Hi iko22, here's my chckdsk info. Originally, I just went for chkdsk C: without switches which I've repeated again, and again with /r as shown below:

Chkdsk cannot run because the volume is in use by another

This volume will be checked the next time the system restarts.

I have no particular worries about leaving the PC running until my more urgent stuff is finished and all attempts to find the right solution fail or when there's no other choice but to reboot.

I'll respond to your other points and to other posters later... Thanks to all by the way!

Hi iko22

As you suggested, I've created a new System Image today. As soon as I can unmount my TrueCrypt user data drives later today, I'll make a new System Repair disk also. Edit: System Repair disk made.


Hi Megahertz07
I'm happy to say that I recently backed up my data anew, but thanks for the reminder.

Hi torchwood
Last time I looked, my Bios setup was absolutely normal, thanks. As far as I know a BIOS problem can't cause problems after a machine boots into Windows . . . or am I wrong?

So, once I'd completed my urgent stuff, I chose the inevitable route and rebooted the PC.

To my surprise - and relief - it began to load Windows right away, but stopped at the chkdsk c: /r I'd set as mentioned in my Post #12.

After this had completed and reported no errors, and Windows had stabilised, I found that diskpart once more showed Disk 0 and its partitions under list disk and list partitions.

Not only that: Disk Management was also back to normal and showed all drives & partitions as normal.

Why Disk 0 had disappeared from view suddenly from these utilities I'll never know, but all's well that ends well.

Many thanks to all who helped me to arrive back safely at this satisfactory state of affairs!
