I recently downloaded hundreds of images successfully from two different SDHC cards. Having enhanced them and deleted the ones I didn't want my next step was going to be to download them onto a couple of other SDHC cards, however when I opened Computer I found that none of my cards (of varying sizes) was recognized. Why would they have been recognized a week ago but not now? Is there a simple fix?

Why didn't I think of that? I did as you suggested and the original card from which I uploaded my images is recognized. my other two cards are not. I now suspect that the latter cards, which I bought via eBay, are faulty. It is rather suspicious that when I tried to use these cards in my camera whilst overseas they didn't work.
