Go into device manager and "Scan for new Devices" to see an insertion or ejection. \f1 The CF cards use a hard disk IDE driver that does not expect hot plugging. Sonnet is developing an update that will allow hot plug.
Some CF cards are seen as non-removable disks. Ejecting these cards will cause the whole Qio to eject. Restart the computer to restore functionality to the Qio and do not use "Eject" to remove CF cards.
You need to download and install the Sony SxS UDF Driver, available here http://pro.sony.com/bbsc/ssr/cat-recmedia/resource.downloads.bbsccms-assets-mkt-recmedia-downloads-upgrades.shtml
