Adaptec controller initialising drives
 

When I got a new Adaptec controller (3805) I had to initialise the drives before the controller would recognise them. There was a warning saying any data on the drives would become inaccessible after doing this.

I never had to do that when attaching drives to my 3ware controllers (I've got one and owned 2 before it).

I don't recall that being the case with the old Adaptec 2410SA I owned either.

So have the drives on my new controller become initialised in such a way that I will not be able to read the data on them from the 3ware controller or the onboard NVidia controller? Now I can't take drives from my 3ware or Nvidia controller and just move them to the Adaptec controller either, which is stupid.

Note that with both the Adaptec controller and the 3ware controllers I am not using the hardware RAID features, I am just using the drives in a JBOD arrangement as far as the controllers are concerned (mdadm on top with Linux).
