Review on High-Speed Titanium Micro Mercury 1TB External SSD | 1000MB/S NVMe USB 3.1 | IP66 Water/Dust Resistant | Portable for PC/Mac/Android/Gaming by George Johnson

I bought this disc to backup my Macbook. The first one was shipped and wouldn't mount, after speaking to Revain tech support and disconnecting until the issue was resolved I just sent it back. I'm fairly tech savvy and have other external hard drives that mount with no problem. After getting the second one, I wanted to mount, partition, and run the backup overnight. When I woke up, my laptop said the hard drive was unreadable and needed to be reformatted. Now it won't mount. One time it can be an anomaly, the second time it can be a pattern.
