According to this source, "SATA 3 or 6 Gbit/s drives may be connected to SAS backplanes, but SAS drives cannot connect to SATA backplanes."
http://en.wikipedia.org/wiki/Serial_attached_SCSI
The source the wiki uses states, "SATA connector signals are a subset of SAS signals, enabling the compatibility of SATA devices and SAS adapters. SAS drives will not operate on a SATA adapter and are keyed to prevent any chance of plugging them in incorrectly."
http://www.adaptec.com/en-us/_whitepapers/tech/sata/sas_sata_unprlcompat.htm
BTW, there are vendors that sell adapters, like this one: http://www.amazon.com/StarTech-18-Inch-Cable-Power-SAS729PW18/dp/B000V72AQ4 that supposedly allow you to connect a SAS HDD to a SATA port.
Why not just exchange the HDD?

Thing with this cable is that the device/controller has to support sas to sata connection, as per what I've read in the comments below http://www.amazon.com/StarTech-18-Inch-Cable-Power-SAS729PW18/dp/B000V72AQ4 , quote "What may trip up some folks is that this SAS connector will allow you to connect a SATA controller to a SAS drive but nothing will happen unless the controller specifically works with SAS drives."
