Dear experts,

I have a T61 laptop with WinXP SP2.

The problem is that the SD slot does not work with some SD flash memory
cards.
Cards of 16 or 32 MB work fine (so I assume that the slot and divers are
ok) -
but 512 MB card gives error 10 in device manager.
A 1 GB Sandisk micro SD card (in SD adapter) is not even detected.

Is there a limit of card size for WinXP SD driver?

All tested cards are formatted and working well with a SD to USB adapter.

The limit is not with XP...probably a hardware limitation of your laptop...
you may find the easiest solution is just to buy and external (USB)
cardreader

Thanks for all replies.
If I understand correctly, the SD adapter of this machine is not just an
internally connected USB reader, as in older models.
It is directly connected to PCI and capable to run SDIO devices.
So I hoped that it can work with new SD cards of 2 GB or more.

I've sent this question to Lenovo support, still waiting.
By the way, USB readers also seem to have some capacity limit...
