Hi I'm trying to help someone who has a problem with connecting the same drive to a different PC and finding that he has to reset ownership each time. The other PC is running the same OS, same formatted drives ie Windows XP SP3, the drive is always secondary slave, and always the D drive whichever pc it's on. He has admin permissions on both PCs and advanced file sharing is enabled on each. Is it possible that the system on the new PC is reclaiming ownership when he attaches the drive? I just can't think of any other solution.
