Post subject:  Filesystem check failed: Any tips on how to fix?
My box is down the computer gets stuck at 27% and I get a messages about Filesystem Check Failed:

Please repair manually and reboot. Note that the root file system is currently mounted readonly. To remount it read-write type: mount -n -o remount ,rw /

and a prompt for root comes up.

I have tries doing a e2fsck -p /dev/sda1 from the Boot CD from a term window - but the check comes back clean.

Any ideas why I'm still stuck even after a e2fsck?

do you have a copy of Spinrite? if you do run it to try and fix the sectors. How recently have you backed up?

There are a number of other recovery utilities that might let you get back most of the disk contents. When the HD on my workstation machine started to go toes up last year I used to ddrescue and some other tools from the PartEd Magic CD (IIRC, or maybe it was the Kubuntu rescue spin...) to get back everything but two files.

Basically all it took was a spare drive and some patience.

I've never heard of Spinrite choking did it give you an error message or did it just look like it stalled. If it gets on a particularly bad sector it will try to revive it 6 ways to Sunday. You could try clonezilla. You could try in a completly different computer or a different power supply.

What mattbatt said about spinrite also goes for ddrescue. Utilities like this are very much retry based. For example ddrescue does multiple passes, starting out reading large swaths of data and noting where there are problems. Then it goes back to the problem areas and uses a "divide and conquer" strategy to retrieve as much as possible of the rest.

The write up that comes with it is highly recommended reading and covers the strategy and tactics used, along with a lot of general technique for disk or data recovery.

Frankly it sounds like the drive itself is failing, rather than just some corruption of the data or the formatting. While I had a drive which ran for many years after mapping out some bad tracks, that's not the way to bet. New drives are cheap compared to your time and data.

So i wound up formatting the drive and starting over with LinHes 7.
Spinrite worked for me before, but choked for some reason.
I actually keep most of the data on another drive so it wasnt much of a data loss, but looks like ill have to reconfigure tons of stuff as I am sure others have had to do as well.

THe drive health is fine after a reformat and SMART reports it healthy, for some reason the drive choked when the system shut off due to a clogged fan/cooler on top of the CPU which got clogged with spray paint and dust.

spray paint you say.... that sounds like a story.... I once had a noise volume knob and grabbed a bottle of contact cleaner to fix it. It turned out to be black spray paint in a similar red and black can. The funny thing was it cleaned up the sound!!!

Just had this happen to me. Lost power while I was exiting a show (apparently the UPS can't handle the TV and the Comp).
The answer is fsck
I put in the admin password and then typed fsck answered yes to a bunch of things and DING fries are done.
