获取磁盘的数量、所有磁盘的大小

@echo off & setlocal enabledelayedexpansion

set disk_count=0
for /f "tokens=2" %%i in ('wmic path win32_diskdrive get deviceid^,size^| findstr ^^[0-9] ^|sort') do (
 set disk!disk_count!_size=%%i
 set/a disk_count+=1
)

echo 磁盘数量：%disk_count%
for /l %%i in (0, 1, %disk_count%) do if %%i lss %disk_count% (echo 磁盘%%i大小：!disk%%i_size!)
