My Sandisk ssd extreme wont mount to my mac. Getting: error 49153 when I try to mount. All my software if up to date. I've tried multiple computers, ports, cables, sides of cables. Nothing works. Ran first aid and everything came back clean. Not sure what else to do.

I have two comments. First, how is it formatted? It should be formatted the same as your Mac's HD is. Second, reformat only with Apple's Disk Utility app. Do not use any maintenance app that came with the disk. They almost always cause problems. Did you use one of them? If so, that could be the cause.
