The address of the error was at 0x7a0ba769, on thread 0x1294. The        error code is 0xc0000005. This error may be a bug in the CLR or in the unsafe         or non-verifiable portions of user code. Common sources of this bug include         user marshaling errors for COM-interop or PInvoke, which may corrupt the stack.

I’m not sure what that error means but if you want to get the drive’s size, you can use

        DriveInfo di = new DriveInfo('f');  //Put your mobile drive name         long totalBytes = di.TotalSize;         long freeBytes = di.TotalFreeSpace;
