My HP notebook has a slot to take an SD memory card.

I have used this with an adapter to read the micro SD card from my phone.

If there is a 1Gb micro card inserted the computer recognises it and I can format,

load, delete files as I wish.

2Gb or larger, I now have an 8Gb card and the PC does not see it.

I have tried the adapter in another computer at my local shop and it works.

Why doesn't it work in my PC.

The notebook is an old HP NX 8220 running windows XP

had the same problem with my older laptop. i brought an adapter [100 baht?] that inserts it into the usb slot. worked fine

Update the driver for your card reader in your laptop. The old readers would only recognise up to 2GB. Very easy to do in your device manager.

Thanks for the suggestions.

I have tried a USB card reader. Plugging in the micro SD card directly it is recognised,

but using the SD/Micro SD adapter it is not.

The fault is not with the SD/Micro SD adapter, as I have tried it in a new PC, and there is no problem.

I found newer driver, 2006, for the card slot, but that did not help.

I now need to find a USB card reader that will accept SD cards, also the CF cards used in my camera.
