    I have a highpoint 4322 in my Mac Pro. Connected to it are 8 hard drives in RAID 5 mode which equal out to 7TB of data. I want to back up my OS and and re-install it.

    My question is will I lose my data on the RAID if I do this? I plan on downloading the latest drivers and installing them for the highpoint 4322 and just connecting the drives back up. I feel that this should work but any insight will be helpful.

    Assuming you don't re-initialize the array, then the data will remain. :D

    I'm not sure why you'd need to do this anyway (re-initialize the array, as you've not indicated it's failed or failing). I presume the OS is on a separate disk (so there'd definitely be no need to perform such a step).

    Even if the OS were on the array, a re-installation wouldn't hurt, but you can't reformat either, unless it's a separate partition on the array (i.e. you made a boot partition of the outer tracks, typically 10%, though in your case, it wouldn't even need to be that big; say 250GB is usually more than sufficient for OS and application data).
