This data is saved and used while partitioning the disk. You edit the /etc/partitions file and get the whole disk accessible by rerunning mkpart and remaking the file systems manually. The better way is to circumvent the mapping done by the controller completely by installing a jumper at W14 on the WD1007A-WA2 (Sector translation enabled if jumper removed). This will allow the full disk to be seen when the install program reads the size of the disk, and you be all set. This is based on previous grief taking many hours and reinstalls to check results. Best of luck, and if everything works fine for you using this, post it as your running different software than I. Joseph Sarkes (junkyard!joe)
