Oh Ed, if only we were all know it alls like you.
I have two of those SanDisk drives and also have not even attempted to get a lanyard through that hole. The last picture I see in this thread is not the same drive. The hole pictured is considerably larger.
I thought about it for a minute and think if I was going to do it I would try using a lanyard like the one pictured and thread it through the hole like you would thread a needle … with one of those helpers. Let me know if it works.
