[Trisquel-users] Re : deleted ext4 partition

[lcerf]

You overwrote with zeros ("if=/dev/zero") the beginning of /dev/sda1  
("of=/dev/sda1"), 2048 blocks ("count=2048") of size 1k ("bs=1k").  2 MB.   
Almost nothing!  There is much to be rescued if you want to: the other  
partitions are intact and a program like PhotoRec can recover almost all  
files on /dev/sda1: http://www.cgsecurity.org/wiki/PhotoRec

But does /dev/sda1 even contain user data?  It makes no sense recovering  
system files: reinstall.  Now if /dev/sda1 only contains user data, there is  
nothing to reinstall: the system is intact.
