It's a normal ext file system check, but if it is ext3 as it is likely to be rather than ext2 (the original, which might be helped by these file checks)
--there is probably a question as to whether or not any journaled file system needs these checks (ext3) being an example of such a file system
You can also change the interval of fs checks
--and if you have smartdrive enabled in the BIOS already and possibly have Linux smart tools installed, why even do any fs checks http://hack2live.blogspot.com/2009/02/u ... oring.html
But it is a minor annoyance on the occasional boot
--have a donut or a longer coffee break , while the system boots..
