Hello,
Here is my current thinking.
2 days ago, I received a brand new UBS key (Lexar S75).
I inserted it inside the UBS port of my Linux machine.
I open the key (it mounted automatically) and read the instructions
about the encryption coming with the key (by opening a file).
I did not pay too much attention because I was not interested,
I just changed the size of the
first partition and I added a ext4 partition.
Later I turned off the PC.
The following day, I tried to restart te computer, but I was
unable to boot.
Thus, I try to read the key from another computer and gparted did not
like (fdisk was giving wrong partitions). Thus, I had to entirely
repartition the stick.
Anyway, I started to investigate the issues with the PC which could
not boot. And I arrived at the point that the partition tables of the
3 HD were mess up.
Now, I am making the link.
Can this stick have a virus which may have mess up the partition tables.
Please, note that one of the HD probably still had a XP OS bootable.
I did not use it for a very long time.
What do you think?
My Best.
