    Erase Server Disks

    Hi,

    I need to Erase some disks on a server before I give them away. All my usual products such as DBAN and KillDisk will not work with Raid Cards. Can anyone suggest another product please? The servers are Dell PowerEdge 2950's with a Perc 5 card.

    Thanks

    We don't have anything to read SAS, plus due to the sheer number of disks it will take to long.

    As above. Otherwise, if this is something you may do often, invest in some decent software like Blancco for that purpose. Works with raid cards fine.

    Its a 1 off. Usually an outside company does the erasing for us in exchange for the server hardware. We are not going to chuck money at it, because the servers are being given away for nothing.

    I was told by HP that if a drive was removed from a Raid array, the data couldn't be read as i was in the same position.

    Don't know if it would be sufficient for your needs but you can use the built in controller utility to initialise the disks.

    Its not working with DBAN because of the lack of drivers. initialising the disks, isn't enough really.

    How about create two volumes - one (say 40GB in size for a Windows OS install) and the other with the reminder of the capacity of the drives with everything in RAID0.

    Install Windows and then use the blank space eraser tool in Eraser Eraser | Internet Security and Privacy on the other partition to obliterate anything that might still be around.

    Have you tried Ultimate Boot CD? I've no idea if it will work on RAID but it has partitioning tools and disc shredding software on it. It's free.

    Here's what I do:

    1. Break the existing RAID arrays and reconfigure for RAID0 (striped) to reduce erasing performance.
    2. Boot with a Ubuntu Live CD (recognises most RAID controllers in my experience, including Dell PERC)
    3. Find disk device names using:

    sudo lshw -class disk | less

    4. For each device, run (for example device sda):

    sudo shred -vz /dev/sda

    Dban should recognise the controller just not when the disks are configured as an existing array.

    Our Site Manager has one of these and finds it quite therapeutic
