why my Ubuntu freezes or shows black screen when i either plug or unplug large external drive?

cn flag

I remember that I saw some thread before that has a similar question, but still, I need help.

When I boot up and my second external hard drive (could be either NTFS, exFAT, etc.) is already inserted before, everything works fine, until I unplug that said external hard drive. All icons vanish and replace with empty rectangles, and in a few moments later everything becomes unresponsive except my cursor and power/log button. When I reboot/shut down my PC, I get an error message.

Also, when I plug in my same second external hard drive on my computer after ubuntu completed booting up, my screen goes black and freezes. I had to hard reboot everything to fix this.

I have 2 external HDD: one is Toshiba 1 TB, where Ubuntu is installed on, and Seagate backup plus 4 TB, the drive that gives issue here.

I hope not it is a duplicate question, but still I need a help for this.

Then run the command posted by **T Br** - we can't help you if you don't provide information. I'm sure that the problem lies within your external Hard disk - but only the syslog will tell (dmesg would work as well)

the problem happens when i unplug the HDD when ubuntu is active. Also when I plug-in the HDD, ubuntu crashes short moment after. Perhaps it is connected with a USB bridge with another HDD, which is where my ubuntu is installed?

welp, i found the issue: I connected both the main HDD (the drive ubuntu is installed) and the second HDD on a USB Bridge connector which connect to my PC by usb-C

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.
