Subject: need help with getting into a corrupted sub directory

Hi,

I have a ext3 filesystem created inside a problematic seagate ST3500320AS
drive. The drive will just shut itself down automatically whenever it hits
any read error. Only way to wake it up it to cold power off / on the
computer.

Now, my ext3 fs is /dev/sde2

I can mount it without any error:
mount /dev/sde2 /tmp

then, I can 'cd' into /tmp to get a sub directory listing.
let's says there's

Hello
World
users
public

now when I do 'ls public',  I get:
EXT3-fs error (device sde2): ext3_get_inode_loc: unable to read inode
block - inode: 26181633, block=26181634
ls: cannot access /tmp/public: Input/output error

'sde' will disappeared from the system, need power off / on can get it back.

After cold boot, I know there's a subdirectory called "EL" inside "public",
if I do a 'ls public/EL',
I get:
EXT3-fs error (device sde2): ext3_get_inode_loc: unable to read inode
block - inode: 26181633, block=26181634
ls: cannot access /tmp/public/EL: Input/output error

Is there any way I can get into subdirectory of "public" without the need of
read inode block 26181633/26181634 ?
Is it still possible to get a full subdirectory listing of "public" ?

Thanks a lot,
kyle
