Slave drive permissions

I wasn’t certain exactly where I should make this posting. I am running XP Home on a Dimension E 510. The O/S on the Western Digital 80G drive was wiped out by an attempted back up using Norton Ghost 2003.  I have installed a new Seagate ST136081AS 160G drive and XP Home and all drivers. The good news is that the machine is back up and running. The bad news is the O/S is recognizing the old drive and the fact that there is data on the drive that is still protected with file permissions. I can obviously alter the security and sharing properties for each of the 5 users. However, that would take far too long in my opinion. I have tried running Sysinternals PsPasswd utility with no success. It looks like that utility will only remove/change permissions and passwords on the bootable drive. Please correct me if I am wrong. I am at whit’s end here. You have to install the utility from their site in order to access the commands I think.. So far I have only been able to alter current permissions and password on the primary drive C: Does anyone know how I can regain full access to the data on the old non bootable slave drive. I have tried to boot that drive in safe mode and every conceivable way. It always comes back with “Missing O/S” Like I said earlier; I know the data is still there on that slave drive. It’s just a matter of regaining access so I can transfer the data. The commands I have been using are associated with a utility from microsoft sysinternals site.
