I've got a new USB SSD drive, A-Data SC685. Works OOTB on mac and windows 10. Windows laptop has dual-boot with ubuntu 18.04 and it doesn't work there.

dmesg output:

What's going on? Any ideas how to fix this w/o upgrading ubuntu?

Have you used it in any Windows with the default Fast Startup feature enabled? If so then you probably need to boot Windows with that drive connected, disable Fast Startup and shutdown.

No, just formatted it on Mac

What file system have you formatted it with? Typical ones of MacOS have no native support and MacOS has no native support for EXT or NTFS so... I think you get the picture

lsblk shows it as 0 size, it's not an FS issue. I tried with exfat and fat, I'd try ext4 if it was only possible to get block device working. To be clear – I can't even DD to /dev/sda

We still don't know what file system that is...

exfat. There’s one more fact that’s as important as file system on a block device that’s not properly recognized/initiated: ssd color. It’s white.

Ubuntu 18.04 had no support for exFAT therefore requiring the installation of exfat-fuse and exfat-utils

Now now, don't be rude @hryamzik - if you're getting frustrated, take a break, and go take a walk for a bit. (Comments are locked for an hour to let things cool down)

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
