No problem updating sx900
using my 128g SanDisk USB drive..
Hope yours isn't defective.. Good luck
Hi Donny,
Now that is weird.
Yamaha has a compatibility list , nothing over 32 gig.
I had a Sandisk ultra fit 128 gig, must have been the S950 I tried it in, wouldn’t recognise it, just tried it in the SX, it formatted , and appears to save styles.
So thank you, not that I’d probably ever use that amount of data on sx, but, better than having it sitting in a draw.
