hard-disks and folders cannot be set to 'read only'. That attribute applies only to files. I'm curious to know how you discovered that the entire C drive is 'read only'? If you right-click on the drive and choose 'properties', there is nothing to see regarding the drive's read-only status. If you look at the properties for any folder, there is a 'read only' option but it's disabled, as indicated by the solid square. This means that folders cannot be made read-only.
Recently I tried to run my Autocad program. It faulted on an error stating that it couldn't create files in the Temp directory and that I should check to see if it was marked Read Only. I found that the entire drive is marked Read Only. When I went to Properties and tried to reset it to normal it went right back to Read Only. I was able to create a new Adminstrator User on my PC to get around the problem, but that means all my user settings are lost. It appears that I have lost administrative rights to the drive. All my other apps seem to work fine. How do I correct the problem without loosing my current user configurations. Why doesn't Windows XP allow one to copy or save a user configuration?
