I followed this thread, and couldn’t remember ever having the same issue.
But today I was bitten: It’s a 3 TB external USB drive from Intenso.

Yesterday I was in the middle of a backup (it’s my main backup drive), but I
had to sleep and so sent the machine into standby. I had to start the PC
again a few minutes later in order to unmount an sshfs of it on another
machine, and sent it right back to sleep.

Just now I switched the PC back on and the drive was gone and off (USB
enclosures tend to spin down the drive when USB disconnects). So I pulled
the USB cable and plugged it back in for the drive to start and be
rediscovered. That worked and I resumed the backup, but this enclosure has
the nasty habit of sometimes intermittently disconnecting on its own.

Its device was not gone (it usually disconnects for a tiny moment and then
comes back, probably a USB issue), so I just tried to open it again in
Dolphin, which gave me:
Error unlocking /dev/sdd1: Failed to activate device: File exists

$ blkid | grep luks
/dev/mapper/luks-6a55a712-773e-4cd8-9776-fc9b6f39a998: LABEL="backup" UUID="50ed9519-cd9c-4d11-b78a-9f057b089362" BLOCK_SIZE="4096" TYPE="ext4"

$ cryptsetup luksClose luks-6a55a712-773e-4cd8-9776-fc9b6f39a998
Device luks-6a55a712-773e-4cd8-9776-fc9b6f39a998 is still in use.

I don’t quite like this bad habit of the enclosure, but a 3 TB drive is a 3
TB drive. I just looked at smart to see how old it is, because it has only
350 hours of power-on time, but it must be at least 5 years old. And
smartctl tells me there is a firmware update available! (for Windows, Mac
and—lo and behold—a bootable ISO, let’s hope it works with USB sticks).

Perhaps this fixes the issue. Dale, maybe you should look for the same.
