PC cannot detect Nano Memory

[shaunydub]

Hi.
I couldn't find a specific Nano thread with issues so post it here as I am using with my P30P.

I got a Nano memory card + official Huawei USB reader so I could transfer my music and other things before my phone arrived.
When I connect the reader the laptop is detected and shows 2 drives - nano mem and standard sd - however my laptop just does not detect the nano memory when it is in the reader.
The drive letter stays greyed out.

I do not find anything online about this specific issue, I wondered if I would need to format it in my phone first but that doesn't make a difference.
Anyone have issues?

(in the end I copied my files laptop>usb stick>phone USB C connector > file manager to copy and paste but it was an extra step I could do without).

Try looking at the card in disk management in admin tools

Yup, I tried this but no luck.
It's odd, the usb stick works with normal SD, the nano works in my phone fine but doesn't get detected in the stick.
I can't try in another laptop as my work one has USB drives blocked

Wonder if the nano card uses an unknown file format. Will probably need to be formatted in the phone. When my note 4 originally came out, that's what I had to do.

Yeah I wondered this too, I'll try it again and see if it picks it up.
Will also try my old Teclast dual boot tablet and if it can detect in windows via USB OTG to the reader.
