I think I found something here: "once u get that message power off the pc remove the hard drive... (DONT POWER IT ON AGAIN WITH THE HARD DRIVE CONNECTED AFTER U POWER IT OFF)
Reason for this is because most modern motherboards inculiding my gigabyte p45 with ICH10 southbridge create that measly small 2mb hpa at the POST process which i thought was created by Western digital... so my appologies for previously stating that it was created by western digital.
Hope this helps many of u... It took me a freakin month to really figure out what is going on with the drive. "
Great now I keep getting, "No ATA devices present!"..... trying to hddhackr on the new drive to UNDO.BIN again since it didn't run the first time. It sees it in the BIOS....
ok, it recognizes the original 120gb drive in hddhacker, but not the 320gb........
Hmm it picked it up after I did the other one, thank god LOL
OK I figured it out.
My gigabyte motherboard did in fact play a role.. It does add HPA and change the LBA.
This time after I flashed, I popped it right into the Slim, and it is visible has a HD with 228gb free.
So now I just have to plug it in once in Windows to avoid HPA when booting up.
however, I just plugged it in and it isn't detected....it has to be there on boot i guess UGH!!!!!!!!!!!
I'm also going to use Xport 2.12 or w/e instead of Xplorer this time.
Now one question remains: how do I wipe and flash the original 120gb drive since it now has HPA?
AH HAH!!!!!!
I needed to read all of this, and now will be able to remove HP F-ING A!!! and everything will work!
"Ok guys. I have some amazing news I got the sucker to b working. Here is how.
This is for all of you guys that have the firmware flashed but keep getting the LBA does not match error
The tools that i used were hddhackr 0.91b and MHDD as discussed in a post in this forum.
Here is what i did... I used hddhackr to flash the fw and it does the whole conversion but because of the difference in LBA, it wont say the drive is compatible with 360 and even if u try after that the 360 wont recognise it.
So this is what u do. Flash it.. reboot, run MHDD and in there you select your drive.. It will appear as fujitsu, and then u have 2 handy options from the many that u can use. #1 is rhpa (shows u the hpa size... what is the factory and what is user accessible) and the 2nd 1 is nhpa which removes the hpa present on the drive that causes the lba size mismatch.
For those of u that dont know what hpa is wikipedia explains it way better than me so wiki "host protected area"
once u try to remove hpa odds r that it will fail... Dont worry. Unplug the power from the hard drive (THE POWER ONLY NOT THE SATA) wait 10 sec and plug it back in and try nhpa again and it should work. that will remove the hpa and have the whole lba accessible to the user. once that is done just type exit and u will b back in dos.
To verify that this works, simply re run hddhackr 0.91b again and select the drive and it should tell u that u can run it.
once u get that message power off the pc remove the hard drive... (DONT POWER IT ON AGAIN WITH THE HARD DRIVE CONNECTED AFTER U POWER IT OFF)"
