Thanks in advance for any help you can offer. I've got two Xboxes, one for me, one for my son. Both have been softmodded with SID5 using the 007 method. Both have unleashX. For each one I've backed up the eeprom, c drive and e drive and have them saved on my pc by FTP. I used Xboxhdm_v1.9, added my eeprom and c and e drives and created an iso for each xbox (using the drives and eeproms from each to make a matching linux.iso). I have two Maxtor 80gb hard drives. I used Xboxhdm_v1.9 to format each drive, step by step according the the tutorial. I then locked each drive using the "lockhd -a" method and both said that they locked. Both Xboxes still work fine with the original hard drive. I then put the new hds in their perspective Xbox. My Xbox gives me an error 13, my sons gives an error 6. Both systems had the most up to date dashes on them. I can obviously start all over but would like to know what went wrong with each one so I don't do it again. Again, thanks for any help you can offer.
