    Help need to fix server disk errors.

    My ubuntu server is throwing errors and it looks like the drive is failing.


    I searched for how to fix the drive errors and tried the following but I can get it to work.

    here is what I tried

    > df -h

    returns among other devices. ( note /dev/SDB does not show up but is assigned as md127 or should be If I set the rad up correctly)

    /dev/sda
    /dev/md127 ( was a raid drive but I removed one of the drive and disabled the raid )

    > umount /dev/md127 ( states drive is unmounted)

    > fsck -A /dev/md127 ( aborts with msg drive is mounted)


    not sure what I'm doing wrong.
    here are a few of the error msg.
    --
    ata3.01 exception fail read DMA
    BLK-update dev sdb io error sector 11.......
    --
    also I have a mapped/samba drive on the ubuntu server to my windows pc and when I try to copy some files from the server to the pc a whole lot of error msgs appear on the severs monitor.
    --
    I also get error about the MYSQL program, ( not sure where the MYSQL programs are installed either on the SDA or the SDB drive) but I was able to backup the database.


    would using clonezilla to clone the drive as is be recommended? I could get some of the data off the drive if I cant fix it. I think clonezilla attempt to read the bad sectors.
