Is e2fsck safe

[stacker1001]

After adding tivoftpd and httpd-tt.tcl to my rc.sysinit file my Tivo 
has ceased booting. I've remounted the A disk in my PC and have 
mounted the hdd4 partition and the rc.sysinit file seems to be 
corrupt. Unfortunately it will not let me remove it (I made a 
backup copy of the file beforehand) It keeps giving me a File 
Input/Output error when I try to do anything to the file (cp, mv, 
rm, cat) The file rc.sysinit also only appears when I do a "ls" but 
when I do a "ls -al" its not there. Please help me.

Missing my Tivo
