Raz:
The 3ware (at least my 9500S-8) keeps the info about the disk and how
it fits into the RAID array on the disk; I think in the DCB is used
for this. You can (and I have) unplug the disks, then connect them to
different ports and the array will still work fine.
When you are adding a disk from a different array it probably has the
DCB from that array. This is conflicting with your new array. I would
do as the Dan suggests, and clear the disk.

Two thoughts:
1) Maybe test the disk in another machine and see if it's still good
2) Maybe wipe the disk clean in another machine with something like:
dd if=/dev/zero of=/dev/sdb
...but be very careful to get the right disk (IE, you may not
need /dev/sdb, you might need /dev/hdd or a number of other
possibilities).
