Wow - that's just strange. Gotta love Windoze, don't you?
One comment was certainly on target:
"How in the world does Windows 8 wind up thinking that the internal drive and the USB drive have the same Unique ID??? That kinda seems like a MASSIVE flaw"
For anyone else who sees this Windoze2GO behavior, here is method that Microsoft specifies to check the ID of both the drive and device. What you do NOT
want to find is that they match!:
- Open diskpart.exe
- Type "list disk" to determine the disks in the system.
- Type "select disk #", to select a disk.
- Type "unique disk", to view the unique ID of the selected disk.
Not that this explains how these machines are suddenly coming to think they're 2GO machines to begin with, which is another problem altogether (a bit of a double whammy for the user).
What I don't like, but suppose we'll have to live with for now, is that it takes some work with REGEDIT to kill the 2GO feature of the machine. Here's what Microsoft had to say about dealing with that, and also about the modification of the ID for the TomTom device (I have swapped the phrase "USB Disk" for "TomTom" in each case):
Follow these steps to delete the Windows To Go registry value:
You will most probably notice that the issue reappears when you connect a particular TomTom to the PC. Subsequent removal of that TomTom will cause the PC to crash. This is happening because the unique IDs of the TomTom and the internal HDD are the same. The easiest way to fix this issue is to "clean" the TomTom. A clean will destroy all data on the disk, so back it up first.
- Open regedit.exe
- Browse to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control
- Delete this value: PortableOperatingSystem
Restart your PC.
Of course, we would also insist that the user make a full backup copy of the device before doing any reformatting!!! Consult our tutorial here https://www.tomtomforums.com/t17864-how-backup-contents-your-unit-computer-how-restore.html before you even start that procedure!
- Open diskpart.exe
- Type "list disk" to determine the disk number of the TomTom.
- Type "select disk #", where # is the disk number you determined.
- Type "clean".
- Type "exit".
I doubt you will be the last to report this, so we'll keep that link you left us at the ready.
