I just got an areca 1220. I went from having 3 tb drives in raid 5 to 4 just yesterday. After migrating and activating the array I booted back into windows. The disk manager shows that it is split as 1.8tb 1xx gb and 750 or so gb. I have >2tb support enabled in the controller firmware. I see no option to change the partition style to gpt which i guess is why this isn't working. The array is being used as my boot drive for vista x64
 
Did the array finish rebuilding? It took 12 hours when I went from 3 to 4 one terabyte drives, even though I was able to use them while they were rebuilding.

I wasnt able to use the space while migrating.. i had to reboot after migration was finished and expand the partition (im also running Arc-1220)..

unfortunately OP, I didn't come across your problem... I'm using x64 GPT on my 2.54TB (4x400GB wd re2 wd4000ys) volume.

my guess is you used the other >2TB support solution (that can be read in 32bit OS)... that splits it into two visible drives from what ive heard

yes it finished migrating and activating, which took >18 hrs and then 1.5hrs to activate. So when I created the array I forgot to use lba64 or something? From what I've read while trying to figure this out you cannot boot from a gpt partition? I do hope that that is completely incorrect because I really wanted my 5tb raid 5 array to be for my os as well.
 
So here is where I stand now. I have a 4tb raid 5 array on my controller with the latest firmware for both the bios and the controller. I am trying to use the volume to install a copy of vista x64 sp1 to no avail. When I get to the partitioning screen I see 2 unallocated volumes. I am completely at a loss now
 
After you did your capacity expansion, did you extend your volume?

If IIRC the extend process is:

diskpart
list volume
select volume x
extend
 
yea I did extend it. I have kinda given up and gone about it another way. I was using the 1.43 fw for my controller, but an efi "mac pro" fw is available, do you think that might be required for booting a gpt array.

I think the way I have it set up will be better in the long run anyhow, with my os on a single drive I can re-install when I switch out mobos without screwing around with the rest of my data.
