Hi,

I have a few 128GB SSDs that are RAID5 and was wondering if I reformat a machine that is running the OSX software raid will I just be able to remount the those as they were prior to the reformat?

Hmmm, I'll try simplify lol....if reformatting a machine that has software raid, can those RAIDed drives just kick off from where they were.

Ok, still not sure if that makes sense..but hopefully someone will understand.

Thanks.

If it is a software RAID, and you reformat the entire machine, you will lose the OS and the software RAID created by the OS. I am not familiar with OSX RAID software, however it is pretty simple to do in a Windows environment. RAID5 might be a bit trickier with standard Windows desktop OSs though. If you have a machine that can handle it on the hardware level, I would recommend that. I usually default to hardware RAID when possible. That way, the machine keeps track of your RAID array(s) despite what happens to the OS.

Best option here would be to back up the data to an external storage of some sort (HDD or network storage) and proceed from...

Yeah, thanks mate, I figured that might be the case, I also have a 16GB HW RAID5 for my Media, the software raid is mainly for temporary holding and stuff so it's not really that big of a deal, I just thought if it would carry across after a format that would be great, but I guess not!


Thanks again.
