Strange log message

The log shows the following:

print_req_error: I/O error, dev sdd, sector 6293504
июл 10 10:52:40 roman-pc kernel: print_req_error: I/O error, dev sdd, sector 6293504
июл 10 10:52:40 roman-pc kernel: Buffer I/O error on dev sdd1, logical block 786432, async page read

But I do not have a sdd1 device!

What's happening?

Have you tried using the forum search function?

This post might help you:

My question is not about an error, but about a device that is not in the system. As you can see, error on sdd1 that is not in the system.

Could still be worth trying a different kernel and if that does not help then provide more info so that one of the forum experts can assist you.

See:

I tried 4.14LTS and 4.19LTS.

Hi nrw!
Did you check the hard drive for errors?
Is the HDD firmware up to date?
In my case I had to upgrade the firmware to fix this error.
Hope it helps

If you have any partitions on /dev/sdd listed in /etc/fstab, then add noauto,nofail to the mount options for those partitions ─ no spaces after the commas ─ and make sure that the two numerical fields at the end of the line for each of those partitions are set to "0".

Which log! Post the used command.

Maybe a usb plugged in gave this error as usb is always the last entry
