Not only that, but I've found that the Seagate ST3500413AS (500 GB SATA 6Gb/s) 
won't work on my Intel SASUC8I HBA (basically an LSI SAS3081E-R, which uses the 
mpt driver). It'll work just fine on an AHCI port, but apparently the HBA can't 
successfully autonegotiate the 3 Gb speed.

No jumper is available to force 3 Gb operation. If I place a jumper on the 
typical Seagate speed limiter location, I get 1.5 Gb operation (but that's 
actually undocumented for this specific drive family - the documentation claims 
jumpers are unnecessary). I haven't tried the 1.5 Gb mode with the HBA, though.

Would a 6 Gb SAS HBA work with 6 Gb SATA drives?
