@DRIVETYPE shows IMDISK as 3 Fixed Disk, not 6 RAM Disk

TCC  24.02.48 x64   Windows 7 [Version 6.1.7601]

I am using IMDISK;

c:\users\jlc\utils>imdisk --version
Control program for the ImDisk Virtual Disk Driver for Windows NT/2000/XP.
Version 2.0.10 - (Compiled Nov 25 2018)

...to create a RAM Disk;

@setlocal
@echo off
iff exist t:\ then
  echo T: Drive already exists
else
  imdisk -a -s 512M -m T: -p "/fs:ntfs /q /y" -o awe
endiff
endlocal

...but @DRIVETYPE returns 3 Fixed Disk instead of 6 RAM Disk.

c:\users\jlc\utils>echo %@drivetype[t:]
3

...and I am not sure why.

@DRIVETYPE simply calls the Windows GetDriveType API. You need to talk to your driver developer.

Same with the Windows PE RAMdisk.

In 2009, Steve Fabian reported the same with regard to Qsoft's ramdisk (claimed to be based on MS's published method).

SoftPerfect RAM Disk

[…]$ tcc /C echo %@drivetype[W:]
3

Windows 10 has:

1. c:\windows\inf\ramdisk.inf
2. c:\windows\system32\drivers\ramdisk.sys
3. HKLM\System\CurrentControlSet\Services\Ramdisk

Does anyone know what they are all about?

They are for iSCSI ramdisk: target.
The logic is, you create a `ramdisk:…` target, then make a client connection to yourself and use it as your local disk.
