To be more specific, there is an area on the DMS that is before the first parition starts that phatnoise "hides" the DMS signature that is required for it to start the phatbox / keg.
If you reparition the drive with ANY TOOL other than the phatnoise DMS disc or our hack disc you will not leave that 1 meg gap and end up nuking your DMS signature. We have a way to bypass the signature to a certian degree but its only after you've hacked a phatbox with a working DMS and you have another signature you can write to a drive.
