IDE Drive changes ntfs permissions when attached to new PC

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.

I'm going thru a similar situation right now with one of my users on
XP Home. See what kind of encryption and/or protection scheme
the user's running.

on the users for the files (folder properties-security) do you have full permissions on "Everyone".. mind this assumes XP Pro on both..

if that is not set you will continue to have these issue.. But with XP home no answer..follow Brokencrow's line of thought..

The permissions don't change when you move that drive to another computer. The permissions are set using the user's SID. This SID is unique for each computer. Even though the username might be the same.

Not sure if this will work for external drives but you can set permissions on folders if you boot into safe mode. Normally Home edition shield this off. Set the permissions to Everyone Full control and you can use the drive everywhere.

You can also try to set the ACL on the commandline.
Something like this if the external drive is G:

Code:

cacls G: /T /G Everyone:F

Many thanks for all the helpful replies :) ntsf permissions do my head in! Well, not so much in XP but in Vista. There are times when it doesn't matter what I do, I can't move a damned folder or access it!

I am looking for a solution for Vista's Tantrums.. When the above happens there.. a restart is the workable solution (well it has been 100% for me.. but someone will prove me wrong)

Just a note - if you have a hard time using cacls I think it was replaced with subinacl
