EXT2-fs error

[Igor Mozetic <igor.mozetic@uni-mb.si>]

I found the following in /var/log/kern.log:

kernel: EXT2-fs error (device ide0(3,4)): ext2_readdir: bad entry in directory #198657: rec_len is too small for name_len - offset=868, inode=198683, rec_len=32, name_len=56 
kernel: EXT2-fs error (device ide0(3,4)): ext2_readdir: bad entry in directory #198657: rec_len % 4 != 0 - offset=868, inode=1751343459, rec_len=13157, name_len=56 

What does this indicate? Which device (hard disk partition) is ide0(3,4)?
Is doing: e2fsck -c /dev/hdXY enough to resolve the problem?
