how? via USB?
well both should recognise it. there is a driver on there too,
if it's not installing try using the PC companion which will include a driver installation
on my xperia S I find it painfully slow anyway
why not just just file expert or ES explorer and FTP from the wifi network in your house
it picks up shared drives without any problems in my experience.
then there is no USB issue and it's just a wifi push to the network drive
