hello,everyone
i met a big trouble
because my disk space in linux is full,i divide a windows' disk (E:\) into two partitions.
one is /dev/hda7 ,another is /dev/hda8
when i exec `mkfs.ext2 /dev/hda7`,i use this wrong cmd
`mkfs.ext2 /dev/hda6`,and /dev/hda6 is a exist ext3 partition already mounted on /home where my improtant data and personal files live on;
So,i was very worry,and use this `tune2fs -j /dev/hda6` to change /dev/hda6 's fs to ext3 and hope to get my lost data back;
but it's not work;
i'm sure data is there ,for after i lost /dev/hda6 ,i don't write anything into in;
so data is surely there;but os cant kown;

now i am very very panic ;i want my data back;
can anybody help me?
thanks for your help

If you truly ran a mkfs command on your /home directory and unless you have recent backups, I'm afraid it's gone. You could try taking it to a forensic expert but that can cost some money.
