Thanks Arno,
If I have good understood, you think I can throw the HDD ? This command
cryptsetup -y -v luksFormat /dev/sdb
Simply destroys the drive ?
(I didn't ask any other operations on the sdb).
Regards,
Amel

Hi Amel,
I would say your disk died while you were doing the overwrite.
That is assuming nothing the OS uses was on sdb.
There is no logout-timer in ssh and anyways, it would not freeze.
Regards,
Arno

Hi everybody,
I did something wrong, can please someone help me ? I followed these
instructions to encrypt a internal HDD :
https://www.cyberciti.biz/hardware/howto-linux-hard-disk-encryption-with-luks-cryptsetup-command/
Unfortunately I did
cryptsetup -y -v luksFormat /dev/sdb
and not
cryptsetup -y -v luksFormat /dev/sdb1
After that I used fdisk to create sdb1 and did
cryptsetup -y -v luksFormat /dev/sdb1
cryptsetup luksOpen /dev/sdb1 prod
and
pv -tpreb /dev/zero | dd of=/dev/mapper/prod bs=128M
all this I did through ssh
but :
1. After a time my shell was frozen. Perhaps has ssh a timer ?
2. My HDD did repetitive noises several hours (now that has stopped), even
after a reboot.
So, my question please : have I to do something to erase what I did with
cryptsetup -y -v luksFormat /dev/sdb
And what is it ?
Have I to do something more, or were the noises of the HDD simple my
pv -tpreb /dev/zero | dd of=/dev/mapper/prod bs=128M
command, even if
ps -a | grep dd
didn't display anything ?
Thanks, best regards,
Amel :)
