Hello,
I was trying to install FreeBSD 5.2 in the slice ad0s3 but
accidentally I wiped two partitions of my 4.9 system which
were in the ad0s2 slice :(
ad0s1 -> Linux boot
ad0s2 -> FreeBSD 4.9 (deleted partitions)
ad0s3 -> FreeBSD 5.2
ad0s4 -> Extended partition
they were the root and var partitions (usr and home were
in different disks).
strings /dev/ad2s2c | grep "/dev/ad0s2.*ufs"
/dev/ad0s2e /var ufs rw,noatime,nosuid 0 1
/dev/ad0s2a / ufs rw 1 1
As the disk hasn't been reformatted or written over all the
data is still here.
I haven't got luck googling, so I would like to ask for
advises. Perhaps searching some type of signature helps
to find the deleted partitions.
thanks you.
