Sounds like it might be some bad blocks, but about doing the fscks.. fsck let's you do fscks on a mounted partition, in fact, according to the manpage it let's you even fsck a mountpoint ie 'fsck /'.
You can boot into single user mode, make sure no read-write/write files are open, and type 'mount -o remount,ro /' that will remount your root filesystem read-only. Not sure if it will work or not though, cause you might run into problems with open files that you can't really close, but give it a shot and tell us how it goes. This is similar to what happens when you boot up, your / filesystem is originally mounted read-only, then after checking the filesystems it does a 'mount -o remount,rw /'. You could also boot from one of those single-floppy linuxes, or from an installer cd, and do what you want with the filesystems from there. J.
