Re: How to find out all drives in NT2000 using command line? Thanks

Hi Frank,

There is no command that I can think of that does this; you'd have to write a program or script to do it. Here are sample script and C++ program (they both do the same thing). If these are useful, tailor as you wish.

Regards,

Andy

WMI SCRIPT

' ListDrives.vbs
' Invoke by running
'
' cscript ListDrives.vbs
'
' from an OS command prompt.
strComputer = "."

set objWMIService = GetObject("winmgmts:" _
& "{impersonationLevel=impersonate}!\\" _
& strComputer & "\root\cimv2")

set disks = objWMIService.ExecQuery ("select * from Win32_LogicalDisk")

for each objDisk in disks
select case objDisk.DriveType
case 0
' I would not normally expect to see this.
Wscript.Echo objDisk.DeviceID & " Unknown"
case 1
Wscript.Echo objDisk.DeviceID & " Invalid root path"
case 2
Wscript.Echo objDisk.DeviceID & " Removable"
case 3
Wscript.Echo objDisk.DeviceID & " Fixed"
case 4
Wscript.Echo objDisk.DeviceID & " Remote"
case 5
Wscript.Echo objDisk.DeviceID & " CD-ROM"
case 6
Wscript.Echo objDisk.DeviceID & " RAM disk"
case Else
' I would not normally expect to see this.
Wscript.Echo objDisk.DeviceID & " ??????"
end select
next

C++ PROGRAM

/*
ListDrive.cpp

Compiled with Visual Studio .Net 2003 from an OS prompt as follows:

#include <cmath>
#include <iostream>

using namespace std;

int main()
{
char driveLetter[] = "*:\\";
DWORD drives = GetLogicalDrives();
DWORD bit = 0;

if (!drives)
{
cout << "ERROR: GetLogicalDrives() failed with rc "
<< GetLastError() << endl;
return -1;
}

for (int i = 0, bit = 1; i != 26; i++, bit *= 2)
{
if (drives & bit)
{
cout << char('A' + i) << ": ";
driveLetter[0] = 'A' + i;

switch (GetDriveType(driveLetter))
{
case DRIVE_UNKNOWN:
// I would not normally expect to see this.
cout << "Unknown";
break;
case DRIVE_NO_ROOT_DIR:
cout << "Invalid root path";
break;
case DRIVE_REMOVABLE:
cout << "Removable";
break;
case DRIVE_FIXED:
cout << "Fixed";

cout << "??????";
break;

cout << endl;

} // for (...)

cout << endl;

return 0;
}

The only dumb question is the one that goes unasked.
The command line is your friend.
"Good enough" is the enemy of excellence.
