It would be nice to be able to do read tests with raw
devices while having data on those disks.

It takes a lot of time to clean the disk, take a
measurement and restore the database just to make a
simple read IO measurement.

    currently u can read a raw device without destroying the
    data. i am not quite understand why u need to clean the data.

    From User Guide "Physical drives are displayed with a blue
    disk icon and the name PHYSICALDRIVE:n (only if they
    contain nothing but free space)."
    If I have a drive with a partition it won't show up in Iometer. I
    have to delete the partition in order to be seen by Iometer.
    Remember I'm talking about raw devices and the partition
    does not contains any filesystem.
