Replacing Hard Drive on Snap Server 4200

I've got a failed hard drive on a Raid 5 array. It appears its not hot swapable. I've got the replacement drive that is the same as the failed. When I shut down the server and replace the drive it sees it but does not do anything. If I put the old drive back in it starts to rebuild, I can see the shares, but after a bit it fails.

I'd image the failed drive to the new one with linux and dd_rescue
then plug the drive in hot and allow it to rebuild, It may work.

I like that idea, but not sure how to go about it. Do you have any links on how to do this?

ddrescue works in two passes. On the first pass, it grabs all the good sectors.

    ./ddrescue -n /dev/old_disk /dev/new_disk rescued.log

The second pass grabs the error stuff, reading the info from the rescued.log

    ./ddrescue -r 1 /dev/old_disk /dev/new_disk rescued.log


I'd download ubuntu, boot up the cd, you have to select, with the package manager ddrescue and install it.

then you need to run instead of the above ddrescue, sudo ddrescue -n /dev/sda /dev/sdb /home/rescued.log

Assuming that sda is the data drive and sdb is the new clean working drive.

you most likely will not need to do the second pass, once the controller card recognizes it's brother in a degraded state, it's going to try to rebuild it.
