I have a 500GB USB disk that I regularly use with my laptop. It is Ubuntu 24.04
up-to-date.
This is a 500GB Seagate Expansion SSD external USB 3.0 disk.
Today I mounted it on my fedora 42 server and deleted some video files in
preparation for taking a backup of this disk.
This is probably not relevant. Checking the system log for the last year I see
that a similar (but shorter)
burst of errors often reported after I eject this disk.
I finally did
$ sudo umount /sata
$ sudo eject /dev/sdi1
Just then I got a flood of errors in the system log (see at the bottom).
[I later remembered that 'eject' already does a 'umount', but this made no
difference. Even if I mount the disk ro]
Whenever I mount, then eject the disk I get the same list of errors, different
tag numbers.
fsck had nothing to say.
I thought that maybe deleting those files left behind some delayed work that
did not complete, and the umount/eject did not wait for.
Then when mounted again it attempted to do this???
I also booted this disk on my laptop (as it is always used) and left it alone
for 15 minutes, then shutdown.
Mounting it on the server and ejecting it still gave the same errors.
I have no idea. Does anyone here?
TIA,

Tested on a laptop, running clonezilla (kernel 6.12.17-amd64) and I get these
errors too.
My f42 is running 6.17.8-200.fc42.x86_64.
In addition to the original disk, I found that I have another USB 3.0 SSD
(Toshiba X10) so I tested it:
$ sudo mount -o ro /dev/sdi1 /sata
nothing unusual in the log. Wait a short time, then:
$ sudo eject /sata
and immediately I see this in the log (see at the bottom).
This means that it is not a problem only with one specific disk, one specific
socket (tried a few), one machine or one kernel.
Anyone with ideas?
TIA
