Zorin OS at startup is doing fsck it offers me the option of Canceling check, Fix errors, or Ignore. However the splash wasn't really telling me what it was doing so I started in recovery and when it ran fsck it shows:

*** indicates a continuance of blocks: posting all the numbers would require a lot of room, Needless to say that the amount of them is high. it attempts to fix this at every login, then it goes to pass 2 where it tells me:
Yet again next time I start up my computer I am greeted with the same errors (in most cases some of the same inode block numbers are present) and ever since this developed I have seen the speed of almost every application slow (internet,banshee,playing a dvd, even something as simple as opening Gedit) and most times I end up having to shutdown.

I've tried searching through google, And I found lots of tutorials explaining how the inode table works or how to set the size during install ... But not really any troubleshooting that seems like my same problem.

I am thinking I may have to do a re-install, But if there is a way to correct the issue I would rather do that.

(side notes that may be of importance: My filesystem is EXT3; I recently had to delete Mint as it wouldn't start AT ALL -just a black screen after GRUB ... removed it with gparted in Zorin-; Using Zorin as ROOT seems to be smooth- I know it is not recommended but hey, it works)

I'd boot into runlevel 1 or single at the bootloader prompt, let it fix all errors and reboot. If no errors occur (lets hope you're not confronted with the exact same inode numbers again) and run a 'smartctl -t short; smartctl -l selftest'. If results are not positive (not that SMART is the definitive answer to Life, the Universe, and everything else including all hard disk failures) you know it's time to back up important stuff and figure out if more testing is required, if you should just nuke the file system or that buying a new hard disk would be preferable.

booted at runlevel 1 and fixed the errors ... I haven't had to fix on start yet, But I am still going to do smartctl (Which if I got the right thing is SmartMonTools) as recommended. Laptop only has about 20 minutes battery life right now, So I cannot do it immediately. So I am not marking this as solved yet. Tomorrow when I can plug it in I will give it a shot and see where I am at. Thanks for the response.

So I am now at my aunt's house, with constant connection. I ran fsck (on my own at boot, not by force this time) and saw that something was failing to start (I didn't catch the name fast enough) on the plus side it said:

I have yet to update from ubuntu 10.10 to 11.04 so update in progress was not true (to my knowledge)... I put in a live cd and resized Zorin (with gparted) to take up all my HD instead of just 25G (roughly 1/2) of it, exited and then booted as normal and installed the 11.04 update (as well as a long list of updates I've been neglecting due to lack of connectivity) so far I haven't gotten any of the errors as before and it has not run checks at startup. I have no idea why, but that is what I did and it seems to work. As this is no longer an issue I will mark as solved.
