Is that one of those WD drives that falsely reports its physical sector size as 512 bytes?
From the Scorpio blue specs, if I divide the capacity by the number of sectors, I get 512...
all these new 'advanced' drives look to the host like they have 512 byte sectors.... its just that they pack 8 of them internally into a single 4K sector. if you don't ensure that your partitions start on a 4K (8 sector) boundary, then committed random writes are very slow as your logical file system blocks will span multiple physical sectors
