No, disk 1 is using the onboard SATA controller, disk 3 is on an LSI.
Replace SATA cable for disk1, also replace power cables, if not available swap power cable with another disk and see where the problem follow, for disk3 you can just swap cables with a different disk on the LSI.
After booting search the syslog for mpt2sas, then click next until you find the line where it mentions the firmware.
