Strange Files Created, FSCK problems: how to deal without single user mode (/unmounting disc)?

[Bigbrother]

Dear all,

 Today I found out (due to my backup process failure) that 
 some strange files were created on a users dir.

 Specifically:

 --wx--s-wx  16217 1062905872  1311669378    1061708166 Jan  1  1970
.irssi
 b---rwx--x  16240 root        wheel       174, 0x3f590067 Jan  1  1970
.mc


These entries were supposed to be directories, but somehow they changed
to something else.

I tried to remove them:

rm .irssi
override -wx--s-wx  1062905872/1311669378 sappnd,arch,schg,uappnd,opaque
for .irssi? y
rm: .irssi: Operation not permitted

 rm .mc
override ---rwx--x  root/wheel schg,uappnd,nodump for .mc? y
rm: .mc: Operation not permitted


Without success!




 I fscked the disc (note that his is an active disc with many users) and
the report is located at the end of this email. Because 
 the disc is read-write active changed are not written on the disc.


 My questions:

 1) Have you got any clue how a healthy IDE disc can cause and corrupt
files on the file system?

 2) How can I fix the problem WITHOUT rebooting or without UNMOUNTING
the discs? If I fsck and
     instruct to actually fix the errors, will they be fixed, or it
might crash corrupt the whole file system?

 3) How serious is this problem? Should I start worrying, even though
nothing else strange exist?





Thanks in advance,

BB
