    Re: Boot Loader failed to install

    The previous mdstat showed the raid devices as sdc and sdd. This one shows sde with the other device removed.

    Not only that it changes the devices raid members, it also seems to be dropping one of them.

    Are your disks OK? Your system as a whole? You mentioned that BIOS failed to recognize one disk once. Or maybe more times?
    Darko.

    Re: Boot Loader failed to install

    BIOS dropping a drive happens, but it's not a consistant error, so I dont know how to diagnose it. If it truly is a problem over the next few cycles I'll make that it's own issue. So my first act should be to verify a properly configured RAID, right? once that's complete I can tackle the bootloader issue.

    Re: Boot Loader failed to install

    Have you tried with another sata cable?
    Connecting the disk that is being dropped to another sata port?

    I would connect the disks planned for raid in the first two ports anyway, so they would be sda and sdb.

    Re: Boot Loader failed to install

    I'm still here, after I got back from vacation I was too busy to do much of anything. I have swapped my cables around so the two raid drives are set as sda and sdb. however something still isn't right. gparted fails to recognize one of the 3TB drives, /dev/md1 as well as a 160GB drive

    here is the output of

    /sdb is my old backup drive. /sde and /sdf are my flash drives. I don't understand what it says about /dev/md1.

    also here is the output of
    Code:
    cat /proc/mdstat
