KDE Disk and Devices App Crashed Entire System

More fun. For the last two days or so this situation has occurred. First, let me set up the environment.
I have an external powered USB hub with has four external SSDs attached to it. One holds my pictures (and porn), one hold some backups, the third holds different backups, and the fourth holds some other files. I turn these on in the morning when I get up, they stay on all day, as they’re used, then in the evening I click the “Remove Safely”, then turn them off.

For the last two days, at least one of the drives will not remove. I click “Remove Safely” and nothing happens. The disk appears to remain mounted. No amount of clicking changes that. I can open the disk with Dolphin and close it, and then click on “Safely Remove” and nothing happens.

Tonight I messed around doing the same thing, trying to get the drive to dismount. I can’t remember precisely what I did, but I think I opened the properties of the drive in Dolphin, and the instant I clicked on “Properties”, the entire system crashed like a rock. Black screen, no desktop, no nothing, dead as a door nail. I had to shut down and reboot. The system came back up fine. I turned three of the drives off before the system rebooted.

Has anyone seen anything remotely resembling this behavior? I have no idea how to approach this issue.

When you can’t unmount a drive this is most likely a sign that a read/write/buffer process isn’t finished and blocks the umount command…

I think you’re right. Some virtual machines get backed up to that drive. I had run those machines that day. I just now got the idea to check the log for the backup - and sure enough the backup failed during a long run. So I’m rerunning the backup.

Surprised I couldn’t figure that out myself. Thanks. Problem solved. Although it’s still pretty bad that KDE dropped the entire desktop… :slight_smile:
