably in the long run were right. Since I had to run hddhackr over again.
So the only seal that was broken was on the xbox hard drive case that I was upgrading and not the 120gb.
So I only voided one xbox 360's warranty. That damm sticker, there is really no way to take it off without damaging it, they will always know it.
Now for my being upset with this. When watching the video on how to disassemble the hard drive case, they warn you to be careful not to loose the spring that is used to keep the drive in place when it's attached.
I almost lost the spring but managed to find it after it flew a few feet. However, I did loose the little plastic nub that was what you push to release the hard drive from the main unit of the xbox.
So does anyone know where to get that little piece of plastic, the nub or whatever you call it.
It might turn up but I think the dog got it!
So in the end, yes I have a working 120gb xbox hard drive that cost about $50 and then I spent another $15 on a Torx screwdriver set, but that will come in handy now and then.

PS The truth, when I ordered the Pro I did that to save some money, and I figured I'd do this upgrade and still spend less than I did on the Elite. But what I didn't realize until I got the Pro in the house, what that it did not come with the correct audio adapter if you are going to hook up the Xbox with an HDMI cable which I did (I had spare HDMI's laying around). The cost for the cable was $50 and it ended up coming with yet another HDMI cable that I did not need.
So total = I should have gotten an Elite to begin with. But then again, I would have had the fun I did all day today! I just wish I could find that plastic nub.
Ok it's here tonight, Xbox's New Experience, arriving at your doorstep tonight about midnight! Wow! I've been waiting for this!
