I have just run into the same problem but I can probably confirm that it is
not the hardware. I have an R61 running Vista Bus who's SD card reader works
fine on a 512Mb card and an X61 also running Vista Bus that also works. When
I stick the same card into an R61 running XP pro - no go. I get the boing to
say that the card has been inserted but it doesn't appear as a drive.

So, the problem would seem to be XP's drivers rather than the hardware. Of
coursa, XP says it is using the latest driver. So, perhaps, Lenovo have an XP
version?

Thanks for sharing, Kenn.
The flash drivers for T61 are not developed by Lenovo.
They are from Ricoh (I guess). I got the latest from Lenovo site.

Stuffing the card into an external USB reader works perfectly well. What is
the point of having a built in reader that doesn't work?

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.
A1 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.

There is a possible hardware limit on the SD slot.
