FreeBSD 8.2 amd64 ahci(4) and siis(4) were updated 2011-05-15. <JMicron JMB363 UDMA133 controller> <SiI3132 SATA controller> <Port Multiplier 37261095 1706> Connected a shiny new Hitachi 3 TB disk to JMB363 (no PM): ada11 at ahcich1 bus 0 scbus5 target 0 lun 0 ada11: <Hitachi HDS5C3030ALA630 MEAOA580> ATA-8 SATA 3.x device ada11: 150.000MB/s transfers (SATA 1.x, UDMA6, PIO 8192bytes) ada11: Command Queueing enabled ada11: 2861588MB (5860533168 512 byte sectors: 16H 63S/T 16383C) Should connect at 300 MB/s but says 150. smartctl is not happy: /dev/ada11: Unable to detect device type Smartctl: please specify device type with the -d option. Use smartctl -h to get a usage summary Attempt to read disk with dd does not work. ahcich1: Timeout on slot 0 ahcich1: is 00000000 cs 00000000 ss 00000001 rs 00000001 tfd 50 serr 00000000 ahcich1: Timeout on slot 0 ahcich1: is 00000000 cs 00000000 ss 00000001 rs 00000001 tfd 50 serr 00000000 ... kill -9 dd process, wait for ahci to eventually give up, unplug disk from JMB363, plug disk into 3132 controller via 3726 PM (ada11:ahcich1:0:0:0): lost device (ada11:ahcich1:0:0:0): removing device entry siisch3: SNTF 0x8000 siisch3: siis_wait_ready() calling DELAY(1000) ada11 at siisch3 bus 0 scbus3 target 2 lun 0 ada11: <Hitachi HDS5C3030ALA630 MEAOA580> ATA-8 SATA 3.x device ada11: 300.000MB/s transfers (SATA 2.x, UDMA6, PIO 8192bytes) ada11: Command Queueing enabled ada11: 2861588MB (5860533168 512 byte sectors: 16H 63S/T 16383C) Siis talks to it at 300 MB/s, smartctl works, and dd is reading from it. Ahci talks to Hitachi 2 TB okay, not sure what is different with 3 TB.
