It's the same, but I see there were no replies
I'm not sure I understand the problem. Tell me if I have this right.
This computer runs XP Home and it is set up with multiple accounts for other users. The other users cannot open the C drive where the Operating System is. I'm not sure how that works, because even users with limited accounts should still be able to use their My Computer to see the hard disk, and if they cannot access it, then presumably none of their programs would work.
Do all these other users have full Admin accounts? If so, then any changes you make to the system, they can unmake.
If they have limited user accounts, then what you could do is hide all the files on the data partition, and limit the users ability to access or change folder options where they could unhide files. If they have full Admin access, then you can't do that.
I am using a computer with XP Home Edition on the C: drive. Recently added another drive with four NTFS partions, one of them is only for Data. Other users also have access to the computer and so have set up different accounts for them. Problem is, that they cannot open the C: drive but can see the Data patition. Downloaded Tweak UI to conceal this partition but it only conceals it from C: and not as required from the other Users. XP Home ED also does not seem to allow me to Hide or not share the partition. Can anybody help with suggestion??
