Pop_OS won't detect an external SSD (lemmy.ml)

I plug in an external 1TB Crucial X8 portable SSD via USB but the OS can't detect it. I used to use the SSD as external storage for a PS4. I can plug it into my phone and a Chromebook and both detect the drive automatically. I've tried reformatting the drive via my phone and the Chromebook, I have connected it via 3 different USB ports, and tried another USB cable, all with no success.

What else can I try?

Does it detect the drive itself via an fdisk -l?

What does dmesg say?

fdisk -l does not detect the drive.

dmesg | less says:

Is this an older build of PopOS that perhaps doesn't have exfat compatibility in its kernel?

[-] [email protected] 2 points 1 week ago

No, I keep it updated

[-] [email protected] 4 points 1 week ago* (last edited 1 week ago)

are exfat-fuse or exfatprogs packages installed?

Can the popOS install format the USB? is it listed in lsusb?

[-] [email protected] 1 points 1 week ago

popOS cannot format the drive, at least, it cannot see it in Disks. lsusb shows the drive

Bus 001 Device 021: ID 0634:5600 Micron Technology, Inc. Crucial X8 SSD

Does lsblk list a block dev for it?

[-] [email protected] 1 points 1 week ago

Run dmesg -w or dmesg --follow, press control-L to clear the screen (all of that stuff is irrelevant), then plug in and unplug the drive a few times. If you get messages, then the kernel can recognize the drive. Press control-C when you're done.
