I am getting an "Incomplete Disk" message from 3ware when booting our system. It also says that the disk will not be passed over to the OS.

Is there anyway of salvaging the data that is on the disk? The data has not been overwritten and the hard disk worked fine until I added a new array to my 3ware card.

I do have a backup from several days ago, but would like to get all the data if possible.

Any ideas?
Thanks in advance.

Not enough information for a concise answer. What array is running?? 0, 1, 5, 10 ...
How many HDDs?? Did you use 3dm (or tw_cli) to remove the bad disc?? Did you use 3dm to add the new disk then rebuild the array??

To give a little more information:
I had (notice the past tense!!) two RAID1 drives running. I had tw_cli installed on the system, but after a reboot the RAID "bios" said that the boot drives where incomplete and the system did not boot. One of the data drives was not working, but the other seemed to be working fine, but it was impossible to tell as I never got to the prompt.

I figured that if I replaced the boot drives with a new OS, I would still have access to the data drive and could rebuild it. I reinstalled the OS and then the RAID "bios" said that the lone data drive was incomplete and it was not visable at the prompt.

As I needed to get the system back up and running asap, I installed four new drives and started all over. I now have the data drive that I would like to access, but the RAID "bios" says it is incomplete. I have not yet tried attaching directly to the HDD connector on the motherboard, but I assume I will get the same result.

Does that give you enough information?

You don't need to boot the old drive. Just hook it into the system, boot the machine using the new array, then mount the partition you need off the old drive to the new and copy what you need. You may have to make sure the old drive is jumpered as slave so the machine doesn't try to boot off it.
