Hello, My co-worker ordered a Samsung 840 PRO series SSD for his desktop but we found 9.0-rel would not probe it and 9.1-rc3 shows some errors. I got past the problem with a workaround of disabling AHCI mode in the BIOS which drops it to IDE mode and it detects fine, although runs a little slower. Is there something I can try to make it probe properly in AHCI mode? We also tried moving it to the SATA data and power cables from the working SATA HD so I don't think it is the port or controller driver. The same model motherboard from another computer did the same thing. Thanks. dmesg line when it is working: ada0: <Samsung SSD 840 PRO Series DXM03B0Q> ATA-9 SATA 3.x device dmesg lines when it is not working: (hand transcribed from a picture) (aprobe0:ahcich0:0:0): SETFEATURES ENABLE SATA FEATURE.
