looks like they finally have a bootable USB image.)

Dear David, hi guys/girls that are following this problem.

First, the delay in my response is due to the fact that I'm fighting a lot
of parallel battles here, but I'm still trying to solve this problem.
In the next days I'll always try to reply.

I've done the bootable seagate HD test. It came up 100% ok, all tests. The
HD is new, I wouldn't expect different, but it is always reassuring to do
the real test and see the results.

To recap, I used the computer all day, since morning until late night. From
time to time, say, about 3 times that day, I noticed a small 5 seconds long
freeze. Sometimes, in other days, KDE wouldn't open plasmashell, but I did
not need to reboot; just open tty1, and run systemctl restart sddm, and it
would run ok. Not sure if this is related.

That night, I turned off the computer, no errors, nothing.

Next morning, first boot, it booted fast and I was faced with an empty
desktop. Also empty /home. After e2fsck, all my files reappeared as inode
numbers in lost+found. I was able to recover some of them, and I have
backup for others. But I'm not still putting them on the hard disk.

I'm still waiting for possible causes or solutions, or just to know what
have happened in the first place.

Is the "swap" partition something that could cause that if turned off by
"swapoff"? Because I remember turning it off during that afternoon. But I
used the computer a LOT until night, so, I don't think there was any link
to the disappearance of ALL files. Also, when I used swapoff, it was almost
without use anyway.

I read above from Abdullah, that it is very unlike to have such major FS
fail, and it looks like it didn't "flush" the night I turned off. This is
also my guess, it is the only thing that make sense. Maybe the inode table
was in the memory and got corrupted. But it is strange to figure that,
since the filesystem is EXT4, and it is very stable nowadays.

Someonelse asked if 2TB is ok for this laptop, Causey I believe, my inbox
got deleted, but yes, this configuration accepts a 2TB; also, this would be
a problem during the installation 3 months ago, and the consequences would
be far different from the reported problem here.

Thanks all for inputs and lets reason what else. I may be able to create a
virtualbox to test some theories in the future, to get to the bottom of it.
The laptop is still in guarantee period, I need to know if there is
something really wrong or if it was just an occasional, yet rare, event.

My best,

Beco


PS. Sorry for not copying Abdullah and Causey on the reply, my inbox got
cleaned here.

If Seagate Seatools is happy with the 2 TB drive, that should eliminate the 2 TB drive, the cable, and the motherboard port as sources of the problem.


Just to be thorough, you should also check memory. I've been using memtest86+ for years, but other people say there a better choices. STFW, pick one you like, download it, and run it.


STFW "lenovo ideapad 320", I see that there are many variants of that model. However, I am unable to find technical specifications or a service manual. Please post a description of the machine, the specific Lenovo part number/ whatever, and a URL to the exact same computer (if available). If you have a URL for technical specifications and/or service manual, please post those.


Please run the following commands as root and post your complete console session (prompts, commands, and output):

# cat /etc/debian_version

# uname -a

# parted --list

# mount

# swapon

# df

# cat /etc/apt/sources.list

# ls /etc/apt/sources.list.d/

# cat /etc/apt/sources.list.d/*


Have you installed any software using means other than the Debian built-in package management tools? E.g. download a source tarball, build it, install it; download a *.deb package and install it; etc.?


Have you changed, recompiled, or otherwise messed with the kernel?
