batch script to find drive letter of a mounted device
提问by Without Me It Just Aweso
I am trying to write a batch script to locate a particular mounted device. I'm in windows 7.
我正在尝试编写一个批处理脚本来定位特定安装的设备。我在 Windows 7 中。
I know that the device will have the folder drive:\custom so I'm wanting to look at all possabilities to find a device with this path
我知道该设备将具有文件夹 drive:\custom 所以我想查看所有可能性以找到具有此路径的设备
Here is what i have so far
这是我到目前为止所拥有的
@echo off
setLocal 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 (
if exist %%d:\custom (
ECHO Device Found : %%d
)
)
This doesnt work though, it thinks it exists for every drive letter.. so i see 'Device Found' for every single drive letter. Why is that? Am I going about this wrong? How can I locate the drive letter that has a folder 'custom' on the root directory?
但这不起作用，它认为它存在于每个驱动器号..所以我看到每个驱动器号的“设备找到”。这是为什么？我这样做是错误的吗？如何在根目录中找到包含“custom”文件夹的驱动器号？
thanks,
Stephanie
谢谢，

Add \at the end of the path:
\在路径末尾添加：
IF EXIST %%d:\custom\ (...)

Use fsutil fsinfo drivesinside the forstatement instead of a static list of drive letters.
fsutil fsinfo drives在for语句中使用而不是驱动器号的静态列表。
for /f "tokens=1,*" %%i in ('fsutil fsinfo drives') do (
:: work with %%j here
)
However, if a drive letter is given to a device with no media, it maystill give an error. Either way, a check such as:
但是，如果为没有媒体的设备提供驱动器号，它仍可能会出现错误。无论哪种方式，检查，如：
if not exist O:\ @echo test
worked perfectly fine for me (with and without not). The drive does not exist on my system, so no output was given when the notgot removed.
对我来说工作得很好（有和没有not）。该驱动器在我的系统上不存在，因此not在移除该驱动器时没有给出任何输出。

A bit complicated, but this is the only solution to avoid blocking errors on Win7:
有点复杂，但这是在 Win7 上避免阻塞错误的唯一解决方案：
for /f "tokens=3" %%d in ('echo LIST Volume ^| DISKPART ^| findstr "Healthy Unusable"') do (
if exist %%d:\custom echo Device found
)
Another method i've found is using the volcommand + checking ERRORLEVEL(if == 1 the drive is not mounted):
我发现的另一种方法是使用vol命令 + 检查ERRORLEVEL（如果 == 1 驱动器未安装）：
for /f "tokens=3" %%d in ('echo LIST Volume ^| DISKPART ^| findstr "Healthy Unusable"') do (
vol %%d:
if !ERRORLEVEL!==0 if exist %%d:\custom echo Device found
)
NOTE: on WinXP DISKPARTwon't see removable drives...
注意：在 WinXPDISKPART上看不到可移动驱动器...

This works for a hard disk and a pendrive:
这适用于硬盘和随身碟：
@echo off
for %%? 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 (
dir %%?:\ > nul 2>nul
if exist %%?:\custom echo Device found(s): %%?:\
)
P.S.: Run WinXP
PS：运行WinXP
