e2fsck -y wipe all my data

[Yordanis Tornes Medina]

Hi

I have a HD connected as USB device and cause for electrical problems in my home, my disk
go off unexpectedly more than one time some weeks ago, a few days ago I can't mount
neither of my linux partitions on that disk.

Always I get this error: org.freedesktop.DeviceKit.Disks.Error.Failed: Error mounting:
mount exited with exit code 32: mount: Stale NFS file handle

I run an e2fsck -y /dev/sdb6 (one of the partition) and after the command finished I mount
the partition and... the partition is like a new linux partition, all my data is lost.
Under Nautilus/Properties filesystem type is shown as ext3/ext4 and under Gparted
filesystem is shown as ext2.

Any idea why is this? Or how can I restore all the data pre existing in that partition?

Greetings

I have been away on leave but I thought I would comment.

If you have electrical problems, get a UPS.  Also, check the drive the 
next time you plug it in.

You may have to run some forensic's type software (Foremost) to recover 
your files.

  I had an issue where my fingers deleted (Slap fingers again and again) 
  a whole partition of data.  I did recover about 20% of the data which 
was better than I expected.  The partition was part of a RAID and LVM 
array and I only had one of the two drives from the LVM.

If you haven't, don't use the drive yet.

Also, there are some ways to undelete ext2 files but it isn't from what 
I have heard.

Good luck.

One assumes that the partion's structure was really screwed up and e2fsck removed the
pointers to your data.

OK, I read man page for e2fsck before run the check command, I understand that -y option
is telling yes for any question of e2fsck command, but, the man page said that e2fsck is
used to check a Linux second extended file system (ext2fs), I yet don't understand why
all my data is lost. But, really is not in my disc.

You also need to know that in the root dir of the partition
that got wiped out, you will find a directory called lost+found,
where ALL of your lost files are saved, albeit, not in a form you
can use nor make any sense out of.

If that dir is empty, well, or it does not exist, then I believe
the stuff is pretty much gone.

BUT (always a but), look at those links I sent. There is some
software that can help you if you know what you are doing.

Cheers,

JD

in addition to link jd posted, from a terminal, run 'man e2fsck'.

press '/' and type in '-y', press <enter>, press 'n' key
twice to see
what you did.

after, read entire man for e2fsck to have a better understanding of how
it works.

before you run any command that you are not sure of, use 'man' to read
up on operation.

it has been said many times, 'man is your friend', and it can save you
a lot of problems by knowing how commands work.
