THANK YOU! To all of you who helped with advice. I finally waded through 70MB of log files from the last 6 months on my server and finally figured out a way to get the correct order. I had a few logs of 'fdisk -l" which contained the Disk Identifier. I matched that up against where I had the drives in the enclosure and the ata.#'s. I came up with a short list of drive letter ordering and just kept trying them with four drives at a time moving the _missing_ drive around. Finally, it came up. I'm now up with four drives and RO filesystem. I'm going to try and backup as much as possible off-disk. Then I'm thinking that I need to add the "missing" drive back in and re-build. Correct? Thank you again. Tim On Fri, Sep 18, 2009 at 1:17 PM, Guy Watkins <guy@xxxxxxxxxxxxxxxx> wrote: > When you did the create, it trashed 1 drive. I don't know which one.
