the FW update tool on the sandisk site is for the iXpand USB 2.0 product. It has a picture of the product in the tool. This is not for the iXpand USB 3.0 product. If you ahve iXpand USB 3.0 SDIX30-XXX there is no FW tool for the product.
There are also two apps. iXpand Sync is used with the iXpand USB 2.0 and iXpand drive is for the iXpand USB 3.0. Make sure you are using the correct app and if so start another thread so we can get more info and troubleshoot.
