You'd want to test the drive for errors, now, in case it was the cause
of the crash.  There's no point continuing to use a faulty drive, even
if it appears to work at the time.  There are tools that can be
downloaded from the hard drive manufacturer's websites to test their own
drives (either windows tools, or they make a bootable CD that bypasses
any OS on your computer).  And there are SMART tools that can be used in
Linux.

Unexpected severe crashes and drive corruptions can just be a random
glitch (such as a momentary power fail), or indicative of some hardware
fault in the computer (the power supply, the drive itself, RAM,
motherboard, et cetera).  Or, simply, that the cards plugged into the
motherboard are walking loose of their sockets, and pulling them out
then re-inserting them is required.  And the old favourite, of the CPU
cooler being gunked up with fluff so the CPU overheats.

I'd try to do some investigation into *why* it failed, if I were you.

What does it mean to "tree" lost+found?



"tree" is a command that shows the contents of any directory, its 
subdirectories, and any files they contain.  Very useful.

Did anything show up in the /lost+found directory?


1,100 folders

Good advice.

I had a box boot for the specified number of times to require an fsck. 
I ended up with a box that wouldn't boot.

Returned the drive to its original box and booted.  Came up without a hitch.

To this day I haven't the slightest idea what happened to corrupt the 
drive and can say that its the first time I've ever found anything in a 
lost+found directory.  Very glad it was there.


First time in 15 years I've seen anything like that.

Good for you.  Glad you achieved some lessons learned and success in getting 
some data back!
Now you can have a great weekend!

SOLVED: sda2 is corrupted

[Jim]

Will guys I want to thank all of you that help me on this project.

This computer crashed four days after I gave it to my friend ,he said he 
just exited from playing his Games to logging onto the internet with 
Firefox. and something popped up about robo.. and he could not 
restart computer.
It would come up to "rescue grub" at bootup, I checked the partitions 
with gparted it changed the  / an /home partitions to "UNKNOWN".  It 
crashed two partitions


I finally got the img of sda2 on to external hard drive 26gb.

Then I did a e2fsck /dev/sda2 it took e2fsck about 45 mins to fix the 
sda2 partition , One of Two users /home directories was totally gone , 
the one tjhat was being used at CRASH time.  But the one that was not 
being used and had the important data to be saved was still intact.


I have never seen a Linux computer crashed this bad.
