System.IO.IOException: The device is not ready

I have an ASP .NET application that is copying two files to a new location.
All users work perfect except for only two that are getting the following error:

Exception of type 'System.Web.HttpUnhandledException' was thrown.: System.Web.HttpUnhandledException: Exception of type 'System.Web.HttpUnhandledException' was thrown. ---> System.IO.IOException: The device is not ready. at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath) at System.IO.File.InternalCopy(String sourceFileName, String destFileName, Boolean overwrite) at System.IO.FileInfo.CopyTo(String destFileName, Boolean overwrite)

See code below.

Thanks,
Dim aPath As New IO.FileInfo(strArtPath)
        Dim aWork As New IO.FileInfo(strArtWork)
        aPath.CopyTo("\\prodart\markport\" & newarchiveID & aPath.Extension, True)
        aWork.CopyTo("\\prodart\markport\" & newarchiveID & aWork.Extension, True)

Open in new window

Check if the user has permission for write at the location.

Thanks puru1981:
All my users have full access/rights to the server.
I am also using identity impersonate in my webconfig (using the administrator credentials)
<identity impersonate="true" userName="server\administrator" password="administratorpassword"/>

One thing more are you closing the aPath and aWork files. this error occurs when the file is in use.

ok.. so that is probably what's happening but I can't find an atribute/member to close the file.

These don't work with IO.Systemfile

aWork.close()
aWork.dispose()

Or should I do something like this?

 Using workfs As IO.FileStream = aWork.Open(IO.FileMode.Open, IO.FileAccess.Write, IO.FileShare.ReadWrite)
            aWork.CopyTo("\\prodart\markport\" & newarchiveID & aWorkExtension, True)
 End Using

But not sure if it will work...

Thanks a lot for helping me out.

using is used only with classes which use IDisposable interface.

i think there is some other issue is preventing to copy the file. can you do one thing add same random string at the end of the file and then check if it still happens.

I am afraid I can't since these are all art files (jpg, ia, png, etc)  :(

I think this is due to this

newarchiveID

once this is generated it is not allowing other threads to create the same.

so you need to be aware if the same archive id is used by all the users if first user is writing the file no other user can access it so you are getting the error.

Good thinking but I don't think that is the problem. Let me explain the newarchiveID  a little bit more.

An user works in two versions of the same file
aPath is the path to the art file which is always a JPG
aWork is the path to the work file wich is an editable version of the JPG (illustrator, photoshop, etc).

When they finish working on the files they are requiered to copy both files to our art server.

When they do this, the system creates a unique id for each file  (newarchiveID) and copies both files to the art server, both with the same name (newarchiveID ) but they keep their extensions so we know what type of files are they.

So, the newarchiveID  is a unique consecutive number generated by the system to idenfity the set of files but it is totally different between users, so, there are not going to be two users using the same newarchiveID .

I do think that you are correct and the issue has to do with the fact that the file is not being closed, after copied.
