I made the same, miserable experience. I tried to repartition the hd.
As i realized later, i made a fault by setting the unit size in fdisk to <sectors>
and created partitions, that didn't start and end on cylinder boundaries. I never recognized
this error, because (older) fdisk gave no warnings and i had ext fs running stable
for 4 months. When i now changed to ext2 fs, mke2fs didn't correctly allocate
my 32 MB root partition. While there had been ~8MB left on that fs (output from df
and e2fsck), write accesses had 'no space left on device' as result. Beside that,
i did get these 'bad directory entry errors' from time to time
When i tried to mount that fs from the rootdisk (from tsx-11:/pub/linux/GCC/rootdisk)
i got a similar error as you described. When i ran fdisk from that rootdisk,
i got many warnings about physical and logical sectors not beeing the same.
So i had to delete all the old partitions and started a new installation. I'm not done
now, but i didn't have any problems creating my ext2 filesystems.
