Memory Stick

The Memory Stick is a proprietary memory device, currently only used in devices made by SONY. The current issues are USB devices and work with all recent kernels. After loading the usb-storage you may mount them as SCSI devices, often as /dev/sda or /dev/sdb.For older laptops see the appropriate pages at Linux-on-Laptops.

There is also a SONY Memory Stick Floppy Adapter - MSAC-FD2M. I don't know whether this works with Linux.
