Raid 10 Unable to add a new disk

[pa67]

Hi,

I have an old Asus Z87MPLUS motherboard with 6 SATA ports. The OS is windows 7 pro. Two ports are used for ssd and dvd and the other four for a raid 10 (4 x 2TB). I changed a disk because it was faulty with a new one. The disk was successfully added to the existing raid and the rebuilding started without problem.
After the rebuild I did a reboot and the disk disappeared, the RST utility indicated a free sata port and the fourth disk was at 0GB. After a new reboot the raid was ok again, the rebuild started but at 65% the disk disappeared again.

Could it be the sata cable, the power cable, the power supply, the motherboard or the new drive that have some issue?

Thanks
