Can you use a separate PSU to power two of the four drives and see what happens? Just power up a PSU as directed in the following webpage and connect two of the harddrives to the PSU. http://modtown.co.uk/mt/article2.php?id=psumod > Would it make sense to downgrade to 1.5 Gbps via a boot option? I don't know. Till now all the problem cases have been isolated to a specific controller / drive combination (sata_promise and newer seagate drives) or hardware configuration problem (most of them being PSU issues), so I don't think we need such option yet. If you have a problematic hardware which pukes on 3.0Gbps, libata should do the right thing after complaining a bit which IMHO isn't too bad. -- tejun - 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
