I have a V1.5 xbox modded with x2.3 lite. Everything was working fine, was playing NBA ballers and I went to answer the phone and tripped over the wires and almost dropped the xbox but I was able to catch it before it hit the ground. Tried to turn it back on and now theres a weird noise and error code 7 on my tv. Took it apart and tried but still the same. The noise is from the hdd I found out, is there anyway to fix this? I have a spare HD thats about 10GB but I have no clue what to do since I can't access the retail drive. Can anyone help?

just swap them out really, then lock your new drive once it's in, i'd just use an auto installer if you just want to put the apps back on and such, should work out fine

test hdd in pc, find out what error 7 is
