A Western Digital drive on the master port! Please note how my ata busses change from ata7,ata8 to ata3,ata4 , this immediately solves my question how come my drive order mangles up at times. I tried to change the master/slave order aswell, so make the Seagate master and the WD slave, no success, disks wont get detected. Guess my only way out of this is to use both drives on seperate channels. Unless there are patches I can try of course :) Patrick - To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
