I just noticed that Administrative Tools'Disk Management screen shows these inaccessible partitions as being formatted NTFS (which is true), but when you right-click for Properties, it lists the file system as "RAW" and shows no free spaces (both if which are NOT true).
I am stumped.
I was running Windows 2000 Pro, then deleted it and installed Windows XP Home.
My computer had and still has has three hard drives: (1) a SCSI (SATA) partitioned into C: and E:, (2) a SCSI (SATA) partitioned into D: and G:, and an old IDE drive used as F:.
Under Windows 2000, people could sign on as "Guest," but they had access only to parts of Drive C: All other drives could be accessed only by me, "Administrator." (I set this up so long ago I don't remember just how I did it.)
Now when I sign onto XP an administrator, I'm denied access to all the partitions except C: and F: ("E:\ is not accessible. Access is denied.")
I can't just repartition and reformat; tons of data are in those partitions.
