Make a small program to do Ghost backup and restore under Win, which needs to detect the number of partitions in the hard disk (when a USB flash drive is inserted, it does not affect the detection result), so that the backup file can be automatically stored in the last partition. I know it can be done with Ghost32.exe, but I think it should be simpler to do it with batch processing. How to do it?

@echo off
set num=
for %%i 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 (
fsutil fsinfo drivetype %%i: | find /i "Fixed" >nul 2>nul && set /a num+=1
)
echo There are %num% local disk partitions.
pause>nul

Try this
@echo off
setlocal enabledelayedexpansion
for /f "skip=1 tokens=1,2 delims=\" %%a in ('fsutil fsinfo drives^|find /v ""') do (
set aa=%%a
set aa=!aa:~-2!
for /f "tokens=1 " %%i in ('fsutil fsinfo drivetype !aa! ^|find "Fixed"') do @echo %%i
)
pause

The method of htysm is okay, but after inserting the USB flash drive, an extra partition is detected. How to solve this?

The method of qingfushuan is to obtain the drive letters of each partition, but it also lists the USB flash drive. Also, is there a way to solve this?

Old Ge's stuff!
Hehe

There is a drvtypes that will display all existing drive letters and related information. Batch processing can judge the information and exclude USB drives A, B, RAM disks, and various optical drive disks.

The code on the 2nd floor won't display the USB flash drive. Unless it's a mobile hard drive.

『13th floor』:

Can the following be tried?

@echo off
setlocal enabledelayedexpansion
for /f "skip=1 tokens=1,2 delims=\" %%a in ('fsutil fsinfo drives^|find /v ""') do (
set aa=%%a
set aa=!aa:~-2!
for /f "tokens=1 " %%i in ('fsutil fsinfo drivetype !aa! ^|findstr /i "fixed removable"') do @echo %%i
)
pause

wmic logicaldisk where(drivetype='3') get caption

The method on floor 13 has been tried, but it still doesn't work. My USB flash drive is regarded as a mobile hard disk.
