I have a 3.5 bay card reader in my computer with the typical inputs (MS, SD, CF, and so on). It has served me well over the years but I now have a big problem. I recently went out and bought an 2GB SanDisk SD2 card. The card works in my Canon PowerShot A540 as did the normal SD cardshowever, when I go to put it in my card reader, it will not read it. I'm assuming this is because SD2 is a different type of structure or format that the SD slot will simply not read. I know there are the typical portable card readers that will read SD2, but are there any internal (like my 3.5 reader) that will support the SD and SD2 card formats? If I have to I will get a portable type reader, though I don't like them but would like to know if there are any internal ones out there.
I have never heard of an SD2 card and I do not see any references to such a card anywhere else online. There are SD cards and SDHC cards. However, SanDisk's website does not show any 2GB SDHC cards at the moment. SDHC cards can be read in an SDHC card reader, but not an SD card reader. SDHC card readers will read both SDHC cards and SD cards. The difference between SD and SDHC is that SDHC is formatted in FAT32, which allows for higher storage capacities. Looking at the specs for the A540, it looks like it doesn't take SDHC cards, so I have no idea what this SD2 card is that you're speaking of.
Visit SanDisk's website and download the drivers for your SD card.
