Here are some quick descriptions/explanations I found on the XS forum that I find useful.
Xbox Live is now checking each Xbox to see if the hard drive has been replaced.
If your hard drive is any different than the one it came with, you will be
banned, even if your new hard drive is locked.
This file is a disassembly of Xbox Live's security code as of today (March 6,
2004), and it shows that Microsoft is directing Xboxes to send their hard drives'
identification back to Microsoft.
Note that at this moment I can't say yet if Microsoft is banning people based on
their HDD. There are lots of theories and ideas about what Microsoft does or
will do with this HDD-information and only the future will tell. At this moment
many people with large HDD inform us they are still on LIVE while a few also
told us they got banned.

You can't boot a system with the original (unmodded) BIOS if the drive
is not locked, therefore you can't play Xbox Live.

The master passwordd is TEAMASSEMBLY case sensitive if you used ConfigMagic
to lock or unlock a drive. If you put your Xbox hdd in your computer and
make a ms dos boot disc with the unlock/lock tools and atapwd (not necessary
but very usefull). Boot up with dos floppy you made, you can run the
hdunlock.exe and use master passowrd TEAMASSEMBLY (case sensitive) then run
hdlock.exe your Xbox hdd will be unlocked.

HDD "frozen" (security feature) means the drive will refuse to accept any
Example: An unlocked hd that is "frozen", set a password and reboot, the drive
is still unlocked, no password is required.
ATTENTION: Don't play with passwords, it could make your drive useless!
Some manufacturers seem to set their drives to "frozen" by default, there's
also a chance that some mainboards do this while booting.
Reason: To prevent accidential setting of a password (if you cannot set it,
there's no risk of forgetting it).

Can't Unlock Xbox Hard Drive?
Ever had an Xbox hard drive which didn't work as it wouldn't unlock and you didn't
have the original eeprom / xbox to unlock it?
Well it seems one of our forum members has found a utility which removes ata
passwords from a huge list of compatible hard drives and we have had many members
test this with 100% success.
The downside at the moment is that you have to buy a "recovery licence" for a
small fee for $50 but when you have a 160GB drive with all of your data thought
to be lost it seems almost irrelevant.
