Cannot detect external hard disk drive

I have a few hard disk drives I use to make backups (they are in ext4 format and encrypted with LUKS). I have been using them regularly recently (two days ago) but now after two updates I am apparently not able even to find them with fdisk -l. There is no response of any kind I can see when I connect these disks.

All I have been able to deduce is that its probably something with the OS. Disk are not recognized in any USB port, and they are correctly detected in other laptop I got with a different Linux distro.

Any pointers to a solution are appreciated. Thanks.

update with the output of `lsusb`. It does not change with the disco connected or not.

Have you an older/previous kernel if so boot him up for test please.

Apparently, the latest update just fixed it alone. Answering the above anyway, I had not a different kernel available to boot from.

And wrong again. This is annoying...

Just figured out the kernel thing. I have in fact several versions, latest is `5.11.0-46-generic`. Booted from the previous one on backup (`5.11.0-44-generic`) and after reboot it detected the disk correctly. But after another reboot (without updates), it won't again. This is really, really weird.

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.
