Hello,
I have a couple of USB devices - a disk-on-key and mobile hard drive) - that were connected to an old and questionable PC, and now they don’t work as before. When connected to my PC, they aren’t recignized: the Disks & Devices notification doesn’t pop up and when opened it says “No removable devices attached”. lsusb Identifies them correctly and so does gparted (it lets me create partition table and add partitions), but lsblk doesn’t see them at all. What could be the problem?
TIA
Hello @ForeverNoob 
Sorry, but your interpretation of what you see is not enough, show us at least what you see.
lsusb -vt
sudo partprobe -s
lsblk --fs
Copy and paste it here as preformatted code. This forum supports markdown.
Hi and thanks for answering,

The unrecognized drive is /dev/sdc (Toshiba USB HDD)
Well, only usb storage I can see is this one:
and it must this one:
Sorry, but that device is there and reconized, but not mounted. Btw… exfatprogs and exfat-utils needs to be installed, to mount it.
hm… maybe try this to see what happens with the usb device:
Run this in a terminal:
sudo dmesg --follow-new
and re-plugin the usb device.
Share the output here.
exfatprogs is installed, exfat-utils is in conflict with the former. Other devices (USB-SATA SSD, different DOK) works OK.
This is the output of dmesg --follow-new for the Toshiba HDD:

Also, the Samsung DOK was tested on Windows too and seems to be working OK.
Thanks
Your DOK, commonly called a Flash Disk, is damaged. It has several read errors. Maybe Linux is a bit more strict about errors than windows.
Your Toshiba HDD is working normally.
OK, so why can’t the Toshiba drive be mounted normally like before?
No idea. Does it affect all usb drives?
Thunar, Nautilus, Dolphin etc. uses udisks2 to mount disks. Maybe there is something disabled?
It can be mounted also this way:
udisksctl mount -b /dev/sdc1
I was able to restore the Toshiba HDD by re-creating its partition table, seems to be OK. The flash drive still refuses to work and can’t be mounted. Its probably beyond repair.
Thanks for your help.
