I created /etc/modprobe.d/nf, rebuilt initramfs and rebooted the system as you said. I highly recommend you do NOT mount the EXT4 partition nor unlock the drive (via the KDE applet) even if it looks like it’s working.īecause of what happened during the Manjaro update process, I advise you only unlock the device temporarily, force a fsck, lock the device again, unplug it, and then you should be good to go. Reboot, plug in the USB drive, and see if it works, or if there’s any additional behaviour. conf file for safe-keeping if you ever need to use it again (and assuming this will work!)Ĭp -v /etc/modprobe.d/nf ~/ conf files.įor safe measure, exit out of the root user’s shell with CTRL + D, then rebuild your initramfs:įinally, make a backup of this custom.

Have your USB unplugged during this entire process…įirst elevate yourself to “root”, as sudo won’t work for this step: Okay, try disabling UAS for that drive and rebooting. After ejection, update completed immediately and I rebooted the system. One or more file on this device are opened … Before ejection, I pushed safely remove button but it said : I tried to close Dolphin but it didn’t close normally(it got into not responding mode), so I tried to close it by sending kill signal, it didn’t work either. Note: While updating, Dolphin file explorer was opened on the hard drive. Right now I don’t think, no system can detect the hard drive as a connected device. I’ve tried to connect it to Ubuntu 20.04 and windows 10, unfortunately they can’t detect the hard drive too. When it’s connected, nothing happens but engaging CPU. System works correctly for the NTFS one but for the other drive, it’s quite other way around. One with NTFS format and the other one with ext4 LUKS-encrypted. Two hard drives were connected during the update. It’s close enough that’d probably be rejected for plagiarism by the auditing software used for school work.After recent update, my system can’t detect one of my external hard drives. However, users can “Unintentionally” initiate the install process and delete their hard drive contents in most cases.” “Booting a persistent Live USB gives the users access to the “Install Ubuntu” icon on their PCs desktop. Students can “accidentally” start the install process and delete the contents of the hard drive.” “Booting a persistent Live USB gives the students access to the “Install Ubuntu” icon on the desktop. Most of this guide is lightly paraphrased (confusingly so in some instances with that typo) from the top answer in this askubuntu thread from 2013 – “What would be the differences between a persistent USB Live Session and a installed Ubuntu in a USB drive?” “Emmanuel” doesn’t deserve a lot of the credit that’s given here. Third, Persistent Live USB is more secure.Īfter so many contradictions I was too tired of reading more. Third, Persistent Live USB is less secure. So, generally, you will require a USB drive of around 8GB or more to carry out the process without struggle. When it comes to installing Full Linux on USB, the installation takes more space than keeping the image of the installation DVD, which is approximately 5GB. However, when creating a persistent Live USB, you need a slightly higher one, say 4GB. This is because someone can create a non-persistent Live USB with a 2GB USB drive. Conversely, if the installation is done on a PC that lacks any proprietary drivers, that typical installation may fail on the machines that need them. Once these drivers are installed, the USB may not function on PCs that lack that specific hardware. The USB stick will make the OS portable and, of course, allow kernel updates which the Persistent Live USB does not support. On the other hand, a complete Linux install on USB refers to a standard installation of the OS, specifically Linux in our case on a USB drive.
