Here's what I see on a 2.6.32 test box containing a drive from the same
family as yours (1TB, less cache):

scsi 2:0:0:0: Direct-Access     ATA      WDC WD10EADS-xxx xx.x PQ: 0
sd 2:0:0:0: [sdc] 1953525168 512-byte logical blocks: (1.00 TB/931 GiB)
sd 2:0:0:0: [sdc] 4096-byte physical blocks

What controller are you using?  If it's a SAS or RAID controller,
chances are that they got their SCSI-ATA translation wrong.  I have
worked with several vendors to get SAT issues resolved.
