Error 1430 When Trying to Access Files in a Portable Device on Windows Through LabVIEW™

Issue Details

I am trying to programmatically acquire a list of files stored on a USB device using LabVIEW. The device appears under Windows as a Portable Device rather than a storage drive. When I specify the device path in LabVIEW, I receive the following error:

Error 1430 occurred at an unidentified location

Possible reason(s):

LabVIEW: (Hex 0x596) The path is empty or relative. You must use an absolute path.

Solution

LabVIEW can access files only through valid file system paths. Devices that appear in Windows as Portable Devices typically do not expose a traditional drive letter that LabVIEW can use as an absolute path.

To access files stored on the device:

1. Verify whether the device supports a mass-storage mode that allows Windows to recognize it as a standard storage drive.
2. Configure the device, if supported, to appear as a USB storage device instead of a Portable Device.
3. Confirm that Windows assigns a drive letter to the device.
4. Use the assigned drive letter when building file paths in LabVIEW.

If the device does not support mass-storage mode, Windows may not provide a file system path that LabVIEW can access directly. In this case, determine whether Windows can expose the device storage as a drive letter. If the device appears as a storage volume in Windows, assign a drive letter and use that path in LabVIEW.
