Samsung T5 not showing up in update software on MacOS Catalina in Monitors and Memory 3 weeks ago 'No Samsung Portable SSD is Connected' in Monitors and Memory 4 weeks ago; Samsung Portable SSD T5 can not run macOS Catalina in Monitors and Memory; UR59C Curved 4K and MacOS Catalina 10.15.4 in Monitors and Memory. Exact same issue here. Waking from sleep and the SSD software attempts to find the drive again, spins in circles and wont find it. Unplugging it and plugging in again leads to MacOS crashing and requiring a reboot. Mojave 10.14.6. SSD Software 1.6.2 (1.6.6 caused issues with my mac) Macbook Pro 15 inch Mid 2015.
A hard drive doesn't need any software. If it is so flakey that it needs software, you should return it for something that isn't such a pile of crap.
Besides the activation software, it has also installed Paragon so that you can leave the drive formatted for Windows.
Unless you need it to work with Windows, that bundled NTFS software will likely break at various OS updates and upgrades because it is also a cheap, hobbled version of the retail software.
If you must use it with Windows and you must use their password scheme, you'll have to wait for Samsung to release a version that isn't garbage. No guarantee that won't break at the next update.
Or, you can format it for the Mac as APFS or HFS+ with encryption. Then get rid of the crapware they misled you into installing.
