    presumably that's sda6

    you didn't say how big /boot is and/or how old your cpu is

            /boot is NOT needed on newer bios that understands
            how to read mroe than 1024 cylinders

    during the boot... what does the boot up messages say
    about your filesystems

    you cannot make /dev/sda6 a "slave" on another system

    you cannot put the origina /dev/sda6 into another system and expect
    it to be sda if there is already a lower number scsi device
    ( sda, sdb, sdc is assigned but the scsi-id jumpers and which host its
      connected to

    sounds like the disk is not seen by the system

    > all of them report problem with one sector.

    i assume you mean partition ..

    sector probelms will say track-xxx head-yyy sector-zz
    which is just 512bytes of data
     
    > Do I have any way to recover some subdirectories?

    in my book ... too late to recover data from bad disks after you
    notice its bad .. similarly backup sis worthless if you
    overwrote last weeks good backup with yesterday's bad data

    - yu dont know what s good from bad data till you look at
      every single sector ... 512byts at a time .. and compare against
      a known good backup

    but if the lucky charm likes you, and uncle murphy is sleeping,
    you can read your data dozens of different ways before the disk really
    goes kapput
            - put the disk into a different working pc
            - boot from the cdrom
            - boot from the network
            - boot from the floppy
            - boot from the usb
            - boot from your-favorite-booth methods
