You really need to be asking these questions in the other forum bro but anyways...
When you lock a hard drive in an xbox: that hard drive is matched to that xbox. You can't take it out and put it in another xbox and have it work without first unlocking it.
The retail MS bios requires that your hard drive be in a locked state to operate...
What you seem to be saying is that you took a standard hard drive out of a different xbox and put it in your xbox WITHOUT first unlocking it on the other xbox and then not locking it on yours after you transferred it. If the chip was off and the machine booted with an unlocked drive that was from another xbox then the TSOP on your motherboard has been flashed and you need to reflash it with the MS bios. The only way that other xbox drive could have booted in your xbox was if your tsop has been flashed with somehting other than an ms bios. The hard drive you transferred HAD TO BE UNLOCKED ON THE OLD BOX AND THEN LOCKED ON THE NEW BOX or it would not have worked.
Modchips do not require the hard drive to be locked in order to run. Your hard drive only needs to be locked if you are using MS BIOS with modchip off and/or intend to play on XBL.
