Where does Windows remember hard disks?

Somewhere in Windows is a place where hard disks are remembered. I know this because if I wipe the C: drive on one of my editing computers and reload it (to keep it fresh) then each time a different caddy is inserted this new installation says "Hello - haven't seen you before. I'll need a reboot before you can be used" (or words to that effect). Now, with 50 or more caddies this can get a bit tiresome. Is it possible that the information is stored in a file that could be pasted into a new installation?

Incidentally, Windows also remembers the drive letter that the HDD was given when it last worked with Windows. Since I do a lot of drive letter shuffling maybe that information is also stored in that same file?

Hi
Of course I haven't the slightest clue about the answer to your problem, but the Mac community have identified some of the quirks in Windows disk file system whereby it isn't safe to allow an NTFS drive to be altered outside of a Windows installation because Windows can't keep track of the new data, and rejects it.
There are some low-level highly proprietary data-integrity routines built into Microsoft's code that you mess with at your peril... ;)

So any attempt to interfere with the way Windows identifies a drive (and more importantly, the data on it) should be rigorously tested with test data before being tried with real-life files.

I have loads of caddie and the PC never asks for a re-boot before use, even if used on different PC's, are the caddies system ones or data ones, Ray?

Paul - Thanks for the warning.
Z - Data caddies. It's not every time, just the first time that a drive that Windows hasn't seen before is introduced.

windows checks the 8 character hex code used for system identification

dir c:
Volume in drive C is harlequins_os
Volume Serial Number is 94AF-C377

the same code is / was used by Pinnacle software to generate the unlock codes against a serial number
