Error while 2D classification:Encountered OS error while caching: [Errno 22] Invalid argument:

Hi,
I’m getting this error while trying to run a 2D classification job. Although not best practice, my cache and database are currently stored on the same external hard drive. I was wondering if the issue is due to the file system of the external drive? Is there a way of solving this without having to change the file system of the drive?

Thanks,
Yakup
