Bad Benq X360 drive

Hey guys I have two question. My moded benQ drive on my xbox360 kinnada got messed up during a recent upgrade. my computer crashed at the firmware write part and now i have a drive that the computer wont recgonise in win xp and the power lite keeps blinking. i tried all the possible methods available dosflash jungleflasher etc and cant get the drive to recgonise to be able to put frimware on it. I have ordered a sammy through ebay and was wondering if i can replace my benq with sammy MS28 TS-H943. here is my questions after reading many forms and tutorials.

1) i have the original drive key and fw, when i flash the new drive do i just replace the key for the new drive with the key from the old drive.

2) when i flash it do I put the ixtreme firmware for sammy or for benq on the new sammy drive.

any guidance or tutorials will be really appreciated.
