Based partially on MS standard spec quotes from Alex Dubov. As any code that works with user data this driver isn't recommended to use to write cards that contain valuable data. It tries its best though to avoid data corruption and possible damage to the card. Tested on MS DUO 64 MB card on Ricoh R592 card reader.

If you say Y here, the MemoryStick layer will assume that all
|
|
cards stayed in their respective slots during the suspend. The
|
|
normal behaviour is to remove them at suspend and
|
|
redetecting them at resume. Breaking this assumption will
|
|
in most cases result in data corruption.
|
|
|
|
This option is usually just for embedded systems which use
|
|
a MemoryStick card for rootfs. Most people should say N here.

Say Y here to enable the MemoryStick Pro block device driver
|
|
support. This provides a block device driver, which you can use
|
|
to mount the filesystem. Almost everyone wishing MemoryStick
|
|
support should say Y or M here.

Say Y here to enable the MemoryStick Standard device driver
|
|
support. This provides a block device driver, which you can use
|
|
to mount the filesystem.
|
|
This driver works with old (bulky) MemoryStick and MemoryStick Duo
|
|
but not PRO. Say Y if you have such card.
|
|
Driver is new and not yet well tested, thus it can damage your card
|
|
(even permanently)
