Problems with GIGABYTE motherboard and IDE bus

[scs]

Hi, i have a GIGABYTE GA-6BXE motherboard. In the ide connecto i have a HP 12XCD RW and a HP CDROM. The writer it´s configured as slave and the reader it´s configured as a master. In my house sometimes i have "electrics downs" and when i power on the computer my motherboard don´t detect the CDRW and the CDR. I probe to change the master to slave and i probe to plug only the CDR, too. But my motherboard don´t detect the unit´s.

I need help.

Sorry for my english. ;-)
