Trouble hooking up 2 external HDs

I have 2 5 TB external hard drives (both My Passport Ultras), but when I try to hook up both at the same time, I get the following error:

Try another USB port or Cable
We see your external storage, but the connection is too weak to use. (0x8082000d)

I can install and transfer games just fine, but not play them. It appears the generic USB C cable I got from my local Walgreens is the problem, but I want to confirm that before going out to buy a hopefully better one from Best Buy.

Is my problem just a poor quality cable? How do I tell good quality cables from bad ones?

Probably the Cable.. Ive got 2 HDDs attached to an xbox-s (a 4TB HHD on one of the rear ports, and a 500Gb SDD on the front USB)

The initial SSD to USB connector for the SSD I was using, didnt let the xbox see it as fast enough.. a replacement adapter solved that.

so yeah. cable problems.... How to tell good quality from bad? buy a from a reputable location.

Thanks Msross. I'll head to Best Buy later today and get a new 1 ft USB-C cable and put the 3 foot one from Walgreens with my spares for recharging my phone.

Unfortunately, Best Buy didn't have any 1 foot cables. So I got a high quality 1 meter cable (I could have gotten a three pack of 3 foot cables for a few bucks cheaper, but I don't need that many and was told the brand I got (Belkin) I got was high quality).

Now I can play games from both my external hard drives!

Thanks again Msross.
