I received this message on telegram from a chinese reseller
Attention users of official Bitmain firmware! If you upgrade your s17 + / T17 + to the firmware from 2020-06-18. You can no longer use the SD card. Bitmain has accidentally or intentionally disabled this feature.
I don't know the initial source and I have not verified the matter personally but I trust grace who forwarded this message.
So far this only mentions the + versions, but I would be careful with all other 17 series until things are in the clear.
