Need a dos script to ignore the "There is no disk in drive.." error

Hello all,

I am trying to run a batch that will scan all drives to look for a folder, this issue I'm having is as soon as it his an empty DVD drive I would get the "There is no disk in drive" pop up. I need to be able to ignore this error and continue to scan, I am running this on Windows 7 64 bit.

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:\thisisatestfolderdonotremove

NOTE: I have seen one other posting about this issue but the fix did not work. Also I would need this in a DOS command, not vb script.

You could probably leverage WMIC to get only the attached physical logical drives. The command below should get you the disks in the server.

wmic logicaldisk where drivetype="3" get caption

xxdcmast,

Thank you, but that will not work because I still need to search through all the USB drives and devices for that folder, the purpose is to save a backup onto the drive that folder exists.

Did you try:

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 (
dir /s %%d:\thisisatestfolderdonotremove

so it would be something like:

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 dir /s %%d:\thisisatestfolderdonotremove

Not sure exactly what logic you want to occur when you do or don't find the file, but see if this gives you some ideas.
@echo off
for /F "skip=2 tokens=2 delims=," %%A in ('wmic logicaldisk where drivetype^=3 get deviceid^,volumename /format:csv') do (
  echo Checking:[%%A]
  if exist "%%A\thisisatestfolderdonotremove" (
    echo TRUE
  ) else (
    echo FALSE
  )
)

Your approach is almost right however, you need to add '\*' at the end like this:
@echo off
for %%d in (c d e f g h i j k l m n o p q r s t u v w z y z) do (
  if exist %%d:\thisisatestfolderdonotremove\* (
    rem
    rem Your code goes here...
    rem
  )
)

Open in new window

Another thing you can do is build a 'drives' string variable which you can use later. So, if you were to have say, drives C: D: E: and H: then your variable drives will be set to 'C D E H', like this:
@echo off
setlocal enabledelayedexpansion

set "drives="

for %%d in (c d e f g h i j k l m n o p q r s t u v w z y z) do (
  if exist %%d:\* set "drives=!drives! %%d"
)

Open in new window

Now you can search for your folder like this:
for %%d in (%drives%) do (
  if exist "%%d:\thisisatestfolderdonotremove\*" (
    rem
    rem Your code goes here...
    rem
  )
)

Open in new window

Notice the double-quotes around '%%d:\thisisatestfolderdonotremove\*'. This is required if there are spaces in the foldername.

If you decide to use WMIC then the following will work correctly.
@echo off

for /f %%a in ('wmic logicaldisk where drivetype^=3 get deviceid ^| find ":"') do (
  if exist "%%a\thisisatestfolderdonotremove\*" (
    echo %%a
  )
)

Open in new window

NOTE: When using WMIC, both 'deviceid' and 'caption' work equally well on my XP setup.

When testing code, be sure to remember it must distinguish between a folder named 'thisisatestfolderdonotremove' and a file named 'thisisatestfolderdonotremove'. All my solutions above are able to distinguish the difference.

Could you close this differently please?  It's not clear what solution worked for you, so rather than accept the comment as the solution, please select the post(s) that actually contain the code that worked for you.

I can't see how 37835242 could have resolved the problem, since at it's core it does basically the same thing your original example posted does, and should therefore throw the same error.

If on the other hand it was 37835334 that solved your problem, then it feels like post 37829718 should have gotten some recognition as well, since it is basically the same core approach with small adjustments.
