creating a folder on a new drive?

[Peter Sanders]

Folks

I start off with a blank volume on win2000 (not mounted and not
formatted). I mount a drive letter onto this volume by delegating to
microsoft diskpart, then, format the volume (NTFS) by delegating to
dos format command. Both diskpart and format command then exit. I
now want to create an empty folder on the newly created drive.
Whichever way I try to do this (by java.io.File mkdirs, or by
delegating to dos mkdir command, or by C calls to windows operating
system), I get the same error message : "The parameter is incorrect".

Has anyone got any ideas why I can't create an empty folder on the
newly created drive, or any suggestions how to do it?

Thanks in advance

Have you tried "md" by yourself? (To make sure you can create an empty
folder on that drive)

Hi Song,

Yes, we've tried that and it does work (ie it does create the folder).

If in one run of the code I simply mount and format the drive and then
in another separate run of the code I try to create the folder on the
new drive, this works, the folder is created.

However, if I try to do it all in one run of the code (i.e. mount,
format and create folder) the folder creation fails. It seems that
java isn't fully aware of the newly created drive...

Once the drive has been mounted and formatted, doing:
Arrays.asList(File.listRoots());
gives a list of all drives: C:, D: and Q: (new drive letter is Q).
but then the following conditions are met:
(new File("Q:").exists() == false)
and
(new File("Q:\").exists() == false)
i.e. the File.listRoots() function is aware of the new drive
but the File.exists() function is not aware of the new drive...
Then however I try to create the folder, folder creation fails.

Help...

Thanks in advance
