Subject description: bsd partition seen as ext2		  
I am having some weirdness with a BSD partition.

I get this on boot up:

EXT2-fs warning: mounting unchecked fs, running e2fsck is recommended

EXT2-fs error (device sdb4): ext2_check_page: bad entry in directory #2: rec_len is smaller than minimal - offset=0, inode=0, rec_len=0, name_len=0

I have two identical hard drives and a total of 4 BSD partitions
fdisk shows them as FreeBSD.
gparted shows FreeBSD as unknown
except the one in question it shows as ext2???
I've deleted them, re fdisked, made a new fs??
still comes up weird on that one.
any ideas?

You can format a partition without changing the type ID

I think they should correspond. Do they?

Also the cylinder boundary endings don't look a happy sight. What's with that?

It's a mystery.
why is it FreeBSD on fdisk but non on gparted?
I don't know any other way to change the ID but fdisk and then put a new fs on it.
odd.

as for the partition boundaries, dunno.
I've never had any microsoft on my computers for
about 10 years so I cannot blame them.
I generally use fdisk to partition, though maybe I was using
solaris at the time of cuting them up.

I'll have to dig around and see how puppy checks the drives, on startup
obviously not fdisk.

Subject description: pulp linux boot error messages		  
pulp 0.1 (2.6.21.7 kernel, based on puppy 4.2 I think).

Pulp is installed frugally on /dev/hda7. Works mostly despite errors.
Possibly related to Youtube getting 'stuck' after a while (starts over,
stops after 2 sec) and I need to restart the browser (first I clear
history). Sometimes when I switch from console to X, the top half of X
is black with a few colored streaks and I need to reboot.

Error messages at boot time:

EXT2-fs error (device loop1): ext2_check_page: bad entry in directory
#18448: unaligned directory entry - offset=0, inode=48896, rec_len=3329, name_len=84
A similr line for #18461 with other numbers for inode etc.

EXT2-fs error (device loop1): ext2_readdir: bad page in #18461 (and 48)

There is some junk in /lost+found all from 2011-04-07.

From another operating system located on another partition I ran efs2ck
and it found no problems. e2fsck /dev/hda7
