This is a quote from 360 Mod Textbook on Hot Swapping the xbox DVD drive to update the firmware. Can it be updated this way? I don't need the connectivity kit? "ModeB Method 4 – Hotswap The fourth method of ModeB in fact is not a method to get into ModeB at all. The drive never goes into ModeB, but using this method, you will be able to flash your drive and since that’s what we are trying to do here, it is still included as a “ModeB method.” This method is not very applicable to many people so I won’t spend too much time going over it." "You need a SATA DVD-ROM drive hooked up to your PC and detected in Windows. This can be a normal PC SATA DVD-ROM drive like the SH-D163A or it can also be an Xbox 360 Samsung drive in 0800 mode. Whatever it is, it has to be a SATA DVD-ROM drive detected and working in Windows. Note your drive letter, then unplug the SATA cable from your “normal” drive and plug it into the Hitachi drive. You can then flash your Hitachi with that drive letter"
