Drives: HDD Total Size: 515.5GB (2.3% used)
ID-1: USB /dev/sda model: Ultra size: 15.4GB
ID-2: USB /dev/sdb model: Elements_1042 size: 500.1GB
Partition: ID-1: / size: 11G used: 8.4G (84%) fs: ext4 dev: /dev/dm-0
ID-2: /boot size: 472M used: 68M (16%) fs: ext2 dev: /dev/sda1
ID-3: swap-1 size: 3.22GB used: 0.00GB (0%) fs: swap dev: /dev/dm-1
This is worth noting. So, / and swap-1 seems to belong to the external USB HDD, but it can be inferred that the size of the HDD is only (11 + 3.22) GB and not ~500.1 GB.
The /boot partition seems to belong to /dev/sda1 which is the 15.4 GB USB stick with Mint 18.3 installed.
Just to confirm with you, you now have 2 USB flash drives with an external USB HDD?
In the very first log that you posted early in the thread, that 7.6 GB device with an iso9660 file system is the Live USB stick which has Mint 19's installation files?
Is that correct?
If this is true, it makes me wonder why your 16.4 GB USB stick with Mint 18.3 installed only has a /boot partition and not other file systems such as /, /usr, /tmp etc. How can you Mint 18.3 work without all other files except from those in /boot? Or is it because the / and swap-1 partition (referred to as /dev/dm-0 and /dev/dm-1) belong to the Mint 18.3 system.
Do you use LVM on your Mint 18.3 system?
Yes, the 8GB one is the Live USB stick which has Linux Mint 19 installation files. It used to have 18.3, but after installing that 18.3 on the 16 GB USB stick, I formatted it and copied Mint 19's installation files.
Yes, again, I have 2 USB flash drives (18.3 installed and and 19 Live USB) and an external Hard Drive (500 GB).
I have no idea how it can run Linux Mint without the files you mentioned (which I thought the drive had them all) and I do not use LVM on this USB stick.
By the way, I have another Hard Drive (the 3rd one this is) which I thought was faulty due to the fact that Linux never managed to complete installation on this drive (after that I could not get it formatted). Just to check it again, and maybe to repair it, I ran the software "TestDisk". It's running for hours and but still only 30% is completed. The reason of me mentioning this Hard Drive is the result of this test (even thought it's not finished yet). It just seemed absurd to me; but, you, more experienced users will surely analyze it better.
(Smart Test Info for the same Hard Drive)
Now, I also checked the smart test information for the SATA drive I mentioned in the first message (the faulty one) and it turns out that it passes the test altough it possesses 720914 reallocated sectors. I do not have the slightest idea why this Drive does not work, but I am going to find it out.
Update: I just installed Linux again (by letting it take care of everything) and I still get the Read Error.
