54} How can I get the type of a disk device?
The following code will list all the devices that
are present and their types. Requires administrator privileges.
@echo off & setlocal enableextensions
(for %%d in (A B C D E F G H I J K L M
N O P Q R S T U V W X Y Z) do ^
@fsutil fsinfo drivetype %%d:) ^
| find /v "No such Root Directory"
endlocal & goto :EOF
The output might be e.g.
C:\_D\TEST>cmdfaq
A: - Removable Drive
C: - Fixed Drive
D: - Removable Drive
E: - Removable Drive
N: - Removable Drive
Z: - CD-ROM Drive
Anoter method, another PC
@echo off & setlocal enableextensions
set temp_=%temp%
if defined mytemp set temp_=%mytemp%
set outfileUnicode=%temp_%\infou.log
set outfileAnsi=%temp_%\infoa.log
"C:\WINDOWS\system32\dllcache\msinfo32.exe" /report "%outfileUnicode%" /categories +componentsstoragedrives
type "%outfileUnicode%">"%outfileAnsi%"
findstr "^Drive ^Description" "%outfileAnsi%"
for %%f in ("%outfileUnicode%" "%outfileAnsi%") do if exist %%f del %%f
endlocal & goto :EOF
The output might be e.g.
Drive A:
Description 3 1/2 Inch Floppy Drive
Drive C:
Description Local Fixed Disk
Drive D:
Description Removable Disk
Drive L:
Description Network Connection
Drive N:
Description Removable Disk
Drive P:
Description Network Connection
Drive T:
Description Network Connection
Drive Y:
Description Network Connection
Drive Z:
Description CD-ROM Disc
For more comprehensive information we could substitute the following
findstr line into the code
findstr "^Drive ^Description ^Size ^Free\ Space ^Volume\ Name" "%outfileAnsi%"
Utilizing Visual Basic in the CMD script we have the following option:
@echo off & setlocal enableextensions
:: Build a Visual Basic Script
set skip=
set vbs_=%temp%\tmp$$$.vbs
findstr "'%skip%VBS" "%~f0" > "%vbs_%"
::
:: Check the usage
if "%1"=="" (
echo Usage: %~f0 [DiskDevice:]
goto :EOF)
for %%d in (a: b: c: d: e: f: g: h: i: j: k: l: m: n:
o: p: q: r: s: t: u: v: w: x: y: z:) do (
if /i "%%d"=="%1" goto _set)
echo Usage: %~f0 [DiskDevice:]
echo The DiskDevice must be A: - Z:
goto :EOF
::
:_set
set drive_=%1
::
:: Run the Visual Basic Script
for /f "tokens=*" %%t in ('
cscript //nologo "%vbs_%" "%drive_%"') do (
set drivetype_=%%t)
for %%f in ("%vbs_%") do if exist %%f del %%f
::
:: Show the results
echo Drive %drive_% is of type %drivetype_%
endlocal & goto :EOF

'The Visual Basic Script

Dim FSO, drive, d, dtype 'VBS
Set WshShell = WScript.CreateObject("WScript.shell") 'VBS
drive=WshShell.ExpandEnvironmentStrings("%drive_%") 'VBS
Set FSO = CreateObject("Scripting.FileSystemObject") 'VBS
If Not FSO.DriveExists(drive) Then 'VBS
dtype = "Not found" 'VBS
Else 'VBS
Set d = FSO.GetDrive(drive) 'VBS
Select Case d.DriveType 'VBS
Case 0: dtype = "Unknown" 'VBS
Case 1: dtype = "Removable" 'VBS
Case 2: dtype = "Fixed" 'VBS
Case 3: dtype = "Network" 'VBS
Case 4: dtype = "CD-ROM" 'VBS
Case 5: dtype = "RAM Disk" 'VBS
Case Else dtype = "Not recognized" 'VBS
End Select 'VBS
If d.IsReady Then 'VBS
dtype = dtype & "; Ready" 'VBS
Else 'VBS
dtype = dtype & "; Not ready" 'VBS
End if 'VBS
End If 'VBS
WScript.Echo dtype 'VBS
The output could be e.g.
D:\TEST>cmdfaq P:
Drive P: is of type Network; Not ready
A pure script method, but (again) requiring administrator privileges, to test
e.g. for a CD-ROM drive is
@echo off & setlocal enableextensions
(fsutil fsinfo drivetype Z:|find "CD-ROM Drive">nul)^
&& echo Z: is a CD-ROM Drive || echo Z: is not a CD-ROM Drive
endlocal & goto :EOF
The output could be e.g.
D:\TEST>cmdfaq
Z: is a CD-ROM Drive
A related question. How does one detect the drive letter of the
CD-ROM drive on a PC? This method works only if you are logged on as
"an administrator or a member of the Administrators group".
@echo off & setlocal enableextensions enabledelayedexpansion
for %%d in (C D E F G H I J K L M N O P Q R S T U V W X Y Z) do (
%comspec% /c if exist %%d:\ (
fsutil fsinfo drivetype %%d:|find "CD-ROM Drive">nul
if !errorlevel! EQU 0 set cdletter=%%d
)
)
echo CD-ROM found on drive %cdletter%:
endlocal & goto :EOF
An example of the output:
C:\_D\TEST>cmdfaq
CD-ROM found on drive Z:
Another related question. What is the file system of e.g. the C:
drive? As an aside note the possibility of spanning the FOR command
over several lines.
@echo off & setlocal enableextensions
for /f "tokens=5" %%a in (
'fsutil fsinfo volumeinfo
C:\^|
findstr "File System Name"') do (
echo %%a)
endlocal & goto :EOF
An example of the output:
C:\_D\TEST>cmdfaq
NTFS
Revisit
item #53
for testing whether the drive is ready or not, and for listing the
devices that are ready.
