My wireless CF card (see sig for specs) identifies itself as a D-Link DCF-660W card and will occasionally mount as Anonymous Memory.
If I remove and re-insert it, it will mount correctly.
Usually this happens right after I remove a regular CF card.
This just started to happen recently, and I don't really have an explanation for it.
The only thing I have done different lately is to install pdaXqtrom, but I wouldn't think that wouldn't have any affect on it.
As far as the card working, no problems at all.
