Agreed, but cables were easy to eliminate just in case. I can't imagine how partitioning could directly affect it but the fact that the problem arose after erasing and partitioning does suggest it might be related to something which I did at the time. > To the best of my knowledge this is basically only > alterable by BIOS settings(ahci), drive firmware settings or a jumper, > settings listed in ahci(4), and sata controller version. There's been no BIOS changes, apart from adjusting the boot priority order after moving drives between SATA ports. The BIOS has no settings which could affect the performance of just one drive. There's been no firmware updates and no settings have been changed. -- Mike Clarke
