A few years back I purchased an Edge 9-in-1 USB card reader from newegg that has worked perfectly in Windows XP. I have a Canon SLR that takes Compact flash and a Canon Elph that takes SD cards. Anyway, since switching to Windows 7 RC 64-bit I can not get the 2GB card to read correctly. All smaller cards read fine with the Edge reader in Win 7. But when I insert the 2GB card I receive a messaging stating "you need to format
the disk in drive G: before you can use it. Do you want to format it?" If I select yes, it brings up the "format disk" box, but shows the capacity as being 969mb.
However, if I put the same card reader and the same card back in a Windows
XP box, it reads it fine as being 2Gb.

So my main problem is that I am unable to write files to the card under Windows 7. I want to load a 2GB card with photos to use in a digital picture frame. If I leave the SD card in my ELPH I can connect it to windows 7 and I'm able to pull picutres off the card, however I can not write files to it. So now I have no way of writing to the card from within Windows 7.

The reader seems to work fine and there are no drivers that get installed with it. It's just basically a mass storage device so there is no drivers to update.

Anyone else run into this issue with 2GB SD cards in Windows 7?

I just pulled my 2GB SD card out of my camera, fired up my Win 7 system, and put the 2GB SD card in the reader/writer (Dynex.)

My Win 7 is RTM.

It came right up - all pics are there. No problems reading or writing.

Seems to me that you may have a bad reader/writer. I have a Canon DSLR and 2 smaller Canons. I use CF and SD, but, I have never liked multi-readers. I always use separate USB reader/writers.

SanDisk makes good ones- but I find that as long as they are single slottersk, they are all pretty good. I carry a SanDisk and a Siig in my camera bag.

I prefer SanDisk for an external reader / writer ... they seem to be the best in my view and are not very expensive.
