If it is grounded, the controller complains about 40 wire connection, no longer. But, I've learned, the 80 pin connection is recognized by the pin 34 of the IDE connector. I did tested two solution in the process:Īt first it was not not a good choice, because the motherboard built in controlled detected the connection as 40pin cable. I,ve installed a SATA drive to the ATA motherboard, a while ago.
