I just reread that this is now SATA. New versions of hdparm and smartctl can tell you if the drive is Advanced Format, and if it is, then I recommend redoing the partition scheme so it's 4K aligned. And so that it has an MBR gap. The current way to do this is have the 1st partition start at LBA 2048. -- Chris Murphy

I can redo the partitions, but I'm not sure how to tell fdisk to start a partition at LBA 2048. -- Bowie

What am I looking for?# smartctl -i /dev/hdg | grep -i sector Sector Size: 512 bytes logical/physical That's what I get, but it's an SSD so it's a lie.> I can redo the partitions, but I'm not sure how to tell fdisk to start a > partition at LBA 2048.Let's figure that out only if it's an AF disk... -- Chris Murphy
