8 gig sd card not being recognised

Hi

I have 2 8 gig sd cards, 1 Transcend and the 2nd a Sandisk, however Windows 7 refuses to recognise them in either the card reader or the usb adaptor. XP reads them fine and Windows 7 can read the 2 512 meg cards I have. Any ideas to resolve would be greatly appreciated.

are the 8 gig cards SDHC? if so your card reader may not be able to read them

When you say XP reads them fine, are you using the same card reader on XP as on Win 7? As pebbly said, your reader will need to support SDHC to read cards greater 2G. If you are using the same reader and it works on XP but not Win 7 then I would go to the mfgr. website to see if there is a driver for Win 7 or Vista. Also, are you running 32 or 64 bit?

I know you're only having probs with a 8 Gigs card...

But try to install this update from Microsoft kb976422...or maybe you have it already?

How old is your system. I have the same problem with a 3 year old laptop. But at that time SD-HC cards did not yet exist. So the readers are not designed for it. And it does not seem to be a driver problem, it is the physical reader. But all my PCs that are younger than 2 years can read those cards without problems - Vista and Windows7.
