The harddisk is just my slave harddisk for ftp files as I the main hd mounted
as /dev/sda2 /boot and /dev/sda4 /.
/dev/sda1 is made for dos use and /dev/sda3 as swap.

 AV>0. You've already lost all your data. Now, let's see what you can do...

Ok, so it it then more only try to make a new full 1tb with fdisk and partion
for ext4 as all files is lost on it.

I will see if I can do with this command as it allready now not is tied to be
mount and the system log file by startup showing errors on the harddisk by read
it only.

That will I then do then.

I try do do this then. I normally for ftp harddisks mount then as /dev/sdb1
/home/ftp.
