Sounds like you may be low on ram. GOS needs a min of 512, recommend 1-2gig.

I would suggest not to use re-imaging on new sets. The parmaters are not the same between HD's.

My course of action would be to delete the Raid5 array.
Remover all HD's except drive 1.
Do a quick erase of the removed HD's
Launch the recovery console, and do a "clean install"
Once the clean install has been preformed, reboot.
Then check to see if the HD is identified correctly. If not you may have to update the GOS.
If good hot swap drive 2, wait for OS transfer, check to see if it is identified correctly.
If good, go ahead and hot swap drives 3 and 4.

With all HD showing proper capacity, go ahead and build your raid5

I do not remember what size restrictions are on GOS v3.1


Have you looked at the BIOS?
