hp dv9540 laptop second harddrive not detected

[Niels Larsen]

I am sorry, but I thought that I was talking to the list, but suddenly I am in 
private discussion, and that's not what I want - so I am a little confused? 
When I see a reply to my question, I automatically answer by "reply"?
***************

Here I try to repeat my "thread", with same subject:

I have a new HP DV9540 laptop with 2 x 120 gb harddrives.

I cannot detect the second drive in ubuntu 7.04.

I succeded in detecting it when using systemrescue cd, and then I could format 
it with gparted as ext3.

But in ubuntu I cannot see it (and in knoppix I cannot see it).

It is not to be seen in the /dev directory.

And when I run "df -h" it is not to be seen.

The next day /dev/sdb and /dev/sdb1 was gone again.
I even got error when booting about sdb1 problem, and tried what was 
suggested.
Then I tried to run the "testdisk" program, but it could not see /dev/sdb 
neither.
Then I ran gparted again, which however could see the sdb1, and I reformatted 
sdb1 to ext3 (again), and then ran check and everything answered that all was 
well.

Then it worked.

But today the same happened.
When I booted up I got following:

"fsck.ext3: No such file or directory while trying to open /dev/sdb1
/dev/sb1:
The superblock could not be read or does not describe a correct ext2 
filesystem. If the device is valid and it really contains an ext2 filesystem 
(and not swap or ufs or something else), then the superblock is corrupt, and 
you might try running e2fsch with an alternate superblock:
e2fsck -b 8193 <device>
/dev/sda3: clean, 115896/4889248 files, 829560/9765511 blocks fsck died with 
exit status 8
* File system check failed.
A log is being saved in /var/log/fsck/checksfs if that location is writable.
Please repair the file system manually.
*A maintenance shell will be started.
CONTROL-D will terminate this shell and resume system boot.
Give root password for maintenance
Or try Control-D to   continue: "

Then I tried boot password, and ran:
e2fsck -b 8192 /dev/sdb1
but nothing happened, except some help options showed up.

Then I rebooted and came into ubuntu, but /dev/sdb1 was not there, and 
the /var/log/fsck/checkfs was not there.

:-?
*************************
Now I have googlet a lot, and was told to change all UUID=... to 
respective /dev/sda's in both /etc/fstab and /boot/grub/menu.lst.

I have done that, but it does not help, I still cannot se the second internal 
harddrive (/dev/sdb1)
*******************

I am sorry to make this message so long :-(

It seems that my problem is shared in some way with many other people, but I 
cannot follow all the suggestions I have seen in my googling.

My laptop is brand new!
