[ubuntu-uk] SD card (reader) mysteries

[alan c]

I bought a multi card reader (external USB) some time ago for use with 
CF cards which I was using at the time. I have recently  begun using 
SD cards and the first ones were 16MB and 1GB SD.

The 16MB has always been recognised immediately via the card reader 
and kubuntu (6.06, 6.10, 7.04) but the 1GB cards are only recognised 
intermittently. In fact I had one replaced at the retail shop. The 
replacement did not get recognised either(!)

I now have additional 2GB sd cards and again they are sometimes 
recognised, but mostly not.

Same happens in 'doze XP, intermittent and unpredictable. Sigh.

I sort of conclude that the card reader is old technology and I need a 
newer one, which hopefully will handle larger SD better. (?)

It is not a question about mounting the card, it is simply not seen as 
a card device, although the card reader is shown ok in
lsusb.

The cards all work ok in their respective  units - a camera and DAB 
radios etc, and can be seen and downloaded via usb from their units, 
but not (usually) from the card reader.

I would be very interested in comments - SD standards seem to be a bit 
of a nightmare according to wikipedia.
