Extreme Pro connecting to Linksys for FTP

Just purchased the 500GB to replace the usb hard drive I use for network folder storage

The first time I plugged it in setup worked fine for a couple hours,  it stopped working after trasnferring a large file

I was able to reconnect and use again for a short while again.

The drive does work on my regular computer but my Microsoft surface is getting insufficient power message for the usb which seems better after an update of usb drivers

So my question is do you think the Linksys cant handle the extra power demand?

and is there a part that I could provide extrernal power for the SanDisk?

I would really love to get this drive working

Working now after using external power through a USB hub.
