[BTW: Why do you have to write such long lines? I've asked you about this before]. Well, that was clever after being warned, wasn't it? fsck works on the character device and ignores the contents of cache, so it can see deficiencies where none exist. If it "fixes" these deficiencies, it corrupts the disk. >> I booted into single user mode and ran fsck again which it found >> more errors and i told it to fix them.

To be 100% sure, you need to compare them with the original, or to read in your last backup. In practice, though, it's unlikely that you've damaged any files which hadn't been modified since the last mount, and that includes most of the binaries. You could go looking for ones which have been modified round the time that you did the fsck, but I don't expect you'll have much trouble.
