please excuse the beatles lyrics above... anyway i need a way to put another xbox hdd into my xbox without soldering or a mod chip because i'm cheap and bad at soldering. can someone help?

either softmod your xbox then hotswap your HD or get a cheap chip and get someone to solder it in
for ya or do it your self (aint hard) or get a solderless adaptor.

If your Xbox boots, or you have the eeprom, you can softmod.

If your Xbox won't boot due to the HD is dead, you need a mod chip.
